It is composed of sand, claw, water, and bitumen, which is an oil that is black and viscous. These sands can be mined, and then processed, to remove the bitumen. Once processed, then bitumen can be then refined into oil.
Open pit mining -- or strip mining -- is an extraction process for ore or fossil fuels that takes place at the surface of a mining site. Worldwide, 40 percent of mining occurs at the surface, according to Greenpeace International. Compared with underground mining, surface mining is much more efficient.
The dust and particles from mining roads, stockpiles, and lands disturbed by mining are a significant source of air pollution. This section describes the five main types of surface coal mining techniques: area mining, open pit mining, contour mining, auger miningand mountaintop removal. Underground mining is also considered in this section.
Tar sands are a fossil fuel resource. It is composed of sand, claw, water, and bitumen, which is an oil that is black and viscous. These sands can be mined, and then processed, to remove the bitumen. Once processed, then bitumen can be then refined into oil.
Sipho Kings 09 Nov During its projected 15 years of operation, it will excavate million tonnes of ore. It will spend R1.
Strip mining is a form of resource collection that involves dirt removal from a very large area to sift through it. Instead of working underground, a pit is created deep in the ground and all work is accomplished on the surface. Here are the pros and cons of strip mining to consider.
Learn something new every day More Info Strip mining is a form of surface mining that is usually employed for the recovery of materials such as coal and tar sand, which are relatively near the surface of the earth. Surface vegetation, soil, and rocks are removed in strips, often in conjunction with controlled explosions, to make removal more efficient.
Coal bed methane CBM can typically be found in coal beds that have not been strip-mined or that are too far underground for strip mining. In these areas, the beds act as reservoirs, holding and releasing methane based on the porosity of the coal. Even sites that have been deemed uneconomical for coal mining may contain usable CBM if the extraction is simpler, and less expensive, than that of coal mining. CBM is extracted from coal beds through the drilling of wells.
