Roasting (metallurgy) - Wikipedia

Roasting is a process of heating a sulfide ore to a high temperature in presence of air. It is a step of the processing of certain ores.More specifically, roasting is a metallurgical process involving gas–solid reactions at elevated temperatures with the goal of purifying the metal component(s). Often before roasting, the ore has already been partially purified, e.g. by froth flotation.

Iron ore - Wikipedia

Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)n(H 2 O), 55% Fe) or siderite (FeCO ...

Iron ore - Wikipedia

Ores containing very high quantities of hematite or magnetite (greater than about 60% iron) are known as "natural ore" or "direct shipping ore", meaning they can be fed directly into iron-making blast furnaces.Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel.

Pyrite roasting, an alternative to J sulphur burning

The roasting of sulphide ores and concentrates is often the first step in the production of metals or chemicals. In many processes, the production of sulphuric acid is viewed as a by-product, whereas in some plants production is an important economic factor. Regardless of the purpose, a pyrite roasting plant consists of mainly three plant

Rotary kiln - Wikipedia

A rotary kiln is a pyroprocessing device used to raise materials to a high temperature (calcination) in a continuous process.Materials produced using rotary kilns include: Cement; Lime; Refractories; Metakaolin; Titanium dioxide; Alumina; Vermiculite; Iron ore pellets; They are also used for roasting a wide variety of sulfide ores prior to metal extraction.

Zinc processing Britannica

Zinc processing, the extraction of zinc from its ores and the preparation of zinc metal or chemical compounds for use in various products.. Zinc (Zn) is a metallic element of hexagonal close-packed (hcp) crystal structure and a density of 7.13 grams per cubic centimetre. It has only moderate hardness and can be made ductile and easily worked at temperatures slightly above the ambient.

iron. Even now mine operators are mixing lean ores with rich ores to hold the grade to about 51 percent and conserve the high-grade deposits. Obviously, when the grade of iron ore produced falls under this figure there will be an increase in the price of pig iron and a corresponding industrial readjustment in price for all finished iron products.

The carbonate ores require calcining (roasting) to drive off carbon dioxide, converting the ore into a oxide before it can be smelted to produce iron or steel. Calcining also improves the ore for smelting by driving off water and other volatile substances, and by breaking the ore into smaller fragments.
