9) Haque K E used microwave to dis-pose of arsenical pyrite and gold concentrate with pyrite and is selected primarily to take advantage of its low capital cost relative to other methods. Thirty-seven different heap leach operations with a total production of 198 tonnes of gold per year (6 there is often a tendency to overlook or minimize the importance of the small mine.The small mine of today may develop into the large mine of tomorrow. Under proper management and financing it has as good a chance of yielding a profit as the larger property.I have a limited amount of very high grade gold/platinum ore. I am planing to do a ssn leach then smelt the concentrates in a microwave. Iv been told the gold platinum content is almost 50 % should I pre wash to start or go straight to the smelt. thanks Bryan in denver coloradoA high carbon low-grade gold ore

000 …Refractory Gold Any ore that is not readily amenable to recovery by conventional cyanide leaching at a reasonable grind size can be considered refractory. The three primary factors that cause gold ores to be refractory are: Physical encapsulation – Extremely fine ( 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 cya-nide. On the other hand the cyanide leaching of gold oreA method of treating ore particles to facilitate subsequent processing of the ore particles to recover valuable components from the ore is disclosed. The method includes exposing the ore particles to microwave energy and causing structural alteration of the ore particles. In one embodiment structural alteration is achieve without significantly altering the mineralogy

Most of refractory gold occurs within sulphide minerals such as FeS 2 and FeAsS and are treated by roasting is a typical refractory gold ore whose conventional cyanide leaching extraction is only 12.9 %.(PDF) Microwave-assisted leaching—a review . The ore was sized wave energy may have found successful application in between 0.2 and 16 mm and was irradiated for a gold extraction is that gold-bearing minerals tend to period between 0 and 70 min in either a monomode or be good microwave absorbers
