Teck Cominco Limited is pleased to announce that its affiliate, Cominco Engineering Services Ltd (CESL) has been granted a Canadian patent for its hydrometallurgical nickel production process. The new, low-cost process extracts nickel metal directly from sulphide ore.

The new process involves autoclave leaching in a mixed chloride / sulphate environment that extracts the dissolved nickel by solvent extraction and electrowinning and eliminates the sulphur dioxide gas generation typical of nickel smelters. The process is an environmentally sound, low capital cost alternative to nickel smelting with broad applicability in the industry. It was developed at CESL’s Vancouver based pilot plant facilities between 1996 and 2002.
