How is calcium extracted from its ore
WebFirst, the concentrated zinc blende is converted to its oxide (by roasting). After this, the oxide is reduced to zinc metal. The reactions for the two processes are: 1. Roasting: Zinc blende is subjected to roasting, i.e. it is heated in the presence of excess air. This converts zinc sulphide ore to zinc oxide. The reaction involved is: Web9 okt. 2024 · The process of extracting a metal by fusion of the oxide ore with a reducing agent is known as smelting. In this process, the roasted or calcined ore is mixed with suitable amount of coke (which acts as a reducing agent) and is heated to a high temperature above its melting point.
