359 g of powdered lead sulfide and 27 g of granulated aluminum are mixed together. The mixture is transferred in the clay crucible, which is covered and placed in the gas furnace. The furnace is heated as rapidly as possible and the beginning of the reaction is indicated by appearing of a white puff of smoke.

17/02/2018· Lead smelting uses heat and chemical reactions to free lead from the compounds it is bound to in lead ores. The mineral galena — lead sulfide (PbS) — is one of the primary ores used in the smelting process. First, the lead is oxidized, releasing it from the sulfur and binding it to oxygen, forming lead oxide (PbO).

There are two ways in which galena can be transformed into lead and each process requires two chemical reactions to occur in the furnace: Process #1 1) 2PbS + 3O2 → 2PbO + 2SO 2 In the first reaction of the first process, galena is roasted in order to remove the sulfur component of the metal sulfide.

Zinc. Zinc is often found in nature together with lead in sulfide ores. The metals are separated during refining. As zinc is resistant to corrosion and easy to apply, much of it is used to protect iron and steelbased products. Uses of zinc. Zinc is used as coating to protect iron and steel from corroding in the atmosphere, water and soil.
