1. Product Description
The 800 TPD large gold CIL plant is a standardized large-scale fixed carbon-in-leach production line designed for medium and large commercial gold mines. It is tailored for continuous all-day stable operation, and it is widely applicable to hard rock oxidized gold ore, low-sulfur sulfide gold ore, mixed associated gold ore and old tailings recycling projects.The complete set of equipment consists of heavy-duty crushing unit, two-stage closed-circuit grinding system, high-volume thickener, multi-stage series sealed leaching tank array, large-flow carbon screening system, industrial-grade high-power desorption-electrolysis integrated unit, centralized carbon regeneration furnace, automatic continuous reagent adding system, full wastewater closed circulation system, large-scale tailings detoxification station and central intelligent PLC control room.This mature fixed specification is widely delivered to Ecuador, South America, Africa and Central Asia. With stable daily throughput of 800 tons of raw ore, the whole line is configured with industrial heavy equipment to meet long-term uninterrupted 24-hour industrial mining production requirements.
2. Working Principle
It follows the classic mature CIL synchronous leaching & adsorption technological route, and adopts large-scale serialized equipment to amplify continuous production efficiency:
Crushing & closed-circuit grinding: Raw ore is crushed coarsely and finely, then delivered to closed-circuit ball mill group for fine grinding, to reach the monomer dissociation particle size of gold minerals.
Concentration & pulp conditioning: Ground pulp enters thickener for dehydration concentration, adjust pulp density, pH value and dissolved oxygen to build stable leaching environment.
Serial CIL leaching & adsorption: Concentrated pulp flows sequentially through multi-stage connected leaching tanks; cyanide dissolves gold into gold cyanide complex ions, and activated carbon continuously adsorbs gold ions synchronously with ore pulp flowing.
Loaded carbon separation: High-strength large-scale screening equipment intercepts saturated loaded carbon, and sends it to the desorption-electrolysis workshop.
Desorption, electrolysis & smelting: High-temperature high-pressure desorption strips gold from activated carbon, electrolysis precipitates high-purity gold mud, and gold mud is smelted into finished gold ingots.
Carbon regeneration & harmless discharge: Desorbed barren carbon is centralized heated and activated for cyclic reuse; tailings and wastewater are processed by detoxification and purification, then recycled or discharged up to environmental standards.
3. Core Features
Stable 800TPD continuous output: Professional industrial heavy equipment configuration, 24-hour non-stop production, small daily output fluctuation.
High comprehensive gold recovery: For conventional hard rock gold ore, overall recovery rate stably reaches 92%~97%.
Low unit consumption: Large-scale equipment reduces power consumption, cyanide consumption and carbon loss per ton of ore, cutting long-term operating costs.
Centralized automatic control: Central PLC intelligent control room realizes automatic dosing, stirring speed adjustment and real-time data monitoring, reducing manual labor.
Strong anti-fluctuation capacity: Multi-stage buffer design, stable operation under the condition of ore grade fluctuation, low equipment failure rate.
Complete environmental supporting facilities: Matched with large sewage circulation and tailings detoxification system, easy to pass environmental inspection in Ecuador and Latin America.
Mature modular split design: Convenient container split packaging and ocean transportation, simple on-site assembly and systematic commissioning guidance.
Long service life: Thickened wear-resistant materials for key equipment, durable structure, suitable for long-term large-scale mining operation.
