In Nickel Flash Smelting technology, sulfide nickel concentrate is processed in the Outotec ® Flash Smelting Furnace to produce nickel matte and slag. The matte is transported to the Peirce-Smith converters where it is blown to high-grade matte.
Lead Sulfide Ore Lead & zinc metals are closely attached to each other and usually mined together from primary ore, for example, Galena (PbS) & sphalerite (ZnS) are associated in native ore. As the main formation of lead sulfide, galena is widely spread all over the world.
Nickel sulfide ores experience flotation and then contract smelted. Smelting a nickel sulfide flotation deliberate needs an MgO echelon of 6% otherwise the warmth at which the smelting will be scuttle at will be too towering and guide to superior operating prices.
Nickel is commonly present in two principal ore types – sulfide or laterite ores. Sulfide ores are typically derived from volcanic or hydrothermal processes and usually include copper (Cu) and/or cobalt,
