Metallurgy is the science of metals and it has changed the way people live their lives. However, there are many issues involved with the extraction and processing of metals, from the initial removal of the ore from the ground to the production of the finished items. Some are purely environmental problems but others involve people too.

READ MOREExtracting Metal From Its Ore In Mining The ore grade, or concentration of an ore mineral or metal, as well as its form of occurrence, will directly affect the costs associated with mining the ore. The cost of extraction must thus be weighed against the metal value
READ MOREAn ore is a type of rock that contains minerals with important elements such as metals. Ores are extracted through mining they are then refined to extract the valuable element (s). The grade or concentration of an ore mineral or metal as well as its form of occurrence will directly affect the costs associated with mining it.
READ MOREThe process of extracting a metal in pure form from its ore is known as metallurgy. The process of treatment depends on upon the nature of the ore, impurities, and the metal. From the extraction point of view, the metals can be broadly classified into five categories.
READ MOREExtracting metals from their ores Rocks containing a considerable amount of a metal are called ores. The metal in the ore is present in its impure form as compounds of that element. These compounds are often metal oxides or metal sulphides.
READ MORE· For example, TPT''s latest assay results, dated 11 November 2013, from its Myanmar tungsten ore samples, produced 1,500% more gold yield than traditional methods. While only 34g of gold had been found per metric ton before the application of the RF plasma torch; the new technology uncovered an astonishing 500g of the precious metal for the same weight of complex ore.
