A Novel Approach to Processing of Australian Laterite Ores through Selective Reduction and Carbonylation

点击翻译按钮获取中文摘要

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.
