The electrowinning circuit at Tiger Resources’ Kipoi project

Engineering and heap leach specialist SENET is unarguably Africa’s copper processing leader, having developed its expertise in this field extensively over the last decade.

Today, the company boasts one of the largest copper solvent extraction/electro-winning (SX/EW) footprints on the continent with a combined annual process production in excess of 290 000 t, writes Laura Cornish.

Unparalleled copper expertise

SENET’s copper SX/EW processing expertise ensures that it is continuously active in Africa’s central region – predominantly the Democratic Republic of Congo (DRC) – which boasts some of the world’s largest copper resources. Despite an economic downturn, which has forced numerous projects to be delayed, SENET’s copper project portfolio has continued to grow, thanks in part to innovative designs that result in aff ordable process plants.

Having completed its tenth copper SX/EW plant, which was for Tiger Resources’ Kipoi project in the DRC last year, SENET is underway with the execution of its 11th and 12th (expansion) process plants, for Shalina Resources’ Etoile copper project and Kamoto Copper Company’s whole ore leach project – both in the DRC as well.

Through its copper project execution, SENET has gained valuable knowledge which it applies towards guaranteeing the success of new projects and completing future studies with increased efficiencies and reduced schedules. “The results of lessons learnt have seen every new plant we bring on stream deliver improved copper recoveries, greater extraction efficiencies and volumes produced,” SENET project manager Geoff rey Sewell reveals. “Kipoi demonstrates this perfectly.”
