Fluorinated hydrocarbons in coal mining and beneficiation . United States Patent 4178233 . Abstract A method of using fluorinated hydrocarbons as a carrier to convey mined coal to a separation station. The carrier acts as a parting liquid for beneficiating the coal. The carrier is recovered and returned to the mine for conveying more coal.
May 20, 2021 RAISING BENEFICIATION EFFICIENCIES IN COAL. 1 month ago. With South Africa now working hard to contain the cost of its coal-fired power generation, efficiencies are vital throughout the value chain not least in beneficiation. This means the continuous improvement in coal beneficiation technology and regular equipment upgrades in plants will become more important,
Coal Beneficiation Coal beneficiation is a process by which the quality of raw coal is improved by either reducing the extraneous matter that gets extracted along with the mined coal or reducing the associated ash or both. Two basic processes of beneficiation Dry-deshaling Non-coal or shaly-coal is removed without using any liquid media.

By maintaining an underground beneficiation focus we will reduce unnecessary haulage of waste material and reliance on port-based sorting. Initial knowledge developed has included an assessment of risk benefits in thin and low seam coal mining. We are also looking at mining
mining is used for deep seams. Underground mining methods vary according to the site con-ditions, but all involve the removal of seams fol-lowed by more or less controlled subsidence of the overlying strata. Raw coal may be sold as mined or may be pro-cessed in a beneficiationwashing plant to re-move noncombustible materials up to 45
