Gold cip plant manufacturers

A professional Gold CIP plant consists of several critical stages: Crushing and Grinding to liberate gold, Leaching Tanks where cyanide dissolves the gold, Adsorption Tanks containing activated carbon, and the Elution and Electrowinning (Desorption) system. High-quality plants must feature high-efficiency agitators to ensure uniform slurry suspension and inter-stage screens to prevent carbon migration between tanks.

Buyers should demand a Gold Recovery Rate of at least 90-98%, depending on ore mineralogy. Ensure the supplier provides customized agitation speeds and optimized carbon density calculations. It is essential to verify the leaching residence time (typically 24-48 hours) to ensure the plant can handle your specific daily tonnage (TPD) without gold loss in the tailings.

Due to the use of sodium cyanide, the plant must comply with the International Cyanide Management Code (ICMC). Suppliers should provide Cyanide Detoxification Systems (such as INCO or Caro's acid methods) to treat tailings before discharge. Ensure all tanks meet ASTM or ISO structural standards for anti-corrosion and leak prevention to avoid environmental contamination.

The leaching and adsorption tanks should be constructed from Q235B or Q345B carbon steel with a high-grade anti-corrosion epoxy coating or rubber lining. For the elution system, which operates at high temperatures (approx. 150°C) and pressures, 316L stainless steel is preferred for the heat exchangers and columns to prevent chemical erosion and thermal fatigue.

Utilize Third-Party Inspection services (like SGS or BV) to conduct a Pre-Shipment Inspection (PSI). This ensures the mechanical dimensions and material grades match the contract. For secure transactions, use Made-in-China.com's secured payment services or a Letter of Credit (L/C) to ensure funds are only released upon verification of shipping documents.

Focus on the Performance Guarantee Clause, which holds the supplier accountable for the promised recovery rate. Negotiate for the inclusion of one year's worth of wear-resistant spare parts (e.g., pump impellers, screen meshes) and request on-site installation supervision and operator training as part of the package to ensure smooth commissioning.

Gold CIP plants are often shipped as Oversized Cargo (OOG) or in multiple 40HC containers. Ensure the supplier uses professional sea-worthy packaging with vacuum-sealed plastic for electrical components and heavy-duty steel bracing for tanks. Confirm the Incoterms (typically CIF or DAP) to clearly define who handles the complex inland transit to remote mining sites.
