The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes known as tuyeres.
Extracting iron from the ore. Think about: Loss of landscape due to the size of the chemical plant needed. Noise. Atmospheric pollution from the various stages of extraction. For example: carbon dioxide (greenhouse effect); carbon monoxide (poisonous); sulfur dioxide from the sulfur content of the ores (poisonous, acid rain).
Bioleaching is the extraction of metals from their ores through the use of living organisms.This is much cleaner than the traditional heap leaching using cyanide. Bioleaching is one of several applications within biohydrometallurgy and several methods are used to recover copper, zinc, lead, arsenic, antimony, nickel, molybdenum, gold, silver, and cobalt

In its pure form or as an alloy, copper (Cu) is one of the most important metals in society. The pure metal has a face-centred cubic crystal structure, and ...
Extraction of ore from the deposit Processing of ore to produce metal or mineral products Producing steel and other alloys Producing wire, coil, ... •The ROM is processed via numerous stages of gravity concentration, magnetic separation and electrostatic separation.
Copper mines are only set up where there is more than 5kg of copper per tonne of rock (0.5% by mass). Ideally, the figure should be closer to 2%. The flow chart shows you how copper is extracted from its ore and converted into pure metal.
Uranium Solvent Extraction Mixer Tank showing airlift transfer of solvent between stages. Steel shavings are added to the liquor in a 5′ x 10′ tank with a false bottom, to reduce all ferric sulphate to ferrous sulphate with an EMF of 275 to 300 desired.
Rare Metal Extraction by Chemical Engineering Techniques describes the use of chemical engineering techniques in the extraction and purification of rare metals such as uranium, thorium, and zirconium as well as hafnium, titanium, beryllium, and vanadium. The various chemical extraction stages from ore to metal are discussed.
Aluminum is the most abundant metal in the earth’s crust and is a constituent of many minerals. However, the material which is highest in aluminum and most free from objectionable impurities is bauxite which, therefore, is practically the only source of the metal under present processes. Bauxite is the general name given to the hydrated oxides of aluminum.
3. Copper sulfate solution is collected in the pregnant leach pond then pumped to the solvent extraction plant. The solvent extraction phase of treatment occurs in two stages. During the initial phase an organic solvent is used to recover copper ions contained in the pregnant leach solution, exchanging them with hydrogen ions in the acid.
Extraction of tin consists of three parts, i.e. tin ore concentration, smelting and refining. Cassiterite is the main source of tin ore, with specific gravity of 6.8-7g/cm 3, density larger than most of gangue.Therefore, 90% of tin concentrate is mainly obtained from cassiterite through gravity separation.
