稀有金属铼主要伴生在钼矿或铜钼矿中,它没有单独的矿床。我国大型钼矿如峦川矿、金堆城矿、杨家杖子矿等含铼量较低(钼精矿中含铼十万分之几)。湖南宝山钼矿中含铼量相对较高(钼精矿中含铼万分之五左右)。从该矿中提铼有显著的经济效益。 钼精矿焙烧的方法不同,铼富集的程度也不同。采用燃煤加热法,铼富集在烟道里,杂质较多。采用重油加热,铼富集在静电除尘器和旋风除尘器中,富铼烟尘杂质较少。采用电
Rare metal rhenium is mainly associated with molybdenum ore or copper molybdenum ore, it does not have a separate deposit. Large molybdenum mine in China such as Luanchuan mine, Jinduicheng mine, Yangzhangzizi mine and other low rhenium content (molybdenum concentrate containing rhenium ten thousandths). The content of rhenium in Baoshan molybdenum mine in Hunan is relatively high (molybdenum concentrate contains about five ten thousandths of rhenium). Rhenium from the mine has significant economic benefits. Different methods of roasting molybdenum concentrate, rhenium enrichment is also different. The use of coal heating method, rhenium enrichment in the flue, more impurities. Heavy oil heating, rhenium enrichment in electrostatic precipitators and cyclones, rhenium-rich dust less impurities.
