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 0.09 6~0.07 5 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.
