What is coal slag? This stuff is boiler slag, which is a recycled product from coal burning plants. When coal is "fired" at over 2500 degrees it melts and produces a byproduct called slag. When the slag is cooled through a process called vitrification, it crystallizes, forming .
FLY ASH Coal Combustion residue Fly ash is the finely divided mineral residue resulting from the combustion of ground or powdered coal in electric generating plant (ASTM C 618). Fly ash consists of inorganic matter present in the coal that has been fused during coal combustion. This material is
These minerals can be fairly easily removed by surface mining techniques. Other minerals occur in long streaks known as veins or in pipes, and underground mining techniques are used to access these minerals. Surface mining includes open pit mines, quarrying, strip mining and landfill mining. Coal and copper are often mined in this way.
Coal is a nonrenewable fossil fuel that is combusted and used to generate electricity. Mining techniques and combustion are both dangerous to miners and hazardous to the environment; however, coal accounts for about half of the electricity generation in the United States.
Lignite: Lignite coal, aka brown coal, is the lowest grade coal with the least concentration of carbon. Also, there is peat. Peat is not actually coal, but rather the precursor to coal. Peat is a soft organic material consisting of partly decayed plant and, in some cases, deposited mineral matter.
The Mining Process. Once access has been gained into the coal seam, workings are developed by mining a series of roadways (or " headings "). These roadways are tunnels largely, if not totally, within the seam, usually rectangular in shape though on occasions they may have an arched or even circular profile.

Initial public offering The first sale of shares to the public, usually by subscription from a group of investment dealers.
Coal production leads the Indian mining industry, accounting for 78 percent of total mineral sector production. India's coal reserve is estimated at billion tons (10 percent of global reserves). India's demand for coal continues to increase to meet the needs .
Anthracite coal is a dense, hard rock with a jet black color metallic luster. Lignite coal, or brown coal, is a very soft coal that contains up to 70% water by weight. Carbon forms more than 50% by weight more than 70% by volume of coal (this includes inherent moisture).
The aim of process calculations is to evaluate the performance of minerals and coal processing operations in terms of efficiency of the operation, grade of the final products and recovery of the required constituents. To meet these requirements, indepth.

Coal seams can be mined by surface or underground methods (Figure ), with the choice of mining method dictated by both technical and economic factors. The most important technical factors are the thickness of the coal seam, the depth of the coal seam, the .
Room and pillar method. One of the methods used in underground mining is called room and pillar, and is often used for mining coal. Part of the mine is open to the surface and part of it is underground. The coal face is dug out, but pillars of coal are left behind to keep the tunnels open and support the roof.
