inquiry Gold mining is attracting increasing attention in many countries of the world. On the other hand, this sector causes numerous environmental and human health issues. The main problems are associated with: (i) Acid Mine Drainage (AMD) with low pH values and high concentrations of heavy metals, (ii) using large quantities of hazardous chemicals such as mercury and cyanide and (iii) mining dust.
inquiry The first step in gold extraction is leaching the gold which turns gold in solid form to liquid with cyanide in the presence of oxygen. Next, the gold adsorbs to the activated carbon. Finally, the carbon and gold complex is sent to elution where it is washed, and transferred to electrolysis where the gold is fully recovered.
inquiry The process causes heavier molten impurities to settle to the bottom, while the lighter molten gold floats above it. This happens for the same reason that oil floats on water - owing to its density. Finally, the molten gold is extracted and cooled in the shape of the gold bar that we all know of.
