Research highlights Microwave heating of a material leads to micro-crack formation. Micro-crack formation allows size reduction and liberation at a lower stress level. Micro-cracks generated enhances access of lixiviants to the mineral of interest. Microwave processing enhanced grindability and cyanide amenability of the gold ore.
The Microwave Kiln is simpler, less expensive and far less tedious – not to mention, more fun – than other processes, such as spiral panners or fine gold tables. All you need is a 1200 watt microwave, a few tools and you are on your way to smelting your own gold at home!

effects of the microwave roasting of a double refractory gold ore and showed that the total decrease in carbon content was grea ter, the heating rate was higher, and energy consumption was lower than with the use of conventional roasting.
Microwave Heating Applications in Mineral Processing 81 which was shock cooled through water quenching, showed no difference in the product size distribution of the material after milling. Comparisons of results obtained from the same heat treatments after comminution by slow crushing, however, indicate that quenching the
The microwave roasting of a double refractory gold ore was investigated. The TGA results showed that the three major reactions involved in the roasting process were; oxidation of pyrite, oxidation of the carbonaceous matter and the decomposition of carbonates.
In the research discussed below, a free-milling gold ore was subjected to microwave irradiation prior to grinding. The microwave heating behaviour of the ore w as investigated and the effect of this pretreatment on the grindability of the ore and the gold liberation were studied. Subsequently, the gold recovery from the
Mining - Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered.

The Effect of Ore Composition. Advantages of the Microwave Processing Technique. Summary. Background: Vast amounts of energy are used every year (3-5% of the world's total electrical energy use) in the mining and minerals processing industries to grind mined rocks and ores in preparation for subsequent processing and metal extraction.
Flux: Understanding how the GPK Flux works can help everyone with their smelting experience. The flux's purpose is to conduct the microwave energy, suspend the impurities contained in the smelted concentrates and allow the precious metals to separate from them.
After two month we treated rocks sulphides (from refractory gold ore). During the treatment from quartz-box (inside the box was sulphides) output the sulphur liquid. After we had two product- liquid sulphur & calcine. To calcine we provide leaching test. The gold recovery was 90%.
