cyanide process | Infoplease

cyanide process or cyanidation, method for extracting gold from its ore. The ore is first finely ground and may be concentrated by flotation; if it contains certain impurities, it may be roasted. It is then mixed with a dilute solution of sodium cyanide (or potassium or calcium cyanide) while air is bubbled through it.

How Is Gold Extracted From Gold Ore? | Sciencing

Several processes can then be used to separate the gold from the ore. The most common techniques in the United States use cyanide in various ways. In one, the ground ore is put into a tank containing a weak cyanide solution and zinc is added. The zinc causes a chemical reaction which separates the gold from the ore. The gold is then removed from the solution with a filter press.

gold cyanide processing - Bewust Outdoor

2019-11-02 Gold cyanidation, also called cyanide leaching, is a process used to extract gold from raw ore taken from the ground. It uses cyanide to dissolve the gold within the rock, which, itself, is not soluble in cyanide. The gold is then drawn out in a liquid form that can be treated to remove the cyanide.

The use of cyanide in gold mining - The …

In recent years the use of cyanide in gold mining has become the dominant means by which gold is extracted from a body of ore. The mercury amalgamation process had previously been used but recovered only about 60 per cent of an ore body's gold. In contrast, leaching finely ground ore with cyanide can recover up to 97 per cent of the ore body's gold. The process involves: Removal of all ...
