Mining activities – extracting, processing and refining – generate air emissions and waste including tailings (the rock slurry that remains after removing the desired minerals). Reducing mine waste and improving chemical management through recovery and recycling throughout the mine lifecycle lowers risks and costs and supports our commitment to operate in a responsible, sustainable manner.

Gold ore is processed by all-sliming cyanidation CIP (carbon in pulp) at a gold mine in Gansu province of China. The leaching residue (tailing) Au grade is about 0.52 g/t, which is much valuable to be recovered. Mineralogical analysis shows that the loss of gold in leaching residue is mainly organic carbon adsorption gold and inclusion gold, accounting for 45.55% and 54.45% respectively.

When rain falls on tailings, it leaches away materials that can create water pollution, for example, lead, arsenic, and mercury. Sulfuric acid is sometimes produced when water interacts with tailings, or it can be a by-product of ore processing. As a result, highly acidic water leaks from the tailings and disrupts

Mining involves the processing of mined ore to separate valuable minerals, leaving behind huge volumes of waste tailings. Driven by mining volumes, globally generated tailings are estimated to total ~3.2 bn tons for copper and ~1.8 bn tons for iron per annum.
