Zinc is a very useful metal and used to plate iron and protect it from corrosion in a process known as galvanization Zinc also is used in many other alloys such as brass and solder An alloy of zinc and aluminum is nearly as strong as steel and as easy to mold as plastic4372
Zinc The important ores of Zinc are Zinc blende Z n S Calamine Z n C O 3 Zincite Z n O The extraction of zinc blende involves the following steps i Concentration The ore is crushed and then concentrated by frothfloatation process ii Roasting The concentrated ore is then roasted in the presence of excess of air at about 1200K4009
Zinc is found in the earths crust primarily as zinc sulfide ZnS Rarely is the ore as mined rich enough to be used directly by smelters it needs to be concentrated Zinc ores contain 515 zinc To concentrate the ore it is first crushed and then ground to enable optimal separation from4166
Roasting The concentrated ore is heated in a blast furnace at 900 o C where Zinc sulphide is converted to Zinc oxide Small amounts of ZnS may get oxidized to ZnSO 4 but above 900176 C ZnSO 44496
