雷坪有色金属矿是个小型铜矿山,历年来,铜精矿含铜仅有14～15％、含砷高达4～5％,我们采取了一些措施,使铜精矿品位达到21％以上,含砷降至0.35％以下。雷坪矿床属于碳酸盐岩交代和充填的含铜多金属矿床。黄铜矿呈浸染状、细脉状和星点状分布于
Lei Ping Nonferrous Metal Mine is a small copper mine. Over the years, the copper concentrate has only 14-15% copper and 4-5% arsenic. We have taken some measures to achieve a copper concentrate grade above 21% Arsenic dropped to 0.35% or less. The Lei Ping deposit belongs to the copper-bearing polymetallic deposit that was exchanged and filled by carbonate rocks. Chalcopyrite was disseminated, fine veins and star-shaped distribution in
