摘要
采用0.05％SnCl_2—20％HCl作方沿矿的选择溶剂,浸渣以浮选法选出黄铜精矿及黄铁矿的混合精矿产品,与脉石分离。然后进一步浮选混合精矿,分别选出黄铜矿、黄铁矿,并通过矿物量及其含金品位,计算出各种矿物中含金量。
adopting 0.05% of SnCl2 and 20% of HC1 as the selective solvent of galena dissolution, the combined concentrate products of chalcopyrite and pyrite were obtained from leaching residue by flotation process and then separated from gangue.After that, conduct flotation of the combined concentrate to produce chalcopyrite and pyrite and calculate the gold content of various minerals according to the amount of each mineral and the grade of gold content
