BBC NEWS | Science/Nature | Clean coal technology: How it works

Coal washing involves grinding the coal into smaller pieces and passing it through a process called gravity separation. One technique involves feeding the coal into barrels containing a fluid that has a density which causes the coal to float, while unwanted material sinks and is removed from the fuel mix. ...

What is clean coal technology? | HowStuffWorks

When coal burns, it releases carbon dioxide and other emissions in flue gas, the billowing clouds you see pouring out of smokestacks. Some clean coal technologies purify the coal before it burns. One type of coal preparation, coal washing, removes unwanted minerals by mixing crushed coal with a liquid and allowing the impurities to separate and ...

Coal preparation plant Wikipedia

The coal delivered from the mine that reports to the coal preparation plant is called runofmine, or ROM, coal. This is the raw material for the CPP, and consists of coal, rocks, middlings, minerals and contamination. Contamination is usually introduced by the mining process and may include machine parts, used consumables and parts of ground ...
