目前有很多不用氰化物分离铅-铜精矿的方法,用高锰酸钾抑制黄铜矿是其中之一。用高锰酸钾分离铅-铜精矿的试验是用不同矿床的矿石进行的。表1所列举的分离铅-铜精矿的数据是由两个多金属选矿厂(A和Б)的试验室得来的。用于进行一次分离试验的混合铅-铜精矿矿浆,是试验前从浮选槽中直接取出来的。试验是在容积为4立升和1立升《米哈诺布尔》型的试验室浮选机内进行的。用高锰
There are many ways to separate lead-copper concentrates without cyanide, one of which is the inhibition of chalcopyrite with potassium permanganate. The test of separating lead-copper concentrates with potassium permanganate was carried out using ore from different deposits. The data for the separation of lead-copper concentrates listed in Table 1 were obtained from the laboratories of two polymetallic concentrates (A and B). The mixed lead-copper concentrate slurry used for a separation test was taken directly from the flotation cell prior to the test. The test was carried out in a laboratory flotation machine of 4 liters in volume and 1 liters of “Michaelabell” type. With high manganese
