pretreatment of refractory gold ore with microwaves
Process for treating refractory gold ores by roasting ...
The gold ore must be pretreated to oxidize sulfide minerals associated with gold and to remove other minerals and chemical compounds that interfere in the cyanidation leaching process. The recovery of gold from refractory sulfidiccarbonaceous ores after roasting pretreatment was studied. ... Process for treating refractory gold ores by ...

Crowave Pretreatment Refractory Gold
Crowave Pretreatment Refractory Gold. USA Microwave treatment of metal bearing . For example, it is known that refractory gold concentrates can be treated with microwaves to, for example, transform pyrites into pyrrhotite and hematite, the latter being more reactive than the former and thus more readily processed by conventional techniques.

Refractory Gold Ore Treatment Methods
At the plant of the Consolidated Murchison Co. in the Transvaal, South Africa, where a refractory highantimony gold ore is being treated, flotation and cyanidation of the flotation concentrates and tailings are being practiced. The association of the antimony and gold is very intimate, and during 1946, while the antimony recovery amounted to per cent, only per cent of the contained gold was extracted.

leaching circuits, even when the ore is finely ground. The cause of low gold recoveries can be either through the presence of naturally occurring 'preg robbing' carbonaceous materials or gold physically 'locked' in sulphide minerals. The majority of gold ores are classified refractory because the gold mineralogy is contained in sulphides.
