ZINC CYANIDE

Cyanide process also known as cyanidation is the most widely used process for extracting gold and silver from ores The ores are powdered grounds and can be concentrated by flotation It is then mixed with dilute solutions of sodium (or potassium or calcium) cyanide while air is bubbled through it to form the soluble complex ion Au(CN) 2-1 The precious metals are precipitated from solution by zinc Get price
