Processing of Nickel Laterite Ores on the Rise

Once ore has been dried, it is processed in a large-scale rotary kiln to remove chemically bound moisture, as well as the oxide component of the ore. This step is often referred to as pre-reduction. Reduction & Smelting. Nickel is further reduced and smelted in an electric furnace.


Smelting produces lead by melting and separating the lead from metal and nonmetallic contaminants and by reducing oxides to elemental lead. Smelting is carried out in blast (SCC# 3-04-004-03), reverberatory (SCC# 3-04-004-02), and rotary kiln (SCC# 3-04-004-99) furnaces. Blast furnaces produce hard or antimonial lead containing about 10 percent
