Yet developments in these unheralded elements of the mining process present significant opportunities to help solve some of the most pressing issues facing miners today.

One example from the industrial minerals sector is lithium. \u201cAlthough lithium processing from spodumene has been practiced successfully for some time (Figure 1), in order to meet increasing lithium demand, miners must find a competitive way to process other lithium-bearing ores, such as lepidolite and petalite,\u201d explained Parker.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As a result of this growing need to process more complex ores, \u201creagents need to be strong, yet selective against penalty elements and gangue materials,\u201d said Guitard. \u201cLower grades and higher throughputs also necessitate reagents that enable faster value mineral flotation kinetics.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cGenerally, lower ore grades necessitate the processing of more tons to yield the same amount of concentrate,\u201d agreed Parker. \u201cIn existing operations, this means that the flotation process must handle more tons within the same amount of time, leading to equipment running beyond design capacity. The flotation process therefore requires reagents that can float faster to deliver the ore to the froth zone quickly, so that it can be swiftly removed. To meet these needs, custom-formulated reagents that improve flotation kinetics, while delivering optimum grade and recovery, are a must.\u201d<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"569\" height=\"1004\" src=\"http:\/\/northamericanmining.com\/wp-content\/uploads\/2021\/08\/Figure_1.jpg\" alt=\"\" class=\"wp-image-910\" srcset=\"https:\/\/northamericanmining.com\/wp-content\/uploads\/2021\/08\/Figure_1.jpg 569w, https:\/\/northamericanmining.com\/wp-content\/uploads\/2021\/08\/Figure_1-170x300.jpg 170w\" sizes=\"auto, (max-width: 569px) 100vw, 569px\" \/><figcaption>Figure 1.

These ores \u201ccreate the greatest challenge for today\u2019s metallurgists,\u201d said Parker.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cIn some cases, mica, feldspar and high-purity quartz can be successfully beneficiated from the same deposit with better reagents, equipment and design. High purity tungsten and fluorspar can be produced using custom-designed collectors that achieve higher grade and recovery compared to commodity fatty-acid collectors,\u201d the Arkema-ArrMaz expert continued.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cUnderstanding the mining process from exploration to production optimization is key to developing reagents that can successfully discover an ore\u2019s true potential, unlocking maximum value throughout the entire beneficiation process.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A similar trend is seen in metal mines, as Solvay\u2019s Guitard noted, with tailored reagents designed to maximize the extraction of precious metals such as gold, silver and platinum, that can be sold as byproducts. These reagents enable miners to maximize their net smelter returns by capturing maximum value through both precious and base metal recovery.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"692\" height=\"739\" src=\"http:\/\/northamericanmining.com\/wp-content\/uploads\/2021\/08\/Figure_3.png\" alt=\"\" class=\"wp-image-912\" srcset=\"https:\/\/northamericanmining.com\/wp-content\/uploads\/2021\/08\/Figure_3.png 692w, https:\/\/northamericanmining.com\/wp-content\/uploads\/2021\/08\/Figure_3-281x300.png 281w\" sizes=\"auto, (max-width: 692px) 100vw, 692px\" \/><figcaption>Figure 3.

