Hydromet Technology. Hydrometallurgy, or "hydromet" for short, is a metal processing technology that uses a chemical process combining water, oxygen or other substances in a pressurized or other vessel to dissolve a metal from its ore, concentrate or an intermediate product (such as matte). The nickel industry worldwide has traditionally ...

3. EAF dust treatment process The existing dust treatment plants are classified to two groups, namely 1) solid reduction process and 2) smelting reduction process. Both processes reduce zinc oxide in the dust to zinc vapor to separate it from the residue. Solid reduction process does not melt the iron oxide, and partially reduce it to FeO. On ...

used to produce a matte (40 – 50 wt % Cu) and a disposal slag (ca. wt % Cu). In contrast, oxide ores are processed directly to impure black copper ( 95 wt % Cu) and to a copperrich slag. The two ore types can be smelted together to produce matte and a slag with low copper content. Another product is top gas, which contains flue dust ...

· The production of slags with higher TiO 2 content from rock ilmenite is very difficult, due to the relatively high impurity content of the raw material. Therefore, slag produced from rock ilmenite is mostly sold to TiO 2 pigment producers that use the Sulfate process, hence the name "sulfate slag." Sulfate slag cannot be used in fluid bed chlorination because it .

Copper smelting is a 3 stage process. First the iron is removed by heating the ore with silica. The iron is oxidised and reacts with the silica to form a slag, which can be drawn off separately. Next the remaining copper sulfide is heated to a higher temperature and air blown through to burn off the sulfur which forms sulfur dioxide.

A summary of production steps from the bauxite mine through casting is given in Fig. Bauxite mining Aluminum comprises approximately 8% of the earth's crust, making it second only to silicon (%). Iron is third at about 5%. Metallic aluminum is not found in nature; it occurs in the form of hydrated oxides or silies (clays).

Hot calcine is fed to an electric furnace (Figure 1b) where the remaining Fe 3 O 4 is reduced to FeO and the NiO and CoO, together with part of the FeO, are reduced to molten ferronickel. The gangue oxides form slag. Finally, the molten ferronickel is refined ...

submerged arc process is a reduction smelting operation. The reactants consist of metallic ores (ferrous oxides, silicon oxides, manganese oxides, chrome oxides, etc.) and a carbonsource reducing agent, usually in the form of coke, charcoal, high and lowvolatility coal, or wood chips. Limestone may also be added as a flux material. Raw materials are crushed, sized, and, in .
