Ores of metals like silver and gold are mixed with common salt and are heated in air. Roasting is a process of heating of sulphide ore to a high temperature in presence of air. / 8gKcuOyg7V+Kpr3FMxW97N5F8w6JH5Ztra91GCG9R7qSe2uZ4lnX9/LIxdWKGoX4mNBtmVjkKaZg Hxe+ZA0GEfwtJ1uXvS3/AAHd/wDLVH/wLZrf5dh/NLm/yRL+c7/Ad3/y1R/8C2P8uw/mlf5Il/Od A solution of a salt of the metal serves as the electrolyte. 2aQqAU+Bqg9z/k4+ITsvABuz3Sfyx8q6XqFreW0cjT2gqglcOhcVpKykfa3240AIFN8sGMAtZmSx BPSC Prelims and Mains Notes, BPSC Test Series, Metallurgy concentration, roasting, smelting.
