Gold CIP Production Line

[Introduction]: Gold CIP process adsorbs gold from cyaniding pulp by active carbon including 7 steps: leaching pulp preparation, cyaniding leaching, carbon adsorption, gold loaded carbon desorption, pregnant solution electrodeposit, carbon acid regeneration and leaching pulp.

[Application]: There are two kinds of ore suitable for gold CIP system: one is flotation gold concentrate, amalgamation and gravity tailings; the other is mudded oxidized ore.

Gold CIP Production Line


Impurity Removing of Gold CIP Process

Before the adsorption of cyaniding pulp, remove the wood chips to avoid adsorbing the gold and blocking the carbon screen.

Leaching and Adsorption of Gold CIP Process

Adding carbon in the leaching tank; the carbon absorbs gold becoming gold loaded carbon. After adsorption, carbon screen separates the carbon and pulp.

Desorption Electrolysis of Gold CIP Process

Under high temperature and pressure, gold loaded carbon separates gold mud and carbon in closed system.

Smelting of Gold CIP Process

After simple pickling and impurity removal, the gold ingots are obtained.

Desorption Electrolysis System with High Efficiency, Low Energy Consumption and Fast

Under the high temperature and pressure, this system has advantages of low cyanide, automatic controlling, high efficiency, fast and low energy consumption.

High Efficiency: When the grade of gold loaded carbon reaches 3000g/t, desorption rate can reach more than 96%.

Fast: Due to the high temperature and pressure, the time of desorption electrolysis is 12 hours shortened by 50-70%.

Low energy consumption: Due to the same temperature and fast working, the energy consumption is 1/2-1/4 of regular system.

No cyanide: Without adding NaCN in desorption solution, low cost and no pollution.

High grade gold mud, extract gold mud easily.

Automatic control: Installed level liquid control system, temperature control system, automatic control system.

Safety: With three security measures, system intelligent, automatic limit pressure and pressure release mechanism, safety valve.

Solution Cases

Gold CIP Production Line

Shanxi 1,200t/d Iron Mineral Processing Plant

The project adopted advanced, sound and energy-saving equipment and simple auxiliary facilities to cut construction costs and increase output. There was no environmental pollution, meaning that no waste water was discharged.

Crushing and screening: the final product size was -12mm. Advanced and cost-effective equipment was adopted; crushing and screening processes shared the plant for convenience; the crushing product was fine so that crushing and grinding costs were cut.

Grinding and classification: the first- and second-grinding fineness was -200 mesh (67%) and -325 mesh (88.47%) respectively. Bearing-drive energy-saving ball mill was adopted so that grinding costs were significantly reduced. Upgraded spiral classifier and fine screen were adopted in the first- and second-stage classification respectively to control the particle size strictly.

Magnetic separation: one-stage roughing and three-stage concentration. (Xinhai rubber pump was used to transport slurry.

Concentrates and tailings transportation: iron concentrates were dehydrated in the permanent magnetic filter and then transported by belt conveyor to the iron concentrates powder dump, and tailings flowedby gravity to the ditch outside the plant.
