Mining and Ore Processing Mercury Pollution Estimated Population at Risk Million Description Mining and ore processing occurs throughout the world and consists of extracting minerals metals and gems from surrounding earth and ore
intensity of minerals and ore deposits The skarn type hydrothermal deposits are found in the depths of such systems This model describes in particular geological and hydrogeothermal situation which existed in the areas of Apennine Peninsula Larderello Monte Amiata geothermal region and California Cordillera Geyzers Clear Lake
Hydrothermal process is the most common ore forming process Water is heated by the magma chamber and this water dissolves metals Metals are dissolved in the water and this solution seeps through cracks fractures and through permeable rocks until they are precipitated and form a deposit There are three types of water sources
ore formation is a common and intrinsic part of crustal evolution large and super large ore deposits require the coincidence of particularly favourable combinations of processes and source parameters
Crystallization of Magma The minerals that make up igneous rocks crystallize at a range of different temperatures This explains why a cooling magma can have some crystals within it and yet remain predominantly liquid
