2020521&ensp·&enspDeep sea mining is a mineral retrieval process that takes place on the ocean floor.Ocean mining sites are usually around large areas of polymetallic nodules or active and extinct hydrothermal vents at 1,400 to 3,700 metres (4,600 to 12,100 ft) below the oceans surface. The vents create globular or massive sulfide deposits, which contain valuable metals such as silver, gold, copper

2020516&ensp·&enspHeavy mineral sands are a class of ore deposit which is an important source of zirconium, titanium, thorium, tungsten, rareearth elements, the industrial minerals diamond, sapphire, garnet, and occasionally precious metals or gemstones.. Heavy mineral sands are placer deposits formed most usually in beach environments by concentration due to the specific gravity of the mineral grains.
2 &ensp·&enspMineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.The primary operations are comminution and concentration, but there are other important operations
