Abstract The nature and type of minerals associated with a lowrank (NCB 902) coal were determined by scanning electron microscopy and dispersive Xray analysis. The mineralogical examination showed the presence of fluorapatite and other minerals which would be troublesome on combustion. It also showed that the minerals would, to a large extent, be liberated by fine .
Although iron pyrites and other minerals are removed from coal on an industrial scale almost exclusively by gravity separation methods at the present time, other beneficiation methods are coming into use. Among the developing methods, froth flotation (1,2,3) is the foremost, although the oil agglomeration method (4,5,6) is also promising.

· Beneficiation of coal fines with high ash content was attempted in an operating coal preparation plant by retrofitting a m diameter pilot plant scale flotation column in the circuit. The collector and frother dosage were optimized as kg/t and kg/t respectively. At these reagent conditions the operating parameters of pilot scale flotation column were also .
The present study was carried out to beneficiate coal tailings sample using froth flotation technique. The aim of the investigation was to remove the carbonaceous material present and to reduce the environmental pollution generated through large volume of tailings from a coal preparation plant. The characterization studies show that the sample contains .
Apr 29, 2019 · This research investigated the beneficiation of lead in Wase lead ore deposit with the aid of gravity and froth flotation techniques with a view to determine the chemical composition and the mineral content of the crude lead ore; determine the liberation size of the valuable mineral; and to investigate the best technique to produce lead as charge into the blast furnace. .
VIIL1 Beneficiation Optimization and Clean Coal Production Conventional wet method beneficiation is relatively ineffective for treating fine coal. Hence a significant loss of energy occurs in the waste streams from coal preparation plants. Even when hydrocyclones are used to improve froth flotation performance maximum recovery is not possible since the ultrafines (75 .
· Froth flotation has been used to enrich sedimentary phosphate ores with siliceous impurities. It has replaced calcination in treating calcareous phosphate ores. It is also commonly used for processing igneous phosphate ores with usually less compliions compared to sedimentary ores.
Description : The process provides a process for the recovery of finest cleans from coal slurry which comprises conditioning slurry of fine coal particles of size below .5 mm by treating with frothers in a ratio of 1:10 and hydrocarbon reagents in a ratio of to under stirring for 8 hours, at a temperature of 25 to 30 °C passing the conditioned slurry through a plurality of .

The Mineral Beneficiation Group is engaged in R D in beneficiation of low grade ores and minerals. It has developed expertise and facilities towards carrying out studies on development of process flowsheets for beneficiation of low and lean grade ferrous, nonferrous, nonmetallic, industrial, refractory, strategic, fertilizer minerals, precious metals, coals and mine/industrial .
I claim: 1. In a method for the separation of iron pyrite from a pulverized mineral ore comprising iron pyrites as a first constituent and a second constitutent selected from the group consisting of coal and nonferrous metal ores by air froth flotation of an aqueous pulp of said pulverized mineral ore, the improvement which comprises incorporating in said pulp from about to .
I claim: 1. In a froth flotation process wherein solid coal particles are selectively separated under coal froth flotation conditions as the froth phase from remaining solid feed ash particles as an aqueous phase in the presence of a coal particle collector and a frother, the improvement characterized by the addition of an effective proportion of a hydrophobic, nonionic promoter .
