"We expose the ore, as it flows through the process, to the microwave treatment for a very short period of time, and what happens is certain mineral phases within the ore heat in response to the alternating electromagnetic field. This heating creates stress, which creates fractures within the structures of the material.

Study on Vacuum Roasting Pretreatment of Carbonaceous Gold ... - Hindawi

Carbonaceous gold ores are difficult to treat because of the "preg-robbing" by carbonaceous matters and locking by minerals.

Microwave Smelter : 8 Steps (with Pictures) - Instructables

To help focus the energy of the microwave I used silicon-carbide, which is a microwave susceptor: meaning it absorbs microwave energy and turns it into heat energy. Silicon-carbide can be found in block-knife sharpeners, but I found they were too expensive. Instead, I used a silicone-carbide rubbing stone for under $14 found at the hardware store.

Extracting Gold | HowStuffWorks

To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravel-like material then enters rotating drums filled with steel balls.

Rcovery of gold in pyritic ores - mine-engineer

Using cyanide to recover gold from sulfide ores generally results in 30 to 35% recovery, and the best I have heard of is around 50% recovery. The fine coating of a iron compound definitely appears to be a key component of the inability of cyanide to efficiently leach low grade pyritic ores. Perhaps there is some room here for a pretreatment, to ...
