Research on flotation in inorganic salt solutions to extract humus from coal in the Mao Khe region

Abstract

To find the advanced strategy and technology in boosting the quality of coal in humus form in the Mao Khe region, a wide range of experiments were undertaken to determine the ideal modes. First, coal humus samples were processed utilising froth flotation in distinct sorts of liquidity, including tap water and sodium chloride, without a set of collector reagents in divergent levels. As a result, the humus with an initial ash content of 61.85% was subjected to froth flotation in a 0.1M NaCl solution, which is half of the normal concentration, yielding a coal product with an ash content of 25.38%, a combustible material yield weight of 82.43%, and a waste component rate of 88.44%.
