Name of Commodity:    RUSSIAN GAS OIL

Name of Commodity: SANDS

Ship by barge to Singapore where it has been turned into square kilometres of new Singapore territory which becomes the location of new skyscrapers, hotels, convention centres and casinos.

Singapore Reclaim Lands

Singapore only imported about 517 million tons over 20 years out of 40 billion per year but this is a major part of imports because big countries can get sand from elsewhere in their own country

MINING

Surface mining operations, known as open-pit, open cast or open cut mines, are as their names suggest, open to the earth’s surface. Underground mines, in contrast, involve exploiting deep-lying ore bodies that are reached from the surface by incline or vertical shafts. Whether a mine is a surface or underground operation depends on a variety of safety, environmental, economic, geological and geotechnical factors. In general, surface mines present more advantageous opportunities to use the large scale mechanization that makes production safer, more efficient and more economical. However, many deposits are too small, irregular or deeply buried to be reached by surface methods and must be mined via underground methods. Transportation represents a large proportion of mining activity. In surface mines this is mostly transport of the mined ore and waste, while men and materials must also be transported to their working sites in underground mines.
Processing
Once mined ore has been recovered from the earth, we process it to remove as much waste material – gangue – as possible. This begins with the use of huge crushers and mills to reduce the size of the ore to liberate the valuable minerals so that they can be recovered and concentrated. Depending on the minerals present in the ore, concentration processes such as gravity separation, flotation or chemical leaching may be employed. Each technique uses the physical or chemical properties of the minerals to exploit the difference between valuable material and gangue. Coal, for example, is lighter than most rock particles, while conversely, diamonds are much heavier, and gravity processes that can exploit these differences in density are generally employed. Lead and zinc often occur together in orebodies, but can be separated by froth flotation processes that exploit the different chemical properties of the respective minerals.
