gold steel wool cathode smelting

The gold is extracted from the cyanide solution using activated carbon The gold is removed from the activated carbon into a solution This solution undergoes electrowinning to deposit the gold onto steel wool which is then smelted into an impure gold bar These impure bars are sent to the Rand Refinery for final treatment to produce pure gold Lihir processing plant is designed to process 3 6 Mtpa of ore containing 7 2% sulphide sulphur at a gold grade of up to 13 g/t and a plant availability of 86% the soluble gold is plated on to stainless steel wool cathodes Barren solution at about 5 to 10 g/t of gold is pumped to leach for utilisation of the contained cyanide and

Electrowinning and Smelting - Resource Book Gold is recovered from pregnant (gold bearing) solution by the process of electrowinning An electric current is passed through the solution causing solid gold to plate out on steel wool Get a Price Production of Gold - West ia University

In metallurgy refining consists of purifying an impure metal It is to be distinguished from other processes such as smelting and calcining in that those two involve a chemical change to the raw material whereas in refining the final material is usually identical chemically to the original one only it is purer The processes used are of many types including pyrometallurgical and
