| Abstract Scope |
In 2011, Glencore integrated an Albion Process™ direct leaching plant for the processing of bulk zinc / lead concentrate into the Nordenham Zinc Refinery Roast-Leach-Electrowin (RLE) flowsheet. The Albion Process™ is an atmospheric oxidative leaching process comprising mechanical and chemical liberation steps. Mechanical liberation is achieved by ultra-fine grinding of the concentrate which occurs at the mine site. Chemical liberation is achieved by sulphide oxidation through the supersonic injection of oxygen into a series of Albion Process™ leach reactors. The implementation of the Albion Process™ served two purposes: The first was to implement a process that could treat McArthur River Mine bulk zinc / lead concentrate at existing Glencore metallurgical assets. The second purpose was to overcome plant bottlenecks (roaster and acid plant) and fully utilize processing plant capacity. This paper describes the process that was implemented and the operating performance since 2011. |
