Project Overview
WSHT completed a turnkey EPC (Engineering, Procurement and Construction) project for a 500 tonnes-per-day copper sulfide processing plant in the Democratic Republic of Congo. The project was delivered on schedule and within budget, achieving all performance guarantees.
Project Background
The client is a mid-tier mining company operating a copper sulfide deposit in the Katanga Copperbelt region. The project required a complete processing plant — from primary crushing to final concentrate — capable of producing 22-25% copper concentrate for smelting.
