Yunnan Copper Industry Co., Ltd. Is Now The Process Element Distribution Survey

In the paper, the investigative situation of the element distribution about the present process of Yunnan Copper Corporation Limited (YCC.Ltd) is introduced, and the detailed distributions of thirteen elements are clarified, respectively. When the modem Isasmelt process of YCC.Ltd will be put into produce, the former process, which is the blowing roasting and the electric furnace smelting, will be canceled. The paper, regarded as the valuable data that has accumulated the lot of experience and datum that YCC has achieved in the course of several decadal industrial production, will be preserved permanently.The paper regards the copper concentrates as the beginning of the investigation , by investigating and caculating the distributions of thirteen components, such as Cu, Fe, S, Si02, As, Pb, Zn, Bi, Sb, Ni, Co, Cd and Sn, in the total process of YCC including the blowing roasting, the electric furnace smelting, the converter blowing, the reverberatory refining and the electrolytic refining, and it finally acquires the distributive datum of the main element Cu and the other impure elements in all between or end products of the copper metallurgical processes, respectively. Then, by this paper, we will have a clear acquaintance with the remove impurities of the all copper metallurgical processes in the YCC.Basing on the datum of the investigation and the actual industrial production, the paper theoretically discusses the metallurgical actions that the Cu, Fe, S, SiO2, As, Pb, Zn, Bi, Sb, Ni, Co, Cd and Sn participate in the oxidation - reduction reactions in the processes of the copper metallurgy, respectively.
