富含磁黄铁矿的铜镍硫化矿石的优先混合浮选现在从富硫化矿石中分离矿物的主要方法是优先浮选。含磁黄铁矿的硫化铜镍矿石的主矿物是黄铜矿、镍黄铁矿、磁黄铁矿，后者的品位为４０～６０％。这类矿石直接优先浮选，可以得到铜精矿、镍精矿、磁黄铁矿精矿与丢废尾矿。前两... Preferential mixed flotation of pyrrhotite-rich copper-nickel sulphide ores The main method of separating minerals from sulphide-enriched ores now is preferential flotation. The main minerals of the pyrrhotic copper sulphide nickel ores containing pyrrhotite are chalcopyrite, pentlandite and pyrrhotite, the latter of which have a grade of 40-60%. Direct flotation of such minerals directly, you can get copper concentrate, nickel concentrate, pyrrhotite concentrate and waste waste tailings. The first two ...
