JXSC mine machinery factory is a professional mining machinery factory for over 30 years.
We have rich experience in GOLD, TIN, TUNGSTEN, DIAMOND, COLTAN, MANGANESE, TANTALITE, ILMENITE, CHROMITE, TANTALUM-NIOBIUM Processing Plants.
For hard quartz rock gold mining process, it usually contain below 3 separation methods:
Gravity Process for Rock Gold Mining:
1.Crushing and Grinding stage
The extracted ore should be crushed by jaw crusher initially and then by fine crusher. When it gets the reasonable fineness, it is transported into ball mill by elevating conveyer and feeder, and is milled by ball mill.
The subtle milled ore gets the next procedure: classification. There is a theory that if the weights of solid particles are different, the sedimentations will be different, and the mixed ore can be classified by spiral classifier/screw classifier.
The super fine particles from ball mill will feed into shaking table through the hydraulic classifiers, which can ensure different size distribution ore/slurry feed into different riffles shaking table, in order to reach a higher recovery ratio.
JXSC Shaking Table is one of our flagship mining equipment with more than 30 years experiences. It enjoys very high, up to 95% high recovery rate which widely used to concentrate free gold.
4.Gold refining stage
Mercury Distiller / Gold Amalgamator is the traditional gold refining machine, widely used to mix the mercury and gold concentrate, in order to get the pure gold, then we can use Gold melting furnace to produce gold bar.
