Water is a vital resource on which many industries rely and which should be used more sparingly. An example is the beneficiation of mineral ores. Taking the raw material fluorite as their example, researchers at Helmholtz Institute Freiberg for Resource Technology (HIF) have now shown how water usage can be optimized. They have developed a new procedure that extends the simulation of the beneficiation process. It indicates the circumstances in which it makes sense for water to be recycled without incurring losses during ore enrichment. The consumption of fresh water can thereby be significantly reduced. This not only benefits the environment but also the mining companies, because it makes the extraction of raw materials more efficient. The researchers have presented their new procedure in the Journal of Environmental Management.
