The Dongshengmiao deposit is located in the Langshan district, which is at the northern margin of the North China Craton (NCC) and borders the Central Asian Orogenic Belt (CAOB) to the north (Fig. 1).This district hosts three significant Cu-Pb-Zn polymetallic deposits, including Huogeqi, Jiashengpan, and Dongshengmiao, and …
The final stage in iron ore processing is ironmaking, where the iron ore is transformed into molten iron through a process called reduction. The most common method of ironmaking is the blast furnace route. In a blast furnace, iron ore, coke (carbon), and fluxes (limestone or dolomite) are loaded into the furnace from the top.
However, it is unclear whether the conventional approach for Cu-Zn and Cu-Zn-Pb ores (i.e., depression of sphalerite using zinc sulfate) is effective in Cu/Zn separation in the processing of the copper ores excavated from PCDs with a much lower level of Zn (e.g., a Cu/Zn ratio of 7:1 (w / w)) compared to Cu-Zn or Cu-Zn-Pb sulfide ores . Thus ...
