Colombia is rich of minerals and energy resources. It has the largest coal reserves in Latin America, and is second to Brazil in hydroelectric potential. Colombia's coal output has increased consistently from 4 million tons in 1981 to 65.6 million tons in 2006, when it contributed 1.4 percent of the world's coal production.
Coal production plays important role in Colombia economy development. Colombia has more than seven billion tons of coal in measured reserves and with only 73 million tons being mined in 2009, there is significant opportunity for the development of the coal industry in Colombia. The major Colombian coal producers - Cerrejon, Drummond and Prodeco - are expected to see a doubling of their capacity in the coming years. This means coal will continue to play a significant role in Colombia's future economic growth. At present, more than 90% of Colombia's coal is exported and with coal demand remaining strong worldwide, especially with the continued economic expansion in China, coal will play a major role in Colombia's future export income.
Coal production line also known as coal beneficiation plant or coal washing plant. It refers to the processing operation of run-of-mine coal to improve coal quality and to enhance its suitability for final applications. The coal production line design depends on the properties of the coal and its final use. It may require only simple crushing operation or it may need to go through a complex production process to reduce impurities.
To remove impurities, the raw run-of-mine coal is crushed by crushing plant and then screened and separated into various size fractions. Larger material is usually processed by dense medium separation. In this process, the coal is separated from other impurities by being floated in a tank containing a liquid of specific gravity, usually a suspension of finely ground magnetite. As the coal is lighter, it floats and can be separated off, while heavier rock and other impurities sink and is removed as waste.

Coal can be mined by open pit and underground mining method according to deposit properties. When coal seams are near the surface, it may be economical to extract the coal using open cut mining methods. Open cast coal mining recovers a greater proportion of the coal deposit than underground methods, as more of the coal seams in the strata may be exploited.
Most coal seams are too deep underground for opencast mining and require underground mining, a method that currently accounts for about 60 percent of world coal production. In deep mining, the room and pillar or board and pillar method progresses along the seam, while pillars and timber are left standing to support the mine roof.
Zenith provides high quality coal mining equipment for sale. Mining equipment involved in coal mining plant includes drilling and blasting machine, quarry machine, extraction plant, mobile crushing plant, coal preparation equipment, coal sieving equipment etc. The selection of the processing flow sheet is probably the single most important step in the plant design process.
