Results of investigations of concentration of metallurgical slag using electrical separators, jugs and flotation machines, sluices, concentration table, and Itomack centrifugal separator are presented. As a result, two production flowsheets are suggested, wet and dry, which provide recovery of ∼95% silver and ∼89% gold mixed with a ∼15.5% metal content.

The metal temperature is the most important factor to determine a controlled level of the slag in the furnace. If the metal temperature exceeds 780 oC, the rate of formation of slag increases dramatically, as shown in Figure 2.

A. Slag is the glass-like by-product left over after a desired metal has been separated from its raw ore. While slags are generally used to remove waste in metal smelting, they can also serve other purposes, such as assisting in the temperature control of the smelting, and minimizing any re-oxidation of the final liquid metal product before the molten metal is removed from the furnace and used

Slag is also called molten slag. The melt that floats on the surface of liquid substances such as metals during the pyrometallurgical process is composed mainly of oxides (silicon dioxide, aluminum oxide, calcium oxide, magnesium oxide), and often contains sulfides and a small amount of metal.

An environmental technology to extract the titanium components and metallic iron from the slag is necessary. Many methods are applied to extract the titanium from Ti-bearing blast furnace slag, such as acid leaching, fused salt chlorination, high-temperature modification (HTM), preparing alloy process, etc. [4–8].

In this study, mathematical model of vanadium transfer from metal to slag was formulated and the rates of vanadium extraction of hot metal with basic slag were investigated. The results indicated that the apparent vanadium extraction rate constant, k p , were in the range of 1.33∼9.07×10– 4 g/ (cm 3 ·s).
