The present paper describes the effect of srubbing on the flotation selectivity of Woxna fine graphite concentrate and the upgrading process of the material.

Results show that scrubbing in an attrition machine (with screened sand of −2.9+0.425 mm as attrition media) is an effective way to improve the flotation selectivity, and the material can be upgraded to over 94% from the feed grade of 87–88% carbon by an upgrading process consisting of scrubbing and two-step cleaning flotation.

The present paper describes the effect of srubbing on the flotation selectivity of Woxna fine graphite concentrate and the upgrading process of the material.

It is clear trend that flotation performance declines on increasing collector dosage from low level to high level for all three blended frothing molecules.The depression in selectivity is due to coverage of ash particle's surface by collector at higher dosage which results in a decrease in the flotation rate differentials between the low and high ash content particles in the feed coal.

Egypt, application of column flotation for recovery of Application of carrier flotation technique for fine particles (‐ 45 μ m), Table 7, indicated that the upgrading of Egyptian kaolin preconcentrate,using optimum conditions are : superficial gas velocity 0.84 83.33 kg/t of limestone with grain size of ‐25 + 10 μm,cm/sec., frother

The ash content of the concentrate of the mechanical flotation was 10.77% at the yield of 79.34%. In contrast, the yield of the concentrate of the column flotation was increased to 88.93% with 10.55% ash content. Comparative study of the Fuerstenau upgrading curves indicated that the column flotation

the so-called Fuerstenau upgrading curve, which relates the recovery of combustible matter recovery and recovery of ash forming minerals, both in concentrate. The Fuerstenau upgrading plot showed that the best selectivity was obtained for the middle size fraction of 0.25–0.075 mm, while the flotation selectivity of

Generally, the particle size of the bubbles is 0.02-0.06 mm. When used for the flotation of fine cassiterite, electrolytic hydrogen bubble flotation is used alone, and the recovery rate is Compared with conventional flotation, it is significantly improved, from 35.5% to

forming materials floated into a froth product at the start of flotation. Based on the Fuerstenau upgrading curves, it was determined that the 0.25-0.074 mm size fraction range showed the worst selectivity when compared with 0.50-0.25 mm and -0.074 mm size fractions. The desired concentrate with an ash content

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century. It has been described as "the single most important operation used for the recovery and upgrading of sulfide ores". The development of froth flotation

The potential for improved selectivity has made column flotation cells a popular choice for upgrading fine coal. Unfortunately, recent production data from full-scale column plants indicate that many industrial installations have failed to meet original expectations in terms of clean coal recovery.
