Scheelite flotation

Schescheite CaWo4, containing 380.6% of Wo, was collected by fatty acid and its soap in flotation. Sodium carbonate is commonly used as pH regulator.When using fatty acid as collector, the optimum pH is 9~10.Inhibitors can be water glass, dextrin, starch and so on.Although scheelite is good in floatability, from the economic point of view, the recovery of coarse scheelite is usually by redoing

COARSE FLOTATION 911metallurgist

COARSE FLOTATION OFFERS IMPORTANT SAVINGS THROUGH REDUCED OPERATING COSTS Grinding cost varies greatly depending upon the size reduction required. For example, it takes approximately 50% less horsepower to grind from 189; to 48 mesh than it does to grind the same material from 189; to 100 mesh. Many minerals are liberated at a coarse mesh and middling particles often can

The highmolecularweight PObased frothers are more effective for coarse particle flotation than the alcohol or lowmolecularweight PO frothers, but also have a lower selectivity. For both good coarseparticle recovery and good selectivity, the PO frothers should be

Flotation taking its coarse

Coarse flotation is becoming more important as ore grades decline; when ore grades are lower, there is less ore suitable for beneficiation. As a result, new mines need to process additional tonnage to extract the same amount of metal or minerals as they would extract from highergrade deposits.

Coarse and Fine Particle Flotation Recovery

In The Days of gravity concentration, the art of ore dressing developed on the cardinal principle of saving the values at as coarse a size as possible. Flowsheets were designed which featured an alternation of crushing and concentrating operations. Thus an ore might be crushed to 189; inch, jigged to yield a finished concentrate and a middling; the latter being recrushed to 188; inch, jigged a

DESCRIPTION Coarse flotation followed by regrind of coarse rougher concentrate and selective flotation or cleaning. Coarse flotation tailings and reground rougher concentrate are processed over a shaking table for precious metals. ORE TREATED Ores wherein the minerals can be freed from the gangue at a coarse mesh and subsequently separated from each other after finer grinding.

Jameson cell

The high intensity of the Jameson Cell means that it is much shorter than conventional column flotation cells (see Figure 1), and it does not require air compressors to aerate the suspension of ground ore particles and water (known as a slurry or pulp) in the flotation cell. The lack of a requirement for compressed air and the lack of moving parts means that power consumption is less than for
