Process introduction

Crushing and screening

Usually, one-stage or two-stage crushing process can be adopted. The raw ore materials are fed into the crusher from the feed bin and crushed to a certain particle size. The crushed products are fed into the vibrating screener. The screened materials return to the crusher, and the screened materials enter the next stage to wait for grinding. If two-stage crushing is adopted, the screened materials enter the second-stage crusher for fine crushing.

Grinding and Classification

The grinding stage generally further crushes the gold ore particles after crushing to reach the selectable particle size. This stage has one closed-circuit grinding and two closed-circuit grinding processes according to the particle size requirements. When the crushed product is fed to the ball mill by the feeder car for grinding, the milled product is fed to the classifier for classification, the overflow is returned to the grinding, and the bottom flow enters the separation stage.

Flotation

The ground product is pumped into the hydrocyclone and then into the mixing tank, and then into the analytical column through the leaching tank. A part of it is produced as tailings through the concentrator and filter.

Electrolytic smelting

The leached ore becomes gold-carrying carbon, which is removed by an analytical column. The raw material is then refined by an electrolytic cell and calcined into gold nuggets by a metallurgical furnace.
