Roasting (metallurgy)

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.


K.G. Thomas, A.P. Cole, in Gold Ore Processing (Second Edition), 2016 Abstract. Roasting of ores and concentrates can be defined as the heating of a material to cause reaction and the expelling of volatile matter without causing fusion. Oxidative roasting is used extensively to pretreat base and precious metal–bearing materials and to oxidize iron sulfides to generate sulfur dioxide for ...

Metallurgy | Article about metallurgy by The Free Dictionary

The flux used depends upon the chemical nature of the ore; limestone is usually employed with a siliceous gangue. A sulfide ore is commonly roasted, i.e., heated in air. The metal of the ore combines with oxygen of the air to form an oxide, and the sulfur of the ore also combines with oxygen to form sulfur dioxide, which, being a gas, passes off.

What Is Sulfur Powder Used For? | Hunker

Most plants prefer soils of pH range between 5.8 and 7.0. Some plants such as azaleas, gardenias and blueberries prefer a more acidic soil. Soils in limestone regions may have a pH as much as 8.0 and consist of 50 percent lime. Such alkaline soils induce deficiencies in iron, zinc and manganese. Leafy plants may become yellow in these conditions.

by products of iron extraction

Waste gases produced by the blast furnace Carbon monoxide (CO)and carbon dioxide (CO2). When using iron sulfide (FeS2, pyrite) as the iron ore, sulfur dioxide (SO2)may also be produced as a waste gas. Carbon dioxide emissions increase the greenhouse effect, whereas sulfur dioxide is a pollutant and contributor to acid rain.

Limestone for Sulfur Removal

Sulfur dioxide has a direct impact on human health and is responsible for a variety of respiratory problems (Table 4.10).Like most air pollutants, sulfur dioxide poses a greater threat to sensitive groups such as the elderly, asthmatics, and young children. By contributing to acid rain, sulfur dioxide can have significant impacts on plants, surface waters, and buildings.
