20tpd-300tpd EPC gold mining project for CIP CIL plants

1.Product Introduction CIP CIL Gold Extraction

In modern gold mining, Carbon-in-Pulp (CIP) and Carbon-in-Leach (CIL) are the dominant cyanidation techniques used to recover gold from finely ground ore. Both methods rely on activated carbon to "adsorb" (stick) gold onto its surface from a cyanide solution. While they share the same chemistry, the sequence of events differs significantly to accommodate different ore mineralogy and project economics.

2.Application CIP CIL Gold Extraction

• Target Ores: Suitable for gold extraction from oxidized gold ores, low-grade gold ores, and sulfide-bearing ores.

• Scenarios: Widely utilized in large-scale gold processing plants, eco-friendly metallurgical projects, and tailings resource recovery operations.

3.Working Principle CIP CIL Gold Extraction

CIP (Carbon-in-Pulp)

The cyanide leaching process is completed first, followed by the adsorption of gold-cyanide complexes onto activated carbon within the pulp. This achieves solid-liquid separation and metal recovery.

CIL (Carbon-in-Leach)

Leaching and adsorption occur simultaneously. Activated carbon is added directly into the leaching tanks, dissolving and adsorbing gold at the same time, which significantly streamlines the process flow.

4.Advantages CIP CIL Gold Extraction

• High Efficiency: Gold recovery rates can exceed 90%, making it exceptionally effective for treating low-grade ores.

• Economic Viability: Reduces capital expenditure (CAPEX) on equipment and minimizes chemical consumption, leading to lower production costs.

• Environmental Sustainability: The closed-circuit system reduces cyanide pollution, aligning with modern global environmental standards.

• Versatility: Capable of processing various ore types, including associated minerals containing silver and copper.
