Gravity Process in Gold Processing Plant

  1. Crushing and Grinding stage

The extracted ore should be crushed by jaw crusher initially and then by the fine crusher. When it gets the reasonable fineness, it is transported into ball mill by elevating conveyor and belt feeder.

  1. Classifying stage

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.

  1. Beneficiation stage

The super fine particles from ball mill will feed into shaking table concentrator through the hydraulic classifier, 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 of gold wash plant has more than 30 years experiences. It enjoys a very high, up to 95% high recovery rate which widely used to concentrate free gold.

  1. 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.

 Flotation Process for Rock Gold Recovery:

  1. Crushing and Grinding stage & 2.Classifying stage are the same as Gravity process.
  2. Mixing and Flotation stage

The classified ore gets into mixing tank for fully mixing. At this stage, the chemical agent for foam can be added. After fully mixing, the slurry will enter into flotation machine.

When the flotation equipment works, the motor drives the impeller to revolve, so the centrifugal effect and negative pressure are produced. On one hand, ample air is absorbed and mixed with mineral slurry, on the other hand, the mixed mineral slurry is mingled with additive, meanwhile, the foams are thinning, the mineral is bounded with foams, and floats up to the surface of mineral slurry and the mineralized foam is formed. The liquid surface can be adjusted with the height of adjustment flashboard so that the useful foams are scraped with a squeegee.

3.Concentrator thickening and drying

Then gold is separated from others. Since the separated ore is wet, they should be dewatered by thicker initially, and dried by a dryer.

JXSC is a gold processing plant manufacturer, find qualified gold ore processing plant equipment in China, applied in alluvial gold, mineral process. Get the related gold mining equipment include stone crushers, mineral separator, shaking table, spiral classifier, etc.
