1987-1-1 Microwave energy was applied in the pretreatment of a typical refractory arsenopyritic gold concentrate. More than 80% of As and S were volatilized off as As 2 O 3 and SO 2; whereas iron was oxidized mostly to hematite (Fe 2 O 3). All the gold was present in the calcine which responded favourably to the conventional alkaline cyanidation process and yielded 98% of Au and 60% of Ag

2007-9-1 With regards to the application of microwaves to refractory gold ores, Haque, 1987a, Haque, 1987b has studied the microwave pretreatment of refractory sulphidic ores and achieved gold extractions of over 98%. However, there is no information published on the microwave processing of the double refractory gold ores.

Double refractory gold ores, such as Barrick’s Goldstrike ore, contain both pyrite and carbonaceous matter and the latter results in the loss of gold from solution during cyanide leaching. One possible remedy is to roast the ore and thus oxidize the pyrite and remove the organic carbon. In this research, microwave roasting of a double refractory ...

Kyuesi and Haque, etc. have studied the role of microwave in the gold extraction process of arsenic-bearing refractory gold ore. 8,9) Haque K E used microwave to dispose of arsenical pyrite and gold concentrate with pyrite, the gold leaching rate reached 98%. 10) Liu Quanjun etc. made a test for a gold mine in Guizhou province. The ore without micro-wave pretreatment could be hardly leached in cyanide.
