石菉铜矿是我国唯一采用离析—浮选工艺处理难选氧化铜矿的选厂。自1976年正式投产以来,主要技术经济指标不断提高,1983年原矿含铜2.79％,采用离析—浮选法可获铜精矿品位26.75％,回收率78.00％,生产正常。由于矿石性质变化,热能消耗高,加之能源日趋短缺和价格上涨,生产成本高,1980年以来,我所对石菉铜矿原矿性质和加工工艺进行大量考查和研究工作,提出在离析—浮选工艺的基础上,将原矿中+4毫米粒级筛出(约占原矿重量的30％),不进
Stone green copper mine is the only use of separation - flotation process refractory copper oxide ore processing plant. Since its formal operation in 1976, the major technical and economic indicators have been continuously raised. In 1983, ore contained 2.79% copper. The grade of copper concentrates was 26.75% by recovery-flotation, with a recovery of 78.00%. Production was normal. Due to the change of ore properties, high heat energy consumption, coupled with the growing shortage of energy and rising prices, the production cost is high. Since 1980, a large number of tests and studies have been conducted on the nature and processing technology of the raw stone- On the basis of technology, the original ore +4 mm particle size sieve (about 30% of ore weight), do not enter
