The World's Long, Messy Breakup With Coal

Jan 27, 2021Coal-fired plants across the world are shutting their doors. In India, new coal construction has slowed dramatically: Over the first half of 2020, the country retired more coal capacity than it opened. In Europe, 19 EU countries and the U.K. have pledged to phase out coal by 2030.Spain may well become the first country in the world to completely close down its coal

Then, the coal is transported to a raw coal silo, usually 10,000 ton capacity, for feed to the plant at a constant rate. In this instance the first stage is a crushing/screening plant, with heavy media processing (for coarse coal sizes - 2 x 10 mesh), spirals for the middling sizes (10 mesh x 60 mesh), flotation for the -60 mesh fine coal feed.

How Coal Works

Preparation generally includes crushing the coal and removing heavy, extraneous non-coal materials. If coal is high in sulfur or other impurities, it is washed with a water or chemical bath, removing up to 40 percent of inorganic sulfur in the coal. Not all coal is prepared using the same process.

Dense Medium Separation

Dense medium separation (DMS) is a robust process that can be conducted at particle sizes as coarse as 300 mm and as fine as 500 m with high separation efficiency, depending on liberation characteristics of the value minerals. The DMS process involves three steps: feed preparation, dense medium separation, and ferrous-based media recovery.

Heavy Media Separation

The heavy media process is usually used for treatment of coarse coal above 9.5 mm in size. Finer coal below 9.5 mm cannot be cleaned economically in heavy medium. The settling velocities of the fine material are very low, and consequently the time required to separate the lighter coal from the heavy becomes excessive.
