The metallurgical laboratory through the process of mineral identification shows, the ore is magnetite brass native copper ore, ore main copper minerals are chalcopyrite, bornite, chalcocite, tetrahedrite, followed by. Selected copper minerals are mainly disseminated in gangue minerals particle clearance, clearance and geode, most of coarse grain and in the aggregate form embedded in ore, micro hole only a handful of copper minerals are fine crystals embedded in the gangue minerals, or in the form of immiscible inclusion embedded in magnetite minerals.
According to the requirements of the mine, this test mainly for copper and copper mineral mineral mineral and other precious metals associated valuable detail, detailed experimental research. Through the contrast test conditions of various flotation technology and reagent condition, final flowsheet and reagent condition is reasonable, has achieved the ideal test index, achieved the purpose of the experiment.
This experiment obtained test indicators are as follows:
Ore grade: copper: 3.39% Gold: 1.06 grams / ton silver: 45.85 grams / ton
Copper concentrate grade:: 35.06% Gold: 9.68 grams / ton silver: 442.85 grams / ton
The recovery rate of copper concentrate:: 95.70%: 84.47%: 89.34% gold and silver
