The Intec Copper Process: Activity in British Columbia

The Intec Copper Process is an internationally patented hydrometallurgical process for the extraction of pure copper and precious metals from sulfide concentrates. Developed and proven in Sydney, Australia at a cost of US$15m over the last ten years, the Intec Copper Process is now ready for commercial application. The Intec Copper Process has several notable advantages over both smelting and other hydrometallurgical processes. Starting from a base of substantially lower capital and operating costs than any other conventional or developing process, the Intec Copper Process is economically viable at capacity levels as low as 15,000tpa-Cu, and capable of accepting low grade and metallurgically complex concentrates. Precious metals are recovered within the Intec Copper Process circuit, without the need to re-treatment of the environmentally stable solid residues. The Intec Copper Process offers the lowest energy consumption of the available technologies, with no liquid emissions or production of noxious gases. Unlike smelting, sulfur is recovered in the solid residues in elemental form.