The development of safer reagents that reduce the impact of mining on people and the environment is, therefore, a top priority. For example, there is a movement to replace hazardous chemicals, such as the use of sodium hydrosulfide (NaSH) in copper-molybdenum (Cu-Mo) separation.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cThere are several issues with NaSH, including stench, risk of exposure to highly toxic hydrogen sulfide gas, performance deficiencies when treating difficult ores, and logistical challenges in handling large volumes,\u201d explained Solvay\u2019s Guitard. To solve these challenges, Solvay has introduced a depressant technology that can replace up to 60% of the NaSH and is now in commercial use globally. Its latest innovation, now in commercial use at a large copper operation in North America, achieves 100% NaSH replacement at an overall consumption of 1.5 kg\/t of molybdenum plant feed, compared with the previous 11.5 kg\/t NaSH consumption.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It is often not as easy as simply developing a replacement, however, as Paul D. Slater, vice president of mining &#8211; U.S. at SNF, explained: \u201cAlternative chemistry often creates residual effects, creating undesired byproducts, that must also be accounted for, but can be mitigated by working with end-user mining customers to provide a whole system approach solution.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Water sustainability is another key to sustainable minerals processing.<sup>1<\/sup> Two particular focus areas, according to Parker, are preserving water clarity and protecting water from aquatic toxins.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cSuspended fines often tie off collectors and other surface-active ingredients used in flotation; water free of clay and turbidity, therefore, helps to reduce reagent consumption,\u201d the Arkema-ArrMaz expert noted. Improving water clarity with flocculants is a balancing act, however, as the cost must be weighed against gains in mineral grade and recovery.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cAn application system that dynamically handles changes in flotation demands connected to water turbidity can maximize water quality at the lowest cost possible,\u201d said the Arkema-ArrMaz expert. \u201cWise stewardship and custom flocculant application systems, designed for each mine\u2019s complex water system, can keep water clean for discharge. Systems that isolate bodies of water in ponds to monitor and treat for clarity and water chemistry add another level of protection.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When it comes to protecting water from toxins, as the impact of mining chemicals on water quality and aquatic life is better understood, reagent suppliers are increasingly able to use libraries and chemical test data to develop products that are safer and more sustainable. As part of the development of new, large mines, Parker also advises specific aquatic testing on local fauna and flora at a regional laboratory.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">After safety and water use, a third key pillar of sustainability is lowering the carbon intensity of mining. As an example of the role mining chemicals can play here, sodalite scale inhibitors for the Bayer Process in the alumina industry combine sustainability and profitability, explained Ryan Zheng, global marketing manager &#8211; alumina and industrial minerals at Solvay.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cScale accumulation often leads to costly downtime, exposes workers to the acid-based chemicals needed to treat the scale, and reduces refineries\u2019 energy efficiency,\u201d said Zheng. \u201cSodalite scale inhibitors therefore contribute to significant cost savings, by maintaining high efficiency in heat exchangers, and deliver energy savings, which limit the amount of CO<sub>2<\/sub> emissions released into the atmosphere.<sup>2<\/sup> Improving heat transfer efficiency and limiting the formation of sodalite scale can also save billions of gallons of freshwater annually in alumina refineries across the globe.\u201d<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"919\" height=\"1024\" src=\"http:\/\/northamericanmining.com\/wp-content\/uploads\/2021\/08\/Figure_2-919x1024.jpg\" alt=\"\" class=\"wp-image-911\" srcset=\"https:\/\/northamericanmining.com\/wp-content\/uploads\/2021\/08\/Figure_2-919x1024.jpg 919w, https:\/\/northamericanmining.com\/wp-content\/uploads\/2021\/08\/Figure_2-269x300.jpg 269w, https:\/\/northamericanmining.com\/wp-content\/uploads\/2021\/08\/Figure_2-768x855.jpg 768w, https:\/\/northamericanmining.com\/wp-content\/uploads\/2021\/08\/Figure_2.jpg 1027w\" sizes=\"auto, (max-width: 919px) 100vw, 919px\" \/><figcaption>Figure 2. Flotation reagent testing in Arkema-ArrMaz\u2019s mining laboratory.

