process of polishing of limegold ore

Gold processing - Gold processing -Mining and concentrating: The nature of theoredeposit determines the mining and mineral processing techniques applied. Oxideoredeposits 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 piled into heaps for ...

    Lime in Gold Ore Mining Process Flotation, Cyanidation

    The addition of lime in the flotation operation is usually carried out by adding the lime powder to the ore belt of the ball mill or adding lime milk or lime powder to the stirring tank before the flotation. The role of lime in theflotation processis most apparently the effect on the properties of the flotation foam.

    The Wohlwill processincreases purity to about 99.99percent by electrolysis. In this process, a casting of impure gold is lowered into an electrolyte solution of hydrochloric acid and gold chloride. Under the influence of an electric current, the gold migrates to a negatively charged electrode (cathode), where it is restored to a highly pure metallic state, leaving the impurities as a separate solution or residue.

    Hold the blade with right angle to the stone, and push the arms forward. For the flat surface (shinogi-ji), a little slant angle is not so bad. For the back surface, hold the blade 45 degrees to the stone, and push forward. The work is same to the next step BINSUI. This step is the most important for the shaping.
