Analysts have been raving about how mining firms are set to document bumper increases in revenue because of rising international commodity prices. But that notion is based on the assumption that key parts in critical phases like mineral processing have been adopted to the hilt.
The goals of accelerating grades and recoveries of mineral aggregates environmentally friendly, safely and affordable would have been scrupulously carried out. Yet, in reality, missteps (poor planning and execution) within the filtration processes could be the distinction between improve and reduction in revenue. As far as filtration goes, fantastic margins could make a huge difference.
Reports indicate that even the utilization of advanced filtration technologies such as decanter centrifuges, screw presses and belt presses, amongst others, doesn’t offset poor implementation of filtration. Unfortunately, moisture levels that do not meet the brink (low or high) are frequently encountered. Most usually, that is attributable to ignored elements that impair the method of filtration. So, if mining firms are to attain environment friendly filtration, they have to seek sustainable ways of managing these methodically. And one of many sure-fire methods is the proper use of chemical dewatering brokers in filtration processes. Chemical dewatering brokers – which embrace surfactants, flocculants, polymers, sulfonates, and sulfates – are largely used to regulate moisture levels and improve throughput in filter applications. That is why mining firms must be more particular about the nature of the dewatering brokers and the best way they apply them (dose).
Why chemical dewatering brokers have become necessary
There is elevated obligation on mining corporations in the finest way they undertake their filtration processes. This is as a end result of rising value in working costs which is impacting on, growing scarcity of viable ore bearing rock, along with stringent environmental laws and laws.
Cost effective software and efficiency
Mining firms can only take advantage of their rising global commodity costs if they enhance efficiency and include costs. However, the rising oil prices, as a outcome of the Ukraine War will offset any envisaged increase in revenue.
Another noteworthy aspect is that skyrocketing vitality costs lend extra credence to the necessity for sound software of filtration processes. This is considering that filtration is an energy-intensive process. When poorly applied, the method results in consumption of extra power, which interprets in additional expenditure.
This necessitates that mining firms go away no stone unturned in their efforts to improve effectivity and contain costs from every out there avenue. One of the out there avenues, as regards filtration, would be within the sound utility of chemical dewatering agents.
Environment Social and Governance (ESG)
Environment Social and Governance (ESG) is not an option but an integral part of their operations, with factors earned from sound reporting used as a think about determining entry to capital. ESG rules and rules bind mining companies to be accountable for the impact of their activities on the setting, host communities, and adhere to good governance values. Pertaining to environmental friendliness, disposal laws stipulate sustainable measures governing the disposal or reuse of sludge. Usually, untreated or inadequately handled sludge incorporates natural chemical substances, poisonous metals, chemical irritants and pathogens, which may cause a quantity of diseases. When disposed of, the waste disrupts aquatic life and poses critical well being hazards in water our bodies.

Alternatively, using applied sciences that leave a small footprint on the environment is extremely recommended. For occasion, from a filtration perspective, utilizing a extra environmentally pleasant (less hazardous) chemical dewatering agents could be preferrable to xanthates. Xanthates embrace sodium ethyl xanthate (SEX), sodium isopropyl xanthate (SIPX), sodium isobutyl xanthate (SIBX) and potassium amyl xanthate (PAX).
Health and safety
Xanthates may be efficient in preserving moisture at a normal degree, however they may pose health and safety dangers. Studies carried out in varied nations show the risks of Xanthates exposure to human health.
Moreover, there is a excessive safety threat hooked up to high moisture content of transported mineral merchandise (commonly referred to as Transportable Moisture Level (TML)). When a ship is carrying ore with a excessive moisture content material (beyond the TML), there’s always a threat of foundering. In the previous 30 years, at least 24 accidents that occurred have been attributed to cargo liquefaction.
Mistakes in dewatering software
For effective filtration, mining companies have to identify the widespread lapses that impair filtration and result failure to fulfill moisture stage targets. More often than not, the next elements have an effect on the result – modifications in feed price (fluctuations on the milling feed price and grinding media), chemical and mineralogical composition or particle dimension distribution. The ensuing dewatering deficiencies can impede the next processing steps. A living proof is in iron ore pelletising operations, the place moisture ranges below 9% are required for pellet formation. Too much or too little water creates a slim moisture vary for optimum process circumstances. With reference to the particle measurement distribution, small particle dimension turns into increasingly difficult to dewater.
In order to deal with these challenges, a mining firm could additionally be prompted to increase capital expenditure (CAPEX) or extra useful resource allocation in the path of course of modification to have further or larger filtering capabilities.

Above and beyond, whereas this process is being carried out, there can be operational downtime, resulting in lack of productivity.
Addressing dewatering shortcomings
Addressing dewatering shortcomings can both pose a challenge or an opportunity, relying on how a mining company handles it.
There is a saying which matches, “A dangerous carpenter blames their tools”. Most typically, dewatering failure, which is mirrored in high moisture content material, is on account of poor alternatives and execution of processes. This is contemplating that there are complex variables related to dewatering.
Demonstrably, the focused level of dewatering mineral aggregates is attainable the place the feed price is constant, particle size distribution and mineralogical composition. Nevertheless, it has been constantly proven that the proper use of chemical dewatering brokers is a viable choice to keep production secure in periods of difficult eventualities in dewatering.
For dewatering aids to supply the specified output, precision is important. Chemical dewatering brokers must be utilized at appropriate factors. This is provided that completely different dewatering aids have various processes and intensities, which significantly have an result on the performance of mineral sludge dewatering.
Numerous features
There are numerous gains from correct use of chemical dewatering brokers in mineral mixture filtration. Dewatering agents ensure a predictable, cost-effective operation where there’s little to no requirement for CAPEX or extra useful resource allocation. Also, attaining moisture goal – reaching the dewatered state – is within shorter cycle occasions, rising filtering productivity.
Generally, what a mining firm gets from a chemical dewatering agent is an operational resource that allows a safer, steady and dependable process, with noticeable decreased manufacturing prices through filtration. Effective filtration is amongst the avenues obtainable at the disposal of mining corporations to make certain that they benefit from excessive commodity prices.
