Roasting is done for which ore :-
WebIn the Roasting process, the ores are heated with a regular supply of air in the furnace at a temperature below the melting point of the metal. This is done for Sulphide ores, in which Sulphide ore is heated to convert into oxides, and Sulphur dioxide gas is released. WebVideo transcript. let's talk about how to convert metal sulphides or metal carbonates to metal oxides in a previous video we talked about how to get pure metals from metal ores …

WebTherefore, the ore was subjected to a high-temperature reduction roasting process between 800 • C and 1000 • C. Additionally, the magnetic separation process was also employed. … WebThe roaster is a refractory-lined, upright cylindrical steel shell with a grate bottom through which air is blown in sufficient volume to keep fine, solid feed particles in suspension and give excellent gas-solid contact. The ore feed can be introduced dry or as a water suspension through a downpipe into the turbulent layer zone of the roaster.
WebOre roasting can be accomplished in many ways. The simplest way is to build a large wood fire on the ground or in a shallow pit and toss the ore on top. The problems with this are that it is near impossible to guarantee that everything gets well roasted and when you’re done you just have a pile of ore and ash that is difficult to separate. WebJun 11, 2024 · 1 Answer. Roasting removes easily oxidisable volatile impurities like aresenic (As2O3) ( A s 2 O 3), sulphur (as S O2 S O 2, phosphorus (as P 4O10) P 4 O 10) and antimony (as S b2O3) S b 2 O 3) . Organic matter moisture if present in the ore, also get expelled and the ore becomes porous.
