Gold Oxidized Ore CIP Processing

 

Gold Ore Processing Methods

 

I . Gravity Separation Method

 Introduction

The gravity separation method sorts minerals according to the difference in mineral relative density (usually called specific gravity). Mineral particles with different densities are subjected to fluid dynamics and various mechanical forces in the moving medium (water, air, and heavy liquid), resulting in suitable loose stratification and separation conditions, so that mineral particles with different densities are separated.

II. Mixing Mercury Gold Separation Method

The amalgamation method can be divided into internal amalgamation and external amalgamation according to its production method. In placer gold mines, the amalgamation method is generally used to separate gold and heavy sand minerals; in vein gold mines, amalgamation is usually used as part of the combined process with flotation, re-election, cyanidation, etc., mainly used to promote the collection of coarse grains. Body gold.

III. Gold CIP/CIL Cyanide Leaching Method
 

CIL (Carbon In Leach) leaching process, that is, carbon leaching gold extraction, is a process of adding activated carbon to the pulp and leaching and adsorbing gold at the same time, which simplifies the CIP (Carbon In Pulp) process The two steps of leaching pulp and activated carbon adsorption are one step, which reduces management costs while reducing losses. Compared with the traditional CCD process, it saves 66% of the investment cost and is the preferred process for modern gold beneficiation.

 

IV. Gold Ore Heap Leaching Method

The heap leaching cyanidation method is that gold-containing low-grade ore is crushed or agglomerated into a lump of 3-10 mm, stacked on an impermeable bottom pad, and sprayed from the top of the heap with a cyanide solution to dissolve the gold in the ore The gold-bearing precious liquid percolates out of the mine heap and pools into the precious liquid pool. The gold-containing precious liquid obtained by heap leaching can be recovered by metal zinc replacement method, activated carbon adsorption method, etc., and the recovered lean liquid is returned to the heap leaching operation for recycling.
