As beneficiation of coal fines containing enriched vitrinite is essential to maintain the quality of metallurgical coke, due attention needs to be paid to revamp/renovate the fine coal circuits. At least 60% recovery of clean coal at 18%
ROM coal quality such as increased percentages of dirt, coal fines and moisture, which eventually add to the problems of coal beneficiation. The fine coal circuits in coal washeries are intricate, needing close attention and careful
Coal plants worldwide are reaping the benefits of our Sub325® fine coal recovery system – stockpiling more clean coal to their coal belts at moistures between 15 and 23% with no capital cost! Previously, minus 325 mesh (44µm ...

While disposing of fine coal without use was cheaper and more permissible previously, recovering some of the fine coal changes the mass balance of wastes and makes co-disposal or integrated dumps possible. The present study aims to investigate the processing of fine lignite coal tailings with 59.08% ash content from Soma tailings …
Several studies on column flotation have focused on the froth stability and the pulp level, entrainment of fine particles, flotation rate, product grade/recovery relationships and carrying capacity. Goodall and O'conner observed that decreasing air rate and increasing frother concentration reduce entrainment and produce stable froth together with small bubbles in lab-scale column flotation.
