gold extraction

Gold extraction involves separating gold from the surrounding rock and ore. The process typically begins with crushing the ore into smaller pieces, then using methods like grinding, flotation, or heavy media separation to concentrate the gold. Chemical processes, such as cyanidation, dissolve the gold from the ore into a liquid, which is then treated to recover the gold particles. The recovered gold is melted and refined to produce pure metal. Overall, it combines physical and chemical techniques to efficiently and safely extract gold from mined material.
