Gold of even greater purity (99.99%) is created by more complex and expensive electrochemical Wohlwill Process. In this, an electric current is passed through an electrolyte solution of hydrochloric acid and gold chloride. Gold of 99.5% purity is used as the anode and 99.99% pure gold plates out onto the cathode. Refined gold is subject to 10-percent import duty in India as opposed to eight percent on gold …
Gold extracted by amalgamation or cyanidation contains a variety of impurities, including zinc, copper, silver, and iron. Two methods are commonly employed for purification: the Miller process and the Wohlwill process. The Miller process is based on the fact that virtually all the impurities present in gold combine with gaseous chlorine more readily than gold does at temperatures equal to or greater than the melting point of gold.
The Refiner Separates the Gold and Lead Once everything has cooled down, the refiner removes the lead button and places it in a porous cup known as a cupel. The refiner will then heat this in a cupellation furnace. When the cupel is heated, the lead seeps out through the porous holes in the cupel, leaving behind just the gold in a bead-like shape.
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 piled into heaps for ...
