Mining

Mining

Mining is an activity of taking valuable minerals precipitate and economic value of the earth's crust, either mechanically or manually, on the surface of the earth, under the earth's surface and subsurface water. The result of these activities, among others, oil and gas, coal, iron ore, tin, nickel, bauxite, copper, gold, silver and manganese ore.


excavation

Excavation is an activity that involves taking all kinds of mineral products. Mineral products are chemical elements, minerals and all kinds of rock which is a natural sediment (not including metals, coal, oil and gas and radioactive materials). The excavated material is usually used as raw materials or auxiliary materials industry and the construction sector. The results of the excavation activities, among others, the mountain stone, stone, limestone, pebbles, marble stone, sand, silica sand, quartz sand, kaolin, clay and others.

Solving activities, smelting, refining and processing all mining / quarrying excluding mining / quarrying, but classified into industrial activities.

Mining excavation site preparation activities such as construction of roads, bridges and toward the location of mining, dredging, installation of transmission mains and so belong to the construction activities. While the activities of exploration and research on the prospects of the mining and mineral goods belong to the mining services.

Filming, cleaning and purification of water to be used as clean water, including in the water sector.


Stages of Mining Activities

Stages of mining activities include: prospecting and research, exploration, mining preparation and development, exploitation and processing / refining / purification.


Prospection

Prospecting is an activity of investigation and search to find precipitate minerals or precious minerals.

Exploration

Exploration is an activity that includes the continuation of prospecting works to determine the size, shape, position, grade average and the size of the reserve as well as the "feasibility" of sediment minerals or precious minerals have been found.

Exploitation

Exploitation is a mining activity that includes jobs uptake and transport of sediment minerals or precious minerals to the landfill and processing / washing, sometimes to the point of marketing.

Treatment / Purification / Refinery

Treatment / Purification is a work of purifying / elevate the levels of minerals by separating the valuable minerals and worthless, then discard the valuable minerals that are not (can be done by chemical means).
