Microwave in Minerals Processing and Metallurgy .

Certain minerals heat up in a microwave field, others do not. I have explored this for the last 10 years, funded by Barrick Gold H.O. Group, which was interested in distinguishing between gold bearing sulphides and pregnant robbing carbon. The emphasis was on selective machine sorting, using as little MW energy as allowed by sensitive IR sensors.

Microwave heating of gold ores for enhanced grindability .

The faster leaching rate of the microwave processed ore may be attributed to the thermal stress cracking due to differential heating of the individual minerals that make up the ore. Micro-cracking as observed in Fig. 3 increased the ease of access of leaching reagent to the mineral of interest and consequently, gold leaching was enhanced. In a .
