Medium Scale Mining
Commercial Semi-Automated CIP/CIL Leaching Plants
Full-scale commercial plant engineering, automated leaching circuits, continuous carbon regeneration, and reliable spares support to ensure maximum runtime and recovery.
Operational Architecture & Mineralogy Fit
Commercial mining operations require robust mechanical reliability, automated reagent regulation, and continuous slurry classification to maintain steady profitability. Green Ngoria engineers custom-sized closed-circuit milling and cascade CIP/CIL tank trains with advanced hydrocyclone classification, pressurized Zadra elution skids, and continuous rotary carbon regeneration kilns. Built to withstand abrasive quartz feeds with >95% mechanical availability.
Step-by-Step Mineral Extraction Flow
How ore advances through crushing, closed-circuit milling, agitated leaching, carbon adsorption, and final gold bullion smelting.
Two-Stage Crushing & Sizing
ROM ore is crushed through jaw and cone circuits into -12mm aggregate, monitored by weightometers.
Closed-Circuit Ball Milling & Classification
Slurry is ground in the ball mill and classified via hydrocyclone cluster to achieve optimal P80 liberation size.
Cascade Leaching & Counter-Current Adsorption
Slurry advances through 6–8 agitated tanks while activated carbon moves counter-currently, capturing gold dissolved by cyanide.
Elution, Regeneration & Smelting
Loaded carbon is stripped at 135°C, electrowon onto steel cathodes, and smelted into 90%+ pure gold bullion bars.
Core Equipment Package Included in This Tier
Every mechanical component is fabricated with high-wear metallurgy and pressure-tested before shipment.
Heavy plate shell, high-chrome or rubber liners, 75–250 kW drive
6–8 welded mild steel tanks (80–250 m³) with planetary gearboxes
Polyurethane lined 250mm cyclones with radial manifold and pressure gauges
1.5–3.0 tonne carbon column capacity with automated heat exchangers

150 TPD Commercial CIP Plant Turnkey EPC
The Operational Challenge: Client was losing fine gold in tailings due to poor agitation and manually batched cyanide dosing resulting in high chemical wastage.
Green Ngoria Solution: Engineered and constructed a turnkey 150 TPD 6-tank cascade CIP plant with automated cyanide dosing and pressurized Zadra elution.
Certified Engineering Deliverables Included
Every plant installation is backed by bankable engineering documentation, structural calculations, and certified commissioning certificates.
