The first process in the extraction of zinc is the concentration. As shown in the diagram below, this process involves the implementation of froth floatation method for the extraction of zinc ores from zinc blende. Zinc blende is mixed up in a large tank consisting of a mixture of pine oil and water.

Of the more than 60 minerals that contain lead, only 3 galena, cerussite and anglesite are commercially viable. Usually, lead is found in conjuction with other metals such as silver and zinc. Lead materials are mined as a by product of these other more valuable metals. Extracting the lead materials from the ore is a multi step process.

The most important lead ore is galena (lead sulfide). Other important ores such as cerrusite (lead carbonate) and anglesite (lead sulfate) may be regarded as weathered products of galena and they are usually found nearer to the surface. Lead and zinc ores often occur together and for most extraction methods they have to be separated.

Lead Zinc Minerals The main oxidised ore minerals of lead are cerussite (PbCO3) and anglesite (PbSO4). Lead is one of the most widely used metals and over 60% of all lead
Flotation of Lead Ore. By far the most important lead mineral is the sulphide, galena. In many of the ores in which it occurs it is associated with sphalerite or marmatite, and two stage selective flotation is necessary to separate the two classes of minerals.
Compared to tin mining, the history of zinc mining is relatively short.In the 18th century, it was discovered that sphalerite, or zinc sulfide, could be smelted into brass, resulting in
Zinc is extracted from either zinc blende/sphalerite ore (zinc sulphide) or sometimes calamine/Smithsonite ore (zinc carbonate). (1) The zinc sulphide ore is roasted in air to give impure zinc oxide and forming the nasty poisonous gas sulfur dioxide (sulphur dioxide).
6.1.1 Lead and Zinc Ore Mining Lead and zinc ore is nearly always mined below the surface of the ground. Some veins of ore lie as deep as several thousand feet but most deposits lie close to the surface. Lead and zinc ore is mined almost exclusively in underground operations, though a few surface operations do exist.

Historically extraction of zinc has been more difficult than extraction of other metals because at temperatures where metals such as iron typically begins to melt, zinc is a gas. Due to its very low boiling point, at such temperatures, zinc will escape with exhaust gases.
Zinc is the 23 rd most abundant element in the earth's crust. Sphalerite, zinc sulfide, is and has been the principal ore mineral in the world. Zinc is necessary to modern living, and, in tonnage produced, stands fourth among all metals in world production being exceeded only by iron, aluminum, and copper.
ore is rich in oxide minerals, cerussite (PbCO 3) and smithsonite (ZnCO 3). The aim of the study was extraction of zinc from smithsonite by ammonia leaching on cerussite flotation tailings. Initial lead and zinc grades of the ore were 13.31% and 27.86%, respectively. As a
