江西省科委向赣州钴冶烁厂下达的从含钪炉渣中提取氧化钪的研究项目,由省冶金厅主持,于1989年12月20日在赣州市通过省级监定。赣州钴冶炼厂的黑钨精矿采用经典流程生产仲钨酸铵,每年产出约1200吨钨碱渣。钨碱渣含有钨、钪、锰、铁等有价金属和极少量的放射性元素,属于极低放射性废渣。为了变废为宝,钨碱渣通过电炉还原熔炼制取钨铁合金。而钪、
Jiangxi Province Science and Technology Commission to the Ganzhou cobalt smelting plant issued from the scandium scandium oxide scandium extraction project, presided over by the Provincial Department of Metallurgy, December 20, 1989 in Ganzhou City, through provincial-level monitoring. The tungsten tungsten concentrate of Ganzhou cobalt smelter uses the classic process to produce ammonium paratungstate, which produces about 1200 tons of tungsten alkali-caustic soda annually. Tungsten slag contains tungsten, scandium, manganese, iron and other valuable metals and a very small amount of radioactive elements, are very low radioactive waste. In order to turn waste into treasure, tungsten soda slag through reduction furnace smelting tungsten alloy. Scandium,
