Separation characteristics of different size and density fractions in batch coal flotation
M Vanangamudi C Vinod Kumar T C Rao
Batch flotation experiments were carried out using two coal samples to study the behaviour of each size and the density fractions in coal flotation. Different size fractions obtained from sizing of concentrates and tailing were subjected to float and sink analysis using organic liquids. The distribution curve technique was adopted to evaluate the performance of flotation. The results show that selectivity of flotation decreases with decrease in particle size. The specific gravity of separation is influenced more by the level of the frother dosage than by the collector dosage. The specific gravity of separation increases with increase in flotation time. The maximum value attained at infinite flotation time increases with decrease in particle size but the rate at which it is reached decreases.

Effect of some operating variables on the performance of a 76 mm heavy medium cyclone
M Vanangamudi J P Barnwal T C Rao
Tests were carried out on a 76 mm heavy medium cyclone-treating coal. The results show that the specific gravity of separation of coal is influenced not only by the specific gravity of the feed medium but also by the magnetite to coal ratio in the feed slurry.
