Iron Ore Smelting Process Using Modern Blast Furnaces. Viraf J Dalal Chemistry Class 10 Solutions and Answers. In metallurgy refining of metals is the final process. The notably greater yield obtained by heating native copper with associated oxide minerals may have led to the smelting process, since these oxides are easily reduced to metal in a charcoal bed at temperatures in excess of 700 °C (1,300 °F), as the reductant, carbon monoxide, becomes increasingly stable. CL provides CBSE Biology prep material for class 10 students. To many, SLM is considered to be a subcategory of selective laser sintering (). Answered Explain the breathing process in man.
