6/3 mm coal slime reduction of thermal coal processing was proposed. • A multi-parameter control method is put forward for the separation in shallow tank. • The yield of clear coal was 83.72%, and the value of E was 0.055 g/cm 3. • First thermal coal 3 mm flip

need for potable water. Our coal business, for example, is increasingly using lower quality water in its processing operations. Recycling and process water initiatives are vital to water security at our operations. Currently, 66% of water required is met by recycled water. Indirect use, which refers to all water use that takes place within the value chain and outside of our direct control, of

• Use of water spray systems and /or polymer coatings to reduce the formation of fugitive dust from coal storage (e.g. on sto ckpiles) as feasible depending on the coal quality requirements; • Capture of coal dust emissions from crushing / sizing activities and conveying to a baghouse filter or other particulate control equipment ; • Use of centrifugal (cyclone) collectors followed by

Oxidation

The term oxidation-reduction reaction actually refers to two chemical reactions that always occur at the same time: oxidation and reduction. Oxidation-reduction reactions are also referred to more simply as redox reactions. Oxidation, reduction, and redox reactions can all be defined in two ways. The simpler definitions refer to reactions involving some form of oxygen. As an example, pure iron

For coal, natural gas and nuclear, the water demand of the fuel cycle may be small when compared to cooling, but still represents a significant water use. Fuel cycle refers to the complete fuel production chain which consists of the following main stages: (1) extraction, processing and transport of primary fuels; (2) refining or other conversion processes; and (3) transmission and distribution
