— This type of ore is not a concentrate, it is a raw ore. It must first be crushed to powder to extract the gold. Rock crushing equipment will cost many thousands of dollars even if you purchase small scale crushing equipment from China - At least US $5,000 and more likely closer to US$ 10,000.
Different types of gold ores shall adopt different kind of gold extraction method. 1. Gold ores from gold-bearing quartz veins. Mineral composition of this gold ore is relatively simple. Gold is the only mineral for collection. The natural gold particle size is coarse. It is easy for collection by simple ore beneficiation process. 2.

— Crushing Plant. The wet ore is delivered to the coarse ore bin directly from the mine and dumped through a grizzly to prevent any large rocks from lodging in the bin and causing subsequent problems in feeding the rock crusher. The stored coarse ore is crushed in two stages to produce a ¾-inch product.
Before you start swirling the pan, you could add one extra step in order to concentrate the gold further towards the edge where the water sweeps in over the material. Just tap the edge of the gold pan against your hand in a rhythmic pattern. The video below makes a great job of explaining this method, so we will simply leave it here.
— Metallurgical processing of metalliferous ores in general and gold ores in particular, consists essentially of three stages, often colloquially referred to as: Bashing (crushing); Mashing (grinding); and

It can be processed into gold concentrate or gold ore with higher gold content through mineral processing. The gold …
— Stage 3: hashing. The hashing stage (corresponding to metal extraction and recovery stages) is a little more complex for gold ores, as the optimal process flowsheet selection choice is heavily dependent on a good understanding of two fundamental geometallurgical parameters, the gold mineralogical associations, and the gold particle …
— A comprehensive mineralogical and physico-chemical examination of two refractory gold ores and concentrates from the Ghanaian gold province was conducted to gain a better understanding of the differences in performance of gold cyanidation. Both ore were mainly silicates, carbonates, oxide, phosphate and sulphides.
