Zinc is a bh white, lustrous,ic metal, thoughmon commercial grades of the metal have a dull finish. It is somewhat less dense than iron and has a hexagonal crystal structure, with a distorted form of hexagonal close packing, in which each atom has six nearest neighbors at 265.9 pm in its own plane and six others at a greater distance of 290.6 pm. The metal is hard and brittle at most temperatures butes malleable between 100 and 150 °C. Above 210 °C, the metales brittl

Types of zinc ore Zinc ore occurs in two types of deposit: as primary zinc ore in thin veins known as rakes, or a secondary deposit formed by weathering of the primary mineral veins. Zinc ore ismonly found as zinc carbonate ZnCO 3, known as calamine or smithsonite.
The process of removal of unwanted material from the ore is known as concentration or dressing or benefaction of ores. It involves several steps. The separation of required material from the ore is dependent on the differences in physical properties ofpound of the metal present and that of the gangue. Gangue is an unwanted material which is a part of a mineral. The only useful material

Concentration of Ores. An ore of a metal is an impure source, this means other than the metal it consists of many other impurities such as sand, grit, clay, rocks etc. These impurities are collectively known as gangue. Gangue ismercial valueless and we must separate it from the ore. This entire process is the concentration of ores or even dressing or benefaction. Now there are

One process developed in Canada, and capable of recovering 99 of the zinc in the ore, uses pressures in excess of 10 atmospheres and a temperature of ca 420 K. The presence of iron in the ore concentrate is important in this method, as it is in part responsible for the conversion of zinc sulfide to zinc sulfate.
The percentage of zinc in the ore mined is frequently very low, and often averages 3 per cent., but this is increased by concentration. The Broken Hill district in New South Wales produces about 20 per cent, of the world's production in the form of concentrates, averaging from 40 to 45 per cent, metallic zinc.
a Ore concentration Lead and zinc ores usually sphalerite, ZnS often occur together and may also contain silver, copper and gold. The ore has first to be separated from clays and other silicates 'gangue' after which the lead ore and the zinc ore are separated.
