Processing of laterite ores, started in 1998 in Australia, has significantly enhanced Australian role on the international nickel market. However, the production of nickel from oxide ores by established technologies consumes two to three times energy as processing of sulphide ores with significant environmental impact. This underlines the importance of development of more energy efficient processes for oxide ores. The proposed technology will significantly decrease energy and water consumption, and greenhouse gas emissions in nickel production. It will enhance the competitiveness of Australian Nickel Industry and stimulate its expansion with significant economy and social benefits.

澳大利亚于1998年开始加工红土矿，大大加强了澳大利亚在国际镍市场上的作用。然而，采用现有技术从氧化矿石中生产镍的能源消耗是加工硫化矿石的两到三倍，对环境造成重大影响。这强调了开发更节能的氧化矿石工艺的重要性。拟议的技术将大大减少镍生产中的能源和水消耗以及温室气体排放。这将提高澳大利亚镍工业的竞争力，促进其发展，具有显著的经济效益和社会效益。
