摘要
哈海岗铜多金属矿床Ⅱ号矿体的有用组分为铁、铜、铅、锌、钨,Ⅳ号和Ⅲ号矿体有用组分为铁、钨、钼。该矿床的主要金属矿物为磁黄铁矿、闪锌矿、方铅矿、磁铁矿、黄铜矿、黄铁矿、白钨矿、辉钼矿。矿石破碎后,>0.25 mm粒级的有用元素产率最大(>50%),其次是<0.075 mm粒级(>19%),其他粒级的有用元素产率较少,特别是0.096～0.075 mm粒级,有用元素产率仅为1%。在各个粒级中铁、铜、铅、锌、钼等元素的品位变化不大,仅钨在Ⅲ矿体中细粒级品位高于粗粒级品位近2倍。
No.Ⅱore useful components in copper-polymetallic ore of Hahaigang are iron,copper,lead,zinc and tungsten.No.Ⅲ and No.Ⅳ ores useful components are iron,tungsten and molybdenum.The main metal minerals are pyrrhotite,sphalerite,galena,magnetite,chalcopyrite,pyrite,scheelite and molybdenite.The useful elements of broken ore 0.25 mm particle-level have maximum yield,followed by 0.075 mm particle-level.Other particle-level grain size is 0.096-0.075 mm,only 1%.Iron,copper,lead,zinc,molybdenum and other elements change little in grain size.Only tungsten fine grade is 2 times bigger than coarse-level grade in Ⅲ ore body.
