    Challenges And Opportunities In The Recovery Of Gold

    Gold processing - gold processing - Mining and concentrating The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then.TCB International is an ore processing facility that extracts the following precious metals gold, silver, and platinum group metals.
