Evaluation of some optimum moisture and binder conditions for coal .

At this moisture level the greatest compression strength gains were observed, and low amounts of fines produced in impact and abrasion tests. The minimum amount of binder added while still obtaining a strong briquette was 0.5% binder A. For binder B the optimum moisture level was also 12% and the minimum amount of.

Effect of froth stability on dewatering of coal flotation concentrates .

The results show that high froth stability originating from a flotation process has a negative impact on the filtration and dewatering of flotation concentrates. In this study, the flotation of fine coal using saline water produced a highly stable froth with a high air recovery resulting in a short cake formation time and a high final.
