Naik et al. [13] investigated three reagents for coal flotation including sodium meta-silicate, collector (Kerosene) and frother (MIBC) on recovery of the operation. They concluded that the sodium meta-silicate has positive effect on recovery whereas the Kerosene …

US5443158A Coal flotation process Google Patents

A process for the flotation of particles of lignitic coal, subbituminous coal or oxidized bituminous coal contained within a slurry of coal and gangue, comprising the steps of dispersing a surfactant throughout the slurry, first conditioning the slurry such that the surfaces of the particles of coal are selectively coated by the surfactant to produce activated particles of coal, dispersing an ...

The Flotation System Optimization in Alborz Sharghi Coal

This paper tries to determine an optimum condition for the flotation operation of the Alborz-Sharghi coal washing plant. For this purpose, a series of comprehensive experiments have been conducted on representative samples from feed of the flotation system of the plant. Four operational variables such as the collector dosage (Fuel oil), the frother dosages (MIBC), the pulp density percent and ...

The effect of particle size on coal flotation kinetics A

Coal flotation is a very complex process that is characterized by a large variation in physical and chemical properties of treated material, i.e. coal and mineral matter. It is the most efficient separation method for coal particles within a narrow size range, normally from 50 m to 600 m (Trahar and ...

Ash Depression in Fine Coal Flotation Using a Novel

The current study investigated the effects of novel hybrid polyacrylamide polymers as ash (slime) depressants in fine coal flotation to enhance combustible recovery and ash rejection. Coal samples at P80 of approximately 45 um with ~25% ash content were floated in the presence of in-house synthesized hybrid aluminum hydroxide polyacrylamide polymers (Al(OH)3-PAM, or Al-PAM).

JAN D MILLER Research Faculty Profile The University

Contributions to the technology of coal preparation include flotation chemistry for improved rejection of pyrite and ash, procedures for the selective flotation of fossil resin from coal, and most recently the use of X-ray computed tomography both for high speed coal washability analysis.

Froth flotation 2

Jun 23, 2013 Venkatesh Naik. 1 year ago ThetNaingTun8. 2 years ago Sheshu Babu ... themajority of the gangue reaching the froth is from the finerparticle size fractions.o As the rate of coal flotation increases, the rate of gangueflotation increases proportionately. This is typical of a frothentrainment process acting on the gangue.

PDF Determining optimal conditions for lignite flotation

In this study conditions for flotation of low rank coal (lignite of Tuncbilek, Turkey) were investigated in detail. The experiments were performed using the 3-variable 2-level (2 3 ) full factorial experimental design with four base point replicates, and the results were analyzed by the regression model, Fischer test (F-test) and Halbich's upgrading curve for the responses of ash content (or ...

Optimization of coal flotation using statistical technique

Naik et al. (2004) performed a 2 5 factorial design on low rank coal flotation to study the effect of diesel oil, Methyl isobutyl Carbinol (MIBC), particle size, p H and sodium silicate. They also...

PDF Prediction of operational parameters effect on coal

Naik et al. [23] assessed the effect of three most important reagents for coal flotation: sodium silicate, collector (kerosene) and frother (MIBC), using 2 3 full factorial designs.

COAL FLOTATION Mineral Processing amp Metallurgy

May 23, 2017 Flotation is carried out at low solids, usually under 10% dilution. In the U. S. on bituminous coal the trend is toward open type No. 30 “Sub-A” Cells, single overflow, and with supercharging. Flows of dilute pulp up to 1500 GPM are effectively treated with excellent results through a single 4-cell machine.

Fine coal flotation in a centrifugal field with an air

Coal flotation circuits for tlIch separations are becoming more important in the processing 411=:-690/AID : (-28 mesh) coal (Miller, Podgursky, and Aikman, Aplan. 1979; and Burger. 1980). For example in the US in ,81 flotation plants processed 24 kt/d (26.500 tpd); whereas ~980, there were 80 flotation plants which processed 71 kt/d
