FLOWSHEET DEVELOPMENT FOR GOLD OREBODIES

REFRACTORY GOLD ORE PROCESSES 'Refractoriness' results in poor gold recovery by standard processing techniques, and can be due to either chemical or physical interference. An example of chemical interference is the presence of minerals in the orebody that consumes excessive amounts of cyanide and oxygen, the two components required for gold leaching by cyanidation. Another example .

How to Refine Gold: 2 Major Techniques of Gold Refining ...

Mostly, the gold obtained through gold electrolysis is usually very pure, almost %. In fact, this procedure is the best method for processing gold with the highest karatage (24 Karats = 100 percent gold). This is why gold electrolysis is very common in countries where pure gold pieces are given priority over the ones with low karatage.
