Engineering Excellence in
Gold Processing.
Green Ngoria Supplies Ltd is a specialist consultancy company dedicated to the design, construction, and optimization of gold processing plants across East Africa.
Headquartered in Bondo–Nango with an operational spares and reagents branch in Migori, we bridge the gap between metallurgical science, structural fabrication, and on-site operation. We ensure your ore yields maximum gold output with optimal reagent consumption and zero unnecessary downtime.
Specialized Gold Processing Metallurgy
Flowsheet design, diagnostic bottle roll tests, cyanidation kinetics, and counter-current carbon adsorption optimized for your specific ore body.
Local Spares & Reagents Hub in Migori
Warehoused high-chrome slurry pump wear parts, activated carbon, and process reagents stocked locally for immediate dispatch.
Turnkey EPC & Commissioning Guarantee
From engineering drawings to concrete pouring, tank erection, piping, and first-gold smelting — executed with uncompromising quality and HSE standards.

Small Scale Mining
Artisanal & Modular Skid-Mounted Gold PlantsEngineered for artisanal cooperatives and small concession holders requiring high-efficiency modular CIP/CIL gold extraction with low initial capital and rapid on-site commissioning.
- Primary jaw crushing unit with vibrating grizzly feeder for -20mm primary discharge
- Compact overflow rubber-lined ball mill with closed-circuit spiral classifier or mini cyclone
- Centrifugal gravity gold concentrator for early coarse free-gold capture (up to 40% gravity recovery)
Medium Scale Mining
Commercial Semi-Automated CIP/CIL Leaching PlantsFull-scale commercial plant engineering, automated leaching circuits, continuous carbon regeneration, and reliable spares support to ensure maximum runtime and recovery.
- Two-stage closed-circuit crushing: Primary jaw crusher + secondary cone crusher with vibrating sizing screen
- Heavy-duty continuous overflow ball mill with hydrocyclone cluster classification loop
- Dual trash screens to prevent wood fibers and oversized debris from entering carbon adsorption train
Large Scale Mining
