froth flotation differential

CPC Definition B03D FLOTATION; DIFFERENTIAL

Differential sedimentation is used for separating a mixture of particulate material into its fractions (for a definition of differential sedimentation, refer to the glossary of terms). Differential sedimentation type separation apparatus or methods that may include coagulation or flocculation. Relationships with other classification places

Differential froth flotation Brinker, Frederic A.

A method for the differential froth flotation of an ore pulp containing antimony sulfide and gold bearing pyrites and arsenical pyrites comprising supplying to the pulp a soluble lead compound to produce an activating condition for floating the antimony sulfide and a non-activatIng condition as to the pyrites, adding a frothing agent and floating off the antimony sulfide from the pyrites by the froth flotation

FLOTATION; DIFFERENTIAL SEDIMENTATION (sedimentation in

Flotation Froth flotation (or simply flotation) is a physico-chemical separation process that utilises the effect that different materials normally show also differences in surface properties (e.g. surface tension), for separating a mixture of materials into its fractions. This difference in surface properties yields in a different tendency of

Froth flotation Wikipedia

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

Differential froth flotation Brinker, Frederic A.

A method for the differential froth flotation 70 separation of antimony sulfide and gold bearing pyrites contained in an ore, comprising preparing a pulp, froth floating the pyrites with the aid of excess caustic soda and a copper compound forming copper hydroxide to produce an activating 75 condition for floating the pyrites, and froth floating the antimony sulfide with the aid of a soluble

CPC Definition B03D FLOTATION; DIFFERENTIAL

Froth flotation involves thus three phases (solids, water, gas) with complex interactions and subprocesses. In a typical flotation process water and chemicals are added to a mixture of solids to form a pulp. The pulp is then copiously aerated and the preferred (aerophilic) species clings to bubbles and floats as a mineralized froth, which is then skimmed off.

Modelling for froth flotation control: A review

01/03/2021· Froth flotation is affected by several variables, such as the flowrates into the flotation cell, i.e. feed, air and froth wash water, The froth phase was modelled by using Partial Differential Equations (PDEs), considering the froth as a Plug Flow Reactor (PFR). The PFR assumption considers that the froth phase is not mixed in the flow direction, but is perfectly mixed in the direction

Differential froth flotation of sulfide ores Gibbs

Quite particularly, the process relates to froth flotation, and to the concentration of metalliferous sulphides such as those of molybdenum, copper, iron, zinc and lead. More specifically the invention relates to the use of certain agents novel in flotation practice, by means of which some of the mineral values are depressed, while other minerals or impurities are caused to float by any usual
