Electrowinning Equipment Supplier to Africa's Mining Industry

Since 1993, CSI Mining has built long-term supply relationships with base metal refineries, copper SX-EW operations and precious metal refiners across Africa. Our electrowinning cells, insulator blocks, capping boards, electrode spacers, anode buttons and edge strips are in active service at mine sites from the South African Highveld to the DRC Copperbelt.

Zambia Copperbelt — Copper Electrowinning Equipment

Zambia is one of CSI Mining's primary export markets. We supply UNICELL® electrowinning cells, polymer concrete insulator blocks, stainless steel cathodes and consumables to copper SX-EW operations on the Copperbelt, with regular deliveries to Lusaka, Kitwe, Ndola, Chingola and remote mine sites throughout Zambia.

DRC Congo — Cobalt & Copper Electrowinning

The Democratic Republic of Congo, particularly Katanga Province, is a key market. We supply cobalt electrowinning cells, acid-resistant insulator blocks and custom-engineered tankhouse equipment to DRC operations processing both copper and cobalt.

South Africa — Base Metal & Precious Metal Refineries

As a Gauteng-based manufacturer, CSI Mining offers South African refineries the fastest lead times for electrowinning components. We supply insulator blocks, capping boards, electrode spacers, edge strips and cells to copper, zinc, nickel and gold refinery operations across Gauteng, Limpopo, the Northern Cape and North West Province.
