Microwave assisted pretreatment of refractory gold concentrate. Gold is considered to be refractory when it cannot be easily recovered by alkaline cyanide leaching. The vast majority of refractory gold occurs in sulphidic minerals such as pyrite (FeS 2), arsenopyrite (FeAsS) and pyrrhotite (FeS).
Actual industrial low recovery we have after you said tests. I think this tests don''t give full knowledge about refractory ore. The first problem is gold particles behaviour in pretreatment processes (roasting, POX, BIOX.) In roasting ore gold particles will be flay or dissolve in solid minerals (pyrite, arsenopyrite).
