網頁askIITians Faculty 1246 Points. Silica (SiO2) is used in the processes of smelting of copper pyrite (CuFeS2) ore and in conversion of produced copper matte (refined copper sulfide) into a crude metal as a flux (purifying agent). It reacts with solid impurities, such as iron oxide, and forms a liquid slag with density, smaller than the copper matte. 網頁1 天前 · Copper Solvent Extraction Reagent Market Size (sales, revenue) forecast by regions and countries from 2024 to 2029 of Copper Solvent Extraction Reagent industry.The detailed information is based ...
