When gold dissolution is complete, the goldbearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent in large tanks equipped with agitators.
#0183;#32;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
First, gold in the goldbearing ore reacts with cyanide to form a complex into the solution, and then the gold is removed from the solution to metal by a displacement reaction using reactive metal such as zinc. The reaction equation is: 4Au+8NaCN+2H2O+O2=4Na [Au (CN) 2] +4NaOH 2
#0183;#32;Crush and mill the gold ore to dust like particles. Ore is put into the crusher, which breaks it up. Water is added during the process which, when mixed to the ore particles, creates a pulp. The ore in the pulp is then ground into smaller particles and pulverized into a ball mill.

The safest way to extract gold from rocks at home is to crush the rocks. However, you might use mercury to extract the gold if youre able to obtain some, though this is dangerous.
how is gold removed from the ore Gold ore processing In placer mines, the gold is recovered by gravity separation. (18,100 square metres (195,000 sq ft)). The gold can be removed from the carbon by using a strong solution of caustic soda and cyanide, a process known as elution.