Indeed, a future of smart mineral processing plants is already here, utilizing fewer operators and relying on remote or virtual optimization. It\u2019s a future where plants use artificial intelligence (AI) to help predict chemical usage rates within specific applications to maximize recovery rates and lower overall operational costs, as well as to determine the ideal type of chemical for a particular type of ore being processed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, even in this digital world \u2013 where human interface is being replaced by more advanced machine control \u2013 the chemical programs, monitoring of the technology and adjustment of the parameters remain ever-important, according to SNF\u2019s Slater, in order to complement and best harness the wave of innovation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Nicolas Renaud, digital products director &#8211; mining solutions at Solvay, agreed. \u201cWe see digitalization of mining chemistry as the next phase in mining\u2019s continuous improvement journey,\u201d he explained.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cThe choice of chemistry and process conditions are inextricably linked to feed mineralogy. With increasing size, most mines trade the ability to blend ores, requiring concentrators to be adept at managing rapidly changing feed mineralogy. Chemistry is the only lever that can be changed in real time. This can be done by characterizing the feed in real time and leveraging data science algorithms to recommend chemistry and process conditions. Models suggest several percentage points of metals recovery are to be gained in this manner, along with improved water and energy efficiency.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Incorporating digital technologies into the reagent formulation process also represents a shift in chemical innovation, according to Renaud. The latest technologies can now be harnessed to deliver live formulation of reagent packages: for example, Solvay offers a 5G-enabled dosing system that enables precise blending and dosing control of building-block chemicals during mineral processing trials.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cThere are, however, still many hurdles to successfully digitizing mineral processing,\u201d concluded Arkema-ArrMaz\u2019s Parker. \u201cFor example, the sensors and analytical devices used must be robust enough to handle the abrasive and harsh conditions found in most mineral processing plants. In addition, getting a representative sample in and out of an analytical device in a dynamically-flowing system presents a significant challenge. Instrument maintenance and calibration in most industrial mineral processing plants is often troublesome, leading to ineffective utilization of the system. Developing equipment and designs to overcome the tough conditions in the plant will further enable the use of digital and AI technologies to control and monitor mineral processing.\u201d&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">One solution to these challenges is to use historical data, pulled from various sources, to create a model of process conditions that can then be used by metallurgists to see how the process responded to changes \u2013 without having to rely on laboratory experiments or plant trials. This approach has been taken by Orica, which offers a software package that can simulate changes to the gold leaching process and present the impact on tails grade (Figure 4). According to the company, by enabling data inputs beyond that of plant data, the overall model fit is significantly improved.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"698\" height=\"563\" src=\"http:\/\/northamericanmining.com\/wp-content\/uploads\/2021\/08\/Figure_4.png\" alt=\"\" class=\"wp-image-913\" srcset=\"https:\/\/northamericanmining.com\/wp-content\/uploads\/2021\/08\/Figure_4.png 698w, https:\/\/northamericanmining.com\/wp-content\/uploads\/2021\/08\/Figure_4-300x242.png 300w\" sizes=\"auto, (max-width: 698px) 100vw, 698px\" \/><figcaption>Figure 4.

As Todd Parker of Arkema-ArrMaz concludes, there is a burden on engineering firms, equipment manufacturers and reagent formulators to work together to provide viable solutions. Particularly when developing new, low-grade and complex deposits, miners are \u201cwise to work with reagent formulators, engineering firms and equipment manufacturers to understand the full potential of the ore, and develop a plant design that delivers the highest grade and recovery while keeping costs competitive.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As one practical example of cross fertilization of innovation, equipment manufacturers are now overcoming the limitations of traditional technology to develop new flotation cells that can recover material previously lost at the very coarse (+300 microns) and fine (-30 microns) ranges during sulfide minerals flotation. In response, Solvay has brought to market a line of reagents to be used with equipment designed to float coarse particles.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cPilot tests show that these reagents can boost recovery of the coarsest size particles, contributing in a major way to the efficacy of the equipment. New reagents have also been designed to allow flotation of coarser particles in traditional flotation cells (Figure 5),\u201d said Tarun Bhambhani, Principal Scientist, Mineral Processing, Solvay. \u201cIn addition, we are studying equipment designed for mitigating losses in the fine size ranges and a product line for these is under development.\u201d&nbsp;<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"677\" height=\"675\" src=\"http:\/\/northamericanmining.com\/wp-content\/uploads\/2021\/08\/NAM_Sep21_Mining_Chemicals_Figure_5.jpg\" alt=\"\" class=\"wp-image-938\" srcset=\"https:\/\/northamericanmining.com\/wp-content\/uploads\/2021\/08\/NAM_Sep21_Mining_Chemicals_Figure_5.jpg 677w, https:\/\/northamericanmining.com\/wp-content\/uploads\/2021\/08\/NAM_Sep21_Mining_Chemicals_Figure_5-300x300.jpg 300w, https:\/\/northamericanmining.com\/wp-content\/uploads\/2021\/08\/NAM_Sep21_Mining_Chemicals_Figure_5-150x150.jpg 150w, https:\/\/northamericanmining.com\/wp-content\/uploads\/2021\/08\/NAM_Sep21_Mining_Chemicals_Figure_5-400x400.jpg 400w\" sizes=\"auto, (max-width: 677px) 100vw, 677px\" \/><figcaption>Figure 5.

Slater also concludes with an allusion to collaboration between engineering and chemistry \u2013 this time in terms of developing dry and water-limited processing techniques: \u201cthe continued drive to recover all available free water and recycle within processing conditions, without drawing from outside environmental watersheds, requires a mechanical and chemical balance to these circuits in future.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It seems that in mining \u2013 as in life \u2013 finding balance is everything.&nbsp;&nbsp;<\/p>\n\n\n\n<hr class=\"wp-block-separator\"\/>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>References<\/strong><br>1.
