In 2002, the major achievements of the non-ferrous metals industry in scientific and technological progress include: (1) A major breakthrough was made in the research on the production of sand-like alumina: the development and application of laboratory sand-like alumina additives were completed and the sintering process was completed ahead of schedule Carbon production of sand alumina technology semi-industrial test, the process has its originality and independent intellectual property rights. Laboratory tests and semi-industrial test results have reached the key technical requirements for research and production to meet the requirements of the sand-like alumina; (2) the use of pulp electrolysis of complex antimony lead ore, antimony and lead can be achieved in one step separation and metal Antimony step extraction, has a good industrialization prospects. The research result is a new breakthrough in the innovation of antimony smelting technology and the application of slurry electrolysis technology, and applied for the invention patent. (3) The technology of “low pressure and pressure leaching-extraction-electrowinning”
