a froth at the surface of the liquid and is skimmed off as a con centrate. The wetted mineral particles remain in the main body of the flotation slurry, or pulp, and are continuously or peri odically drained out as a tailing. The flotation mechanism is most efficiently carried out in machin~s designed for this purpose. Flotation machines,
The froth velocity measurement can be used to adjust the pulp levels of individual banks. For example if the concentrate grade is low the general action would be to lower the pulp levels. However, if a bank has a low froth velocity and is not pulling, the individual action
Copper sulphate had a significant effect on the maximum froth height obtained in static three-phase froth tests. Proposals to explain these observation are made. If the above-mentioned thing is taken into consideration, the role of $ce{CuSO4}$ is to provide $ce{Cu}^{2 }$ which will act as an activator in the manner explained above.
A method of selectively recovering an arsenopyrite, pyrrhotite or like mineral from a material containing such a mineral and pyrite which includes the steps of providing a slurry of the material, adding a dialkyl (C 3-8 )-dithiophosphate to the slurry, passing a gas through the slurry to cause the mineral to be carried to the surface of the slurry and report in a first float concentrate

Oct 25, 2014Abstract. The dosage of a collector is an important factor that determines the efficiency of a froth flotation process. The representative sample of the carbonatitic Palabora copper ore ground 45 % passing 75 m was froth-floated with sodium isobutyl xanthate (SIBX) collector at 60, 70, 80, 90 and 100 g/t dosages.
A froth flotation process comprising preparing an ore pulp containing copper sulfides and sulfides of the group zinc and iron sulfides, sup- 30 plying a cyanide compound and thiocarbanilid to the pulp, adding a soluble lead salt to the resultant pulp to reactivate inhibited copper sulfides, adding a frothing agent, and subjecting the pulp to a .
High efficiency copper ore froth flotation,copper ore froth flotation for sale BF series copper ore froth flotation is designed on the basis of principle of Wei Muke flotation machine. 4. The circulation of mineral slurry is reasonable, and copper ore froth flotation can avoid the disposition of coarse sand to the largest extent.

Froth is then carried into the froth launder via mass action. These separators are specifically designed to have both a small footprint and gravity-driven feed system that allows cells to be easily "stacked" in-series or placed ahead of existing conventional or column flotation cells.
In the concentration by froth flotation of copper sulfide minerals from a feed comprising copper and other heavy metal sulfides, the method of reducing the copper sulfide minerals content in the tailing, which comprises forming an aqueous pulp of the ore, subjecting the pulp to flotation in the presence of a promoter selected from the group consisting of the xanthate, dithiophosphoric acids and
Flotation isolates materials by taking advantage of the surface tension of liquids and the ability of minerals to attach to air bubbles in liquids.4 Another innovation of the flotation process is its ability to alter the pulp chemically (in the water bath or ore pulp itself) allowing for an efficient separation of nu
Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process.
By using the same example which helps to explain the establishment of the material balance, this paper explains in what way the operating plant material balance in froth flotation can be used for

A process and flotation agents are provided for flotation of lead-, uranium-, and rare earth-type minerals and ores in which an aqueous pulp of the mineral or ore is subjected to a froth flotation, characterized in that the flotation is performed in the presence of a tertiary amine flotation agent. The process is especially applicable in the flotation of sulphide and oxide ores and minerals.

An improvement in the froth flotation separation of metallic sulfide mineral ores, particularly those ores bearing copper and molybdenum, in which a mercaptan collector is used in an earlier primary flotation stage, the improvement comprising the addition of activated carbon to achieve deactivation of the mercaptan collector prior to the component mineral separation stage, thereby providing
39 02715547 Fax 39 027490571 [email protected] 1 Introduction. The FLOTATION PLANTS are used in the mining industry to separate valuable minerals from gangue. The ore is extracted from the mine, ground in a mill and mixed with water and chemical reagents forming the pulp.
Sponsored Listing At the same time, refine the bubble, and make the minerals conglutinate on the bubble, and then float on the surface of the ore pulp, to form the mineralized bubble. Flotation is a selective process and can be used to achieve specific separation from complex ores such as lead-zinc, copper-zinc, etc. Flotation machines are subject to coarse separation, swept separation, fine
Rutile is recovered from copper ore tailings by means of a froth flotation process comprising (a) flotation of sulfides and carbonates at a pH of about 9 to 10, using sodium isopropyl xanthate and sodium oleate as collectors, and detrine as rutile depressant, and (b) flotation of rutile from the resulting tailings at a pH of about 2 to 3, using hydrofluoric acid as a rutile selectivity
Sep 16, 2018The process choice of ore flotation is determined by the raw ore properties. Here is a brief discussion of it. Precedence flotation is according to the hydrophobicity difference of the ore, based on the order of the priority to the easy to select the ore. The flotation used in the copper ore with coarse particle size dip dyeing or the richer ore. Mixed flotation is also called all flotation process. In the
