In cyanidation, metallic gold is oxidised and dissolved in an alkaline cyanide solution. 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.
Some metals are held inside rocks as minerals. The rock or mineral that holds the metal is called an ore. An ore is heated with chemicals until it melts and the pure metal separates out as a liquid. The liquid then cools and hardens. A few metals, such as gold, silver, and copper can be found in pure form as metal
· Gold processing, preparation of the ore for use in various products.. For thousands of years the word gold has connoted something of beauty or value. These images are derived from two properties of gold, its colour and its chemical colour of gold is due to the electronic structure of the gold atom, which absorbs electromagnetic radiation with wavelengths less than 5600 angstroms
Flotation machine is mainly used for separation of gold, silver, copper, iron, lead, zinc, molybdenum, nickel, aluminum and other metal gold ore processing plant and processing technology mainly includes three processes crushing, milling and crusher, ball mill, magnetic separator, vibrating screen.
from crushed ore to gold pellet. Their method is as follows: The first step after crushing the ore is milling. This takes place in metal drums with hard metal rods or balls. No mercury is added. After milling, the groundup ore is flushed into a sluice. There are a variety of sluices used from one country to the next and even from one SSM

· 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 (, 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
