A typical pyrometallurgical copper smelting process, as illustrated in Figure 12.3-1, includes 4 steps: roasting, smelting, concentrating, and fire refining. Ore concentration is roasted to reduce impurities, including sulfur, antimony, arsenic, and lead. The roasted product, calcine, serves as a dried and heated charge for the smelting furnace.

A major development in the world's platinum industry took place in the early nineteen twenties when large deposits of platinum bearing ore were discovered in the Transvaal in South Africa. This led to the formation in 1931 of Rustenburg Platinum Mines Limited to work these deposits, and this company remains to this day the only platinum producer in South Africa and the only …

Roasting: it involves heating of sulfide ore in the presence of an excess of air and below the melting point of the metal. 2 Cu 2 S + 3 O 2 → 2 Cu 2 O + 2 SO 2. 2 ZnS + 3 O 2 → 2 ZnO + 2 SO 2. c. Smelting: The extraction of metal from its molten state is known as smelting.

Stainless steel crude alloy recovery from direct smelting of low-grade chromite, nickel laterite and manganese ores was investigated. The mixed low-grade ores were directly smelted in an elevator furnace at smelting temperatures ranging from 1550 to 1600 °C. Smelting experiments were conducted in a laboratory elevator furnace equipped with 8 U …

Ferroalloys DC Smelting Plant. Outotec's direct current (DC) smelting furnace can be used for direct smelting of fine ores, even those with highly variable chemical or mineralogical compositions, as well as for recycling challenging by-products such as steel dust. Use a cost-efficient, sustainable, and compact solution for ferroalloys ...

A credit of the market value for the 2.5 to 3.0 tons of blast furnace slag produced on smelting the crude ore would lower the net cost of the iron product somewhat. Then an additional credit would be realized if the ore were smelted at the Lower Lake ports, the saving being the difference between $6.97 and $3.42 shipment costs for 3.10 tons of ...

copper processing - copper processing - Roasting, smelting, and converting: Once a concentrate has been produced containing copper and other metals of value (such as gold and silver), the next step is to remove impurity elements. In older processes the concentrate, containing between 5 and 10 percent water, is first roasted in a cylindrical, refractory-lined …

equipment used in lting crude metal or ores. Smelting - Wikipedia Smelting is a process of applying heat to ore in order to extract a base metal.It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off …

12%The mixed low-grade ores were directly smelted in an elevator furnace at smelting temperatures ranging from 1550 to 1600 °C. Smelting experiments were conducted in a laboratory elevator furnace equipped with 8 U-shaped high-quality molybdenum disilicide heating elements. A low-grade coal was used as the reductant.

Nickel: smelting; Extraction and purification; Nickel is recovered through extractive metallurgy: it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity. In many stainless steel applications, 75% pure nickel can be used without further purification, depending on the composition of the impurities.

in the metallurgy of nonferrous metals, the electric smelting furnace has had a greater application for the treatment of zinc ores than in the metallurgy of any of the other nonferrous metals except aluminum the process has not been applied to any great extent because of the difficulty of condensing the zinc vapor produced in smelting in the …

Smelting sulfide ores can be accomplished in a reverberatory, flash, or electric smelting furnace. Modern technology uses flash smelting or electric smelting. Flash smelting is the most common process but electric smelting is used for more complex raw materials when increased flexibility is needed. Both processes use dried concentrates.

Smelting is the process by which a metal is obtained either as an element or as a simple compound, from its ore by heating beyond the melting point with the presence of oxidizing agents such as flux. In other words, smelting is the process of applying heat to ore in …
