After that mercury oxide is reduced to obtain mercury. The following reactions are involved in this process. 2HgS 3O2 ⇨ 2HgO 2SO2. Extraction of metals of medium reactivity series The metals in the middle of the reactivity series are also extracted by roasting followed by reduction but the methods are somewhat different.
Give the steps involved in the extraction of metals of low and medium reactivity from tror respective sulphide ores Geografi. Answer #1 . Answer we can extract the metal from sulphide ore by a process of roasting (heating in the presence of oxygen) to form it s oxide and then we get metal by further heating it s oxide in absence of oxygen .
