Increase Your Metal Yield & Overall Revenue With Kell Process From Lifezone Ltd.

Neuchâtel, Switzerland, 14 May 2012 : The Kell Process, offered by Lifezone Ltd., has brought a remarkable breakthrough in platinum group metals (PGM), precious metals and base metal concentrate processing technology. With enhanced metal yield, reduced power costs, ease of processing and environmental benefits, this highly efficient and simplified process offers producers an alternative to smelting of their flotation concentrates.

Briefing about the development of the process, the inventor of the Kell Process and director of Lifezone, Keith Liddell, said, “The Kell Process was conceived as a treatment route for concentrate from the South African UG2 platinum reef. The chromite contained in UG2 concentrates creates problems in smelting and limits are placed on the amount of chromite that flotation concentrates can contain which reduces flotation recovery of the platinum and other metals. The Kell Process solves this problem completely.”

Designed to remove the constraints in smelting, Kell Process has been fine-tuned scientifically to be robust and flexible. Now the operating conditions of the process can be modified according to the needs of the concentrate that required to be processed making the process applicable to other types of concentrate containing the base metals, nickel, copper and cobalt and also gold and silver.

Liddell further added, “The Kell Process consists of several commercially proven unit operations. The base metals, are first selectively removed by use of a pressure oxidation step during which the dissolution of PGM is minimized. The residue from pressure oxidation is then subjected to a thermal treatment to ensure efficient PGM recovery by subsequent chlorination. The process uses much less energy than smelting and does not produce sulphur dioxide emissions, making it more environmentally responsible to install ”

Lifezone consultant, Dr. Mike Adams will be presenting the Kell Process at the Alta nickel conference on 30th May in Perth, and Keith Liddell will be presenting at the Global Platinum conference in Johannesburg on 6th June.

About The Company:

Lifezone Ltd. holds the exclusive rights to exploit the patents and technology for Kell process. Licensed by K.S. Liddell, the inventor of the Kell process, the company offers testing of concentrates at batch and pilot scale and engineering services for scoping and feasibility studies and design packages. Several smelting companies are evaluating the Kell process for selective extraction of valuable metals like Pt, Pd, Rh, Au, Ni, Co and Cu.
