Vein and disseminated tin deposits are mined by the same methods used in hardrock mining of other nonferrous ores such as zinc The ore is broken by drilling and blasting transported to a concentrator where it is crushed and ground and then concentrated by gravity methods The concentrate is usually of a lower grade Vein and disseminated tin deposits are mined by the same methods used in hardrock mining of other nonferrous ores such as zinc The ore is broken by drilling and blasting transported to a concentrator where it is crushed and ground and then concentrated by gravity methods The concentrate is usually of a lower grade

The Earth 39s crust contains metals and metal compounds such as gold iron oxide and aluminium oxide but when found in the Earth these are often mixed with other substances To become over time For example as a metal becomes rarer an ore may be used when it was previously considered too expensive to mine The Earth 39s crust contains metals and metal compounds such as gold iron oxide and aluminium oxide but when found in the Earth these are often mixed with other substances To become over time For example as a metal becomes rarer an ore may be used when it was previously considered too expensive to mine

There are nine tinbearing ores found naturally in the earth 39s crust but the only one that is mined to any extent is cassiterite In addition to the ores themselves several other materials are often used to process and refine tin These include limestone silica and salt Carbon in the form of coal or fuel oil is also used There are nine tinbearing ores found naturally in the earth 39s crust but the only one that is mined to any extent is cassiterite In addition to the ores themselves several other materials are often used to process and refine tin These include limestone silica and salt Carbon in the form of coal or fuel oil is also used

Insitu mining which is primarily used in mining uranium involves dissolving the mineral resource in place then processing it at the surface without moving rock from the ground The method used depends on the type of mineral resource that is mined its loion at or beneath the surface and whether the resource is worth Insitu mining which is primarily used in mining uranium involves dissolving the mineral resource in place then processing it at the surface without moving rock from the ground The method used depends on the type of mineral resource that is mined its loion at or beneath the surface and whether the resource is worth
