I know that sulphide ore are roasted while carbonate ore are calcinated.
What will happen if we roast carbonate ore and calcinated sulphide ore?
What will happen if we roast carbonate ore and calcinated sulphide ore?
Roasting and calcination are both thermal processes used to remove impurities from a substance. Roasting involves heating a substance in the presence of oxygen, while calcination involves heating a substance in the absence of oxygen.
Roasting is commonly used for ores and sulfide compounds, while calcination is commonly used for carbonate compounds and organic materials.
The main purpose of roasting and calcination is to remove impurities from a substance and to transform it into a more useful form. This can include removing sulfur from ores or converting calcium carbonate into calcium oxide.
The main factors that affect roasting and calcination are temperature, duration of heating, and the presence or absence of oxygen. The type of substance being heated can also play a role in the process.
Roasting and calcination have various industrial applications, such as in the production of metals, cement, and chemicals. They are also commonly used in the production of food and pharmaceuticals, as well as in environmental processes for waste treatment and air pollution control.
