A 100TPD rock gold CIL Carbon In Leach processing plant is a standardized turnkey hydrometallurgical facility customized for medium-sized hard rock gold mining projects, designed for a daily processing capacity of 100 tons of raw rock gold ore. As the most cost-effective modular CIL gold extraction solution for mid-scale mines, this integrated plant combines synchronous cyanide leaching and carbon adsorption in one production circuit, delivering high gold recovery, stable daily output, and simplified on-site operation compared with traditional gravity separation and segmented CIP processing lines.
Core Carbon In Leach Working Principle For Rock Gold
CIL, short for Carbon In Leach, is an optimized one-stage cyanidation gold extraction technology optimized for rock gold ore, different from two-stage CIP Carbon In Pulp processes. The 100TPD rock gold CIL processing plant integrates gold cyanide dissolution and activated carbon adsorption inside the same group of agitated leaching tanks to cut intermediate pulp transfer links and reduce fine gold loss.
After rock gold ore is crushed and ground into qualified fine pulp, lime is added to stabilize pulp pH at 10-11 to prevent cyanide decomposition. Sodium cyanide dissolves free and fine embedded gold particles inside rock gangue to form soluble gold-cyanide complexes under continuous aeration. High-quality coconut shell activated carbon is added directly into leaching tanks to instantly adsorb dissolved gold complexes. Through counter-current movement between ore pulp and activated carbon, gold is continuously enriched on carbon surfaces. Loaded carbon is screened out for desorption, electrolysis and smelting to produce high-purity gold bullion. A standardized 100TPD rock gold CIL plant maintains a steady gold recovery rate of 92% to 96% for conventional free-milling hard rock gold ore.
Full Daily Processing Flow of 100TPD Rock Gold CIL Plant
The 100TPD rock gold CIL processing plant follows a complete closed-loop daily production workflow calibrated for 100 tons daily rock ore feeding volume. Every section is matched for daily cycle operation, avoiding material backlog, incomplete leaching and carbon abrasion problems in mismatched small CIL lines.
Raw rock ore pretreatment is the front-end preparation procedure. Bulk hard rock gold ore undergoes two-stage closed-circuit crushing via jaw crusher and fine crusher, then classified by vibrating screens. Qualified rock particles enter closed-circuit grinding units composed of ball mill and hydrocyclone, ground to 200-mesh fineness to realize full monomer dissociation of embedded gold from rock gangue minerals. Thickener dewaters ground pulp to reach standard leaching pulp density for follow-up CIL reaction.
Integrated CIL leaching and adsorption is the core production section. Conditioned ore pulp flows sequentially through multi-group anti-corrosion CIL leaching tanks. Automatic aeration systems supply sufficient oxygen for gold dissolution, while intelligent dosing systems add cyanide and lime steadily. Activated carbon moves counter-currently with rock ore pulp to adsorb gold complexes synchronously. Separated loaded carbon is delivered to desorption electrolysis units for gold stripping, and gold mud is collected for high-temperature smelting into finished gold ingots.
The final eco-friendly treatment stage handles barren pulp and waste water. Residual cyanide in tailing pulp is degraded via professional detoxification devices. Process water is recycled back to crushing and grinding sections, while harmless solid tailings are filter-pressed for dry stacking, realizing zero illegal discharge and compliant daily production.

Exclusive Advantages of 100TPD Rock Gold CIL Processing Plant
Compared with small 50TPD CIL plants and large 200TPD industrial CIL plants, the 100TPD rock gold CIL processing plant has targeted advantages for medium-sized hard rock gold mining projects.
Integrated CIL process cuts operational costs effectively. Different from CIP plants requiring independent leaching and adsorption workshops, the 100TPD CIL design combines two procedures into one tank group, saving workshop construction area, pipeline layout and intermediate pulp transportation cost. It shortens the whole gold extraction cycle by nearly 40% and reduces daily labor workload for on-site workers.
Stable high recovery for rock gold minerals. Optimized tank aeration speed and carbon feeding dosage are calibrated for rock gold structural characteristics. It effectively captures fine micro-gold embedded in rock veins that gravity separation equipment cannot recover, bringing higher comprehensive gold yield than traditional rock gold gravity processing lines.
Moderate investment and fast return on investment. As a medium daily-capacity CIL plant, it avoids ultra-high capital investment of large-scale CIL factories, and delivers much higher daily gold output than miniature beneficiation lines. The modular assembled structure shortens site installation period, enabling mines to put into production within 25-35 days after site foundation completion.
Compliant green production for rock gold mines. Equipped with full sealed leaching structure and automatic cyanide degradation system, the 100TPD CIL plant eliminates cyanide leakage risk. All tailings and discharged water meet international mining environmental standards, helping medium rock gold mines pass local mining audits and obtain long-term operation permits easily.
Applicable Rock Gold Ore Types & Mining Project Scenarios
The 100TPD rock gold CIL processing plant is professionally developed exclusively for hard rock gold resources, not suitable for loose placer gold materials. It achieves optimal extraction performance for quartz vein rock gold, weathered oxidized hard rock gold, low-sulfide rock gold, and fine-grained disseminated rock gold ore. It can also process residual rock gold tailings from previous gravity separation processing.
Main application scenarios include newly-built medium hard rock gold mines, old rock gold gravity plant technological upgrading, cooperative joint mining projects, remote mountain rock gold development sites, and small mining zone standardized leaching projects. It can operate independently as a full-set gold production line, or match pre-flotation units to process moderately sulfide-bearing refractory rock gold ore without overall line reconstruction.
Daily Operation & CIL Efficiency Optimization Guidelines
To maintain stable 100 tons daily rock ore processing volume and high gold recovery rate, standardized daily operation is essential. Operators must keep uniform rock ore feeding volume to prevent pulp density fluctuation inside CIL leaching tanks, which will affect gold dissolution efficiency.
Keep stable pulp pH value between 10 and 11 via automatic lime dosing, which is the key to avoid cyanide invalid decomposition. Adjust aeration volume according to rock gold grade changes, ensuring sufficient oxygen for chemical reaction. Inspect activated carbon particle integrity daily, screen broken fine carbon timely to avoid carbon loss and gold adsorption capacity decline.
Implement weekly maintenance for aeration pipelines and tank stirring devices, and regular carbon thermal regeneration to guarantee stable adsorption performance. Clean detoxification tank sediments periodically to ensure qualified waste water treatment effect and sustainable daily CIL production.
Difference Between 100TPD CIL and CIP Rock Gold Plant
Many medium rock gold investors confuse 100TPD CIL and CIP plants, and their application differences are clear for hard rock processing. The 100TPD CIL rock gold plant adopts simultaneous leaching and adsorption, featuring shorter production cycle, smaller site occupation and lower infrastructure cost, ideal for conventional ordinary rock gold ore.
The 100TPD CIP plant separates leaching and adsorption into independent systems, with lower carbon abrasion rate and higher finished gold purity, more suitable for high-impurity complex rock gold ore. For medium rock gold mines pursuing low operation cost and fast production launch, the 100TPD CIL processing plant is the priority selection.
The 100TPD rock gold CIL Carbon In Leach processing plant is a mature modular turnkey hydrometallurgical solution tailored for modern medium-sized hard rock gold mining projects. With integrated synchronous leaching-adsorption design, PLC automated control, high rock gold recovery rate, modular easy-install structure and eco-friendly closed-loop treatment system, it solves low yield, high consumption and complicated operation pain points of traditional rock gold beneficiation lines.
