| Abstract: | The main mineral components of a copper ore from Qinghai province were analyzed.In view of the valuable minerals in the copper ore being chalcopyrite and chalmersite and most copper existing in primary minerals,exploratory flotation experiments on species of collector,separation of copper and sulfur,as well as closed circuit flow-sheet experiment were carried out.The optimal separation flow-sheet and reagent system were determined.A copper concentrate with copper grade of 17.41% and a recovery rate of 88.88... |
