Extraction of gold using cyanide

Extraction of gold using cyanide Gold is found in very low concentrations in the ore from which it is mined To collect the gold from the ore it needs to be separated from the other minerals in the ore To do this the gold needs to be made into a soluble form so that it can be separated from the other minerals as gold is insoluble...

How is cyanide used in gold mining?

Nov 09, 2019· Cyanidation is used to extract gold from a finely ground ore material in a mix with water at about 55% solids by mass Gold extraction is always a surface processing based extraction process and has nothing to do with the process of Mining itself....

Cyanide Use in Gold Mining

Cyanide's efficiency makes mining more wasteful Because cyanide leaching is very efficient, it allows profitable mining of much lower ore grad Mining lower grade ore requires the extraction and processing of much more ore to get the same amount of gold Partially due to cyanide, modern mines are much larger than before cyanide was used;...

Gold processing

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 (eg, 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 heaps for ....

What is Gold Cyanidation? (with picture)

May 16, 2020· 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...

Extraction of gold using cyanide

To make gold soluble sodium cyanide (NaCN) is added and the cyanide ion forms a complex ion with the gold This complex ion, [Au(CN)2]-, is readily soluble Issues of gold extraction using cyanide: Cyanide is toxic to animal and plant life and may cause death if exposed to high enough dos Free cyanide is cyanide ion (CN-) and hydrogen ....
