Coal preparation plant Wikipedia

A coal preparation plant is a facility that washes coal of soil and rock, crushes it into graded sized chunks (sorting), stockpiles grades preparing it for transport to market, and more often than not, also loads coal into rail cars, barges, or ships. The more of this waste material that can be removed from coal, the lower its total ash 

Washed Coal from a Utilization Perspective Rod Hatt pulse

The maintenance folk preferred coal that had low abrasion properties. The environmental people liked low sulfur and low ash levels. Then, the ash sales department wanted high ash to dilute the carbon and increase the sales volume. The fuel purchasing group liked low cost coals. Near the end of the discussion I asked if

The volume of waste from processing coal can be substantial 35 – 40 percent of the raw coal going into a typical washing plants was left behind as waste 

Sampling the coal chain

This can lead to a major problem later, when hopes of washing to produce a highergrade product would necessitate redrilling the reserve. This can be particularly galling, as drilling is usually more expensive than the analysis. Coal is low in density, thus a greater volume of sample needs to be taken than for other minerals.

The water challenge facing China's coal and power sector is

Jul 8, 2013 Coal is washed to improve its quality before being burned for power. The washing process reduces the levels of ash and sulphur, improving the energy content. It also reduces the weight of coal that needs to be transported and requires less desulphurisation by the power industry – a process which uses

small amount of sulfate remains w i t h the coal after a simple washing procedure. Preliminary results show that this can be reduced to starting values using more rigorous washing procedures. If we assure that all the sulfate can be removed, then the values for sulfur removal by ferric sul fate extraction can be raised 3 to 9%
