Coal is a solid combustible mineral formed gradually from ancient plants that were buried underground and underwent complex biochemical and physicochemical changes. It is a solid combustible organic rock, mainly from plant remains by biochemical action, buried and then transformed by geological action, commonly known as coal.
Coal has a wide range of uses, and can be used for power generation: about 1/3 of China's coal is used for power generation, and the average coal consumption for power generation is about 370g/(kW-h) of standard coal. Power plants use the calorific value of coal to convert heat energy into electricity; steam locomotives use coal. Coal for building materials: about 13% or more of the coal used for power, with the largest amount of coal used for cement, followed by glass, bricks, tiles, etc.; metallurgical coal used for power is mainly anthracite used for sintering and blast furnace blowing, and its usage is less than 1% of the amount of coal used for power.
Coal Investment Prospects
China is a large coal producer and a major exporter in the world coal market. in 2003, the global coal production was 390 million tonnes, and China's coal production amounted to 178 million tonnes, accounting for about 46% of the total global production. In terms of export, China exported 14.75 million tonnes of coking coal in 2003, of which 4.58 million tonnes were exported to the European Union (EU), accounting for about one-third of the total. 14.72 million tonnes of coal were exported from China in 2004, equivalent to 56% of the total amount of coal traded globally, with the supply of coal still exceeding the demand in the international coal market. 2008 saw China's coke production totaling 327 million tonnes, and the output of coke from January to September 2009 was 252,768,700 tonnes. In 2008, China's coke production totalled about 327 million tonnes, and from January to September 2009, coke production was 252,768,700 tonnes.
Coal beneficiation process
Coal is generally processed by beneficiation methods. In the beneficiation process, it is necessary to go through pre-election, re-election, flotation, combined re-election and flotation process and combined metallurgical process. The equipment needed are flotation machine, spiral classifier, stirring tank, spiral chute and other equipment. If the coal material is too big, then it needs to be crushed before beneficiation.
