    Development of Smelting Reduction Processes for Ironmaking

    6.1.2.4 Lead Concentrate Sintering and Smelting Smelting is the process by which rough lead bullion is produced from lead concentrate. After the ore has been concentrated at a mill near the mine, the lead concentrates are shipped to a smelter. Here, in the case of galena, the first step involves removing the sulfur from the mineral. Roasting.When smelting with self-fluxing ore, since the ore contains more CaO and it can be in good contact with acidic SiO2, CaO immediately participates in the slagging reaction at the beginning of smelting, especially when self-fluxing sintering is used. During ore smelting, CaO and SiO2 and Al2O3 formed slag early in the sintering process.

    Lead and Zinc Sintering IntechOpen. 2020-3-26 Difference Between Melting and Smelting Definition. Melting Melting is the process by which a substance changes from the solid phase to the liquid phase. Smelting Smelting is the process by which a metal is obtained at temperatures beyond the melting point from its ore. Temperature. Get price.The sintering process takes place in furnaces that cool materials at a rate consistent with the creation of martensitic, crystalline structures. At first, discrete particles remain because complete compaction or melting does not occur. In powder metallurgy, the selected sintering temperature is always lower than the melting point of the primary ...
