16-18 TPD Containerized CIL Gold Extraction Process Plant
This project is a 16-18 ton/day containerized (carbon-in-leach)CIL gold extraction plant tailored by JXSC for a client in Guinea. The entire design is meticulously tailored to align with the client’s specific ore characteristics, operational model, and the actual construction conditions prevailing at the local mine site. The client’s production strategy involves purchasing pre-crushed ore from local artisanal miners, thereby eliminating the need for in-house primary mining and crushing operations. All equipment comprising the complete production line—including crushing, grinding, classification, leaching, filtration, electrolysis, and refining units—was fully pre-assembled and commissioned before shipment, with the entire system integrated within four standard 40-foot shipping containers.
Below is the detailed Installation Configuration of each container:
- 1st 40ft Container: Feeding + Hammer Crusher + Ball Mill & Classifier + Leaching Tank
- 2nd 40ft Container: 3pcs Leaching & Adsorption Tanks + Inclined Tube Thickener
- 3rd 40ft Container: 3pcs Leaching & Adsorption Tanks + Plate Filter Press
- 4th 40ft Container: Desorption Electrolysis Equipment+ Gold Melting+ Carbon Regeneration
16-18 TPD Containerized CIL Gold Extraction Process Details
(1) Feeding & Fine Crushing System:
An excavator feeds pre-crushed rock gold ore (particle size < 50 mm) into a hopper. An electromagnetic vibrating feeder situated beneath the hopper conveys the material uniformly to a hammer crusher. After being crushed to a particle size of less than 10 mm, the material is transported via a belt conveyor to a transfer hopper for temporary storage.
(2) Grinding & Classification System:
An electromagnetic vibrating feeder is also installed beneath the transfer hopper to ensure buffered feeding. The material is fed into a ball mill, where it is ground into a fine powder, achieving complete liberation of the gold elements from the ore matrix. The ball mill’s discharge flows into a spiral classifier for particle size screening; coarse sands that do not meet the required size specifications are returned to the ball mill for secondary grinding. This process ultimately ensures that 70–80% of the final discharge passes through a 200-mesh (0.074 mm) sieve, thereby meeting the requirements for subsequent leaching.
(3) Leaching Pre-treatment:
The classified, qualified ore slurry is directed into a slurry conditioning tank and then pumped via a slurry pump to an inclined-tube thickener. Before entering the thickener, the feed passes through a safety screen to remove any debris. The thickener’s overflow water is discharged into a settling pond for clarification and can then be recycled back into the production process; the underflow is directed into an agitation tank where appropriate reagents are added before being pumped into the leaching tanks.
(4) Leaching & Activated Carbon Adsorption:
Once the dissolution of gold elements is complete within the leaching tanks, the slurry flows into a series of six adsorption agitation tanks. These tanks feature dual impellers and are equipped with Roots blowers to facilitate agitation. Activated carbon within the tanks adsorbs the dissolved gold from the solution, forming gold-loaded carbon. Subsequently, a carbon lifting mechanism is used to separate and extract the gold-loaded carbon.
(5) Gold-Loaded Carbon Desorption & Electrowinning:
After passing through a safety screen to remove impurities, the gold-loaded carbon is fed into a desorption and electrowinning system operating at ambient temperature and pressure. The resulting gold slime is dried and finally transferred to a gold smelting furnace to be cast into finished gold ingots.
(6) Tailings Water Recycling System:
The tailings discharged from the adsorption tanks first pass through a linear vibrating screen to recover any residual activated carbon. The undersized tailings are directed into a tailings pond and then pumped into a plate-and-frame filter press for dewatering. The filtered water is recycled back into the production system for reuse, while the filter cake can be directly dry-stacked for disposal, fully complying with environmental protection regulations.
The 16-18TPD containerized CIL (carbon-in-leach) gold extraction process unit has been successfully implemented in Guinea. Housed within four 40-foot containers, the facility integrates the entire suite of equipment required for the process, ranging from feeding and fine crushing to gold smelting and tailings treatment. It offers a mature, replicable solution for the commercial development of small-scale, decentralized gold mines, low-grade gold deposits, and mines in regions with underdeveloped infrastructure.
The mineral processing techniques required for different types of gold deposits—such as oxidized rock gold, sulfidized rock gold, placer gold, and polymetallic associated gold—vary significantly; consequently, the use of generic, one-size-fits-all equipment often results in diminished recovery rates and lower returns on investment. As a specialized manufacturer with over 40 years of deep expertise in the mineral processing equipment industry, JXSC provides a comprehensive, end-to-end service chain—encompassing process design, equipment manufacturing, installation, and commissioning. We tailor our solutions based on key factors such as the client’s raw ore assay reports, production capacity requirements, mine site infrastructure conditions, environmental compliance standards, and operational models. We invite you to contact us to obtain a customized CIL gold extraction process design and equipment quotation. We are dedicated to crafting bespoke mineral processing solutions—including gravity separation, flotation, and CIP(carbon-in-pulp), leaching—that are optimized to maximize your profitability.

Highlight Of JXSC Design 16-18 TPD Containerized CIL Gold Extraction Plant
√ Rapid Deployment Efficiency: The entire equipment suite is integrated within four standard shipping containers. All installation and commissioning are completed before shipment, eliminating the need for complex civil engineering work on-site; production can commence simply by connecting external pipelines.
√ High Adaptability to Operating Environments: The primary crushing stage is specifically tailored to align with the client’s required operational model, thereby lowering equipment investment costs. Furthermore, all carbon-in-leach process parameters are fully customized based on the local ore grade and the characteristics of associated elements, resulting in actual gold recovery rates of 95%+.
√ Efficient Resource Utilization: The system features a comprehensive water recycling and tailings management infrastructure, achieving a water recycling rate of over 90% for production use—thereby substantially alleviating water supply pressures within the mining area. Additionally, the dry stacking method employed for tailings disposal ensures full compliance with local environmental regulations.
√ Exceptional Flexibility: The containerized CIL setup structure allows for the entire facility to be lifted and relocated as a single unit; once mining operations at the current site conclude, the facility can be rapidly transferred to a new mining area for continued use. Moreover, each module operates independently, simplifying maintenance and operations—making the system ideally suited for mining sites in Africa that may lack dedicated professional maintenance teams.
