At the peak of operation, approximately 300 people worked in the mill town and in the mines.Determination of fluorine in copper ore using laserThe widely applied copper metal is mainly produced by smelting copper ore, in which fluorine (F) is one of the harmful elements. Therefore, the F content has become a mandatory test index for copper ore. The low excitation efficiency, complex and serious spectral interference makes it difficult to detect F eMine TailingsMine tailings are the finely ground residue from ore extraction. The grain size of the tailings depends on the nature of the ore and the milling process. Size measurements (Robertson, 1994) of tailings from four mines in Ontario, Canada, indicated the tailings materials to be predominantly silt and fine to medium sand with <10% clay content.OperationOperation.
