Question

Which furnace is used for roasting?

Answer 1

Hint: We have to know the method or study of working or warming metals to give them certain ideal shapes or properties. The strategy, or study of making and compounding composites. The procedure or study of isolating metals from their minerals.

Complete answer:
We have to know that roasting is an interaction of warming a sulfide mineral to a high temperature in the presence of air. It is a stage of the preparation of specific metals. All the more explicitly, broiling is a metallurgical interaction including gas strong responses at raised temperatures determined to refine the metal component(s). Regularly prior to cooking, the metal has effectively been part of the way refined, for example by foam buoyancy. The concentrate is blended in with different materials to work with the cycle. The innovation is valuable but on the other hand is a genuine wellspring of air contamination.
We have to know that roasting comprises warm gas-solid reactions, which can incorporate oxidation, decrease, chlorination, sulfation, and pyrohydrolysis. In cooking, the mineral or metal concentrate is treated with exceptionally hot air. This interaction is for the most part applied to sulfide minerals. During cooking, the sulfide is changed over to an oxide, and sulfur is delivered as sulfur dioxide, a gas. Hence, when the blast furnace is used for roasting. Blast heater, an upward shaft heater that produces fluid metals by the response of a progression of air brought under tension into the lower part of the heater with a combination of metallic metal, coke, and transition taken care of into the top.

Note:
We need to know that while calcination is generally utilized in the oxidation of carbonates, simmering is a technique that is utilized for changing over sulfide minerals. During roasting, dampness and non-metallic pollutants as unpredictable gases are delivered.
