Coal Cleaning US EPA

Fine coal processing and coarse coal processing use similar operations and equipment to separate the contaminants. The primary difference is the severity of operating parameters. The majority of coal cleaning processes use upward currents or pulses of a fluid such as water to fluidize a bed of crushed coal and impurities.

Managing water consumption in mining Mining Technology

Aug 21, 2013· In 2005 the mine used more than 3,500 megalitres of water from the lake to run operations. By 2009 they had reduced this to 300 megalitres – a 95% drop. Rio Tinto did this by capturing and recycling water used by the processing plant, the biggest user of water, and capturing seepage from tailings, which also get recycled.
