Lithium was first discovered in the mineral petalite Lepidolite and spodumene are other common minerals which contain lithium Commercial quantities of these three minerals are in a special igneous rock deposit that geologists call pegmatite In pegmatites magma cools so slowly that crystals have time to grow very large Because lepidolite is a type of mica its crystals grow into long thin

minerals in thin section quartz white light passes unaffected through the mineral and none of its wavelengths is absorbed whereas with opaque minerals such as metallic ores all wavelengths are absorbed and the minerals appear black With colored minerals selective absorption of wavelengths takes place and the colour seen represents a combination of wavelengths of light transmitted

ORE DRESSING ORE DRESSING Ore dressing is the treatment of ores and mineral products by mechanical physical or chemical means to separate the valuable minerals from the worthless constituents to increase its concentration CRUSHED ORE ENRICHMENT PROCESS CONCENTRATE TAILINGS ORE DRESSING METHODS 1 Hand Picking 2 Separating minerals by utilizing hardness

The metal ore mining market consists of the production of metal ores and concentrates by entities that mine metallic mineral ores The industry includes establishments developing mine sites ore dressing and other beneficiating operations such as crushing grinding washing drying sintering concentrating calcining and leaching The use of robots in the metal ore mining industry is

Liberation of valuable mineral by size reduction technologies In most ores the valuable minerals is distributed in the matrix of ore 2 Concentration technologies to separate the gangue minerals and to achieve increase in the content of the valuable mineral to increase the metal grade

The first stage in ore dressing or mineral beneficiation is comminution or size reduction in order to liberate valuable minerals from the gangue Information on the size and intergrowth relationship textures of minerals is of great importance from this point of view The optimum grain size for effective liberation can only be determined by a careful examination of ore textures in polished

 · Then the minerals need to be separated out of the ore; Since most minerals are not pure metals further separation methods are required Most minerals are chemical compounds that contain metals and other elements Concentration After mining large pieces of the ore feed are broken through crushing and/or grinding This step creates particles that are either mostly valuable or mostly waste

 · Tungsten minerals in this ore occur both as distinct liberated mineral phases and as composites viz ultrafine dissemination of wolframite in scheelite and vice versa Cassiterite also has similar characteristics albeit to a lesser extent with few grains containing ex solution intergrowth of columbite/tantalite and very fine dissemination of tungsten minerals in its lattice The complex

 · For the separation of iron ore the author suggests that it is better to customize the appropriate dressing methods of minerals instead of applying the method of mineral processing arbitrarily Fote heavy industry as one of China s mining industry leaders has always been to provide clients with the best production equipment and design the most suitable ore dressing solutions

 · Deeply weathered zones especially those at the top of metal rich rocks and ore bodies produce many different oxides and hydrated minerals with strong colors The most common blue/bluish minerals of this type include azurite chalcanthite chrysocolla linarite opal smithsonite turquoise and vivianite Most people will not find these in the field but any decent rock shop will have them all

In many cases the valuable minerals are mixed with gangue commercially useless material and the ore must be separated The first step of many separation processes is comminution size reduction followed by classification separation by particle size either for further grinding or the next step concentration of the ore

Process Metallurgy is the oldest area of metallurgy which encompasses ore dressing to pyro hydro and electro metallurgy Over the years several technological advances have taken place in these fields However with the demand for more tonnage of metals economical extraction of metals in an environmental friendly way from lean and complex ores has challenged the traditional way of extraction
