State-of-the-Art Processing Facilities
Somika Commodities Limited operates modern mineral processing facilities strategically located near our mine sites in Zambia. Our main processing complex spans multiple production lines capable of handling copper cathode, cobalt hydroxide, gold and silver refining, and speciality mineral concentration.
The facilities feature fully integrated SX-EW (solvent extraction and electrowinning) circuits for copper cathode production and dedicated processing lines for cobalt hydroxide using atmospheric leaching and precipitation. Our gold and silver refinery uses advanced fire assay and electrolytic refining processes.
A fully equipped 24-hour laboratory — staffed by qualified metallurgists and analytical chemists — performs continuous quality checks on every production batch, ensuring our minerals consistently meet the specifications required by London Metal Exchange registration and international buyers.
Copper Cathode Plant (SX-EW)
Capacity: 60,000 MT/yearHydrometallurgical plant using solvent extraction and electrowinning (SX-EW) to produce 99.99% pure LME Grade A copper cathode from oxide ores and concentrates.
Cobalt Processing Unit
Capacity: 3,000 MT/yearAtmospheric leaching and cobalt precipitation circuit producing 30–35% cobalt hydroxide (Co(OH)₂). Integrated with copper circuit to maximise recovery of both metals.
Gold & Silver Refinery
Capacity: On demandFire assay and electrolytic refining producing 99.9% pure gold and silver bullion. Equipped with independent assay office for buyer verification and full certificate of analysis.
Speciality Mineral Concentration
Capacity: Varies by productGravity concentration and flotation circuits for coltan, tantalite and manganese ore processing. Produces clean, export-grade concentrates with full chemical analysis.
