The single most important method used for the recovery and upgrading of sulfide ores, thats how G. J. Jameson described the froth flotation process in 1992. And its true this process, used in several processing industries, is able to selectively separate hydrophobic from hydrophilic materials, by taking advantage of the different categories of hydrophobicity that are increased byGet Price
Xanthate, as the flotation collector with strong collection effect, is mainly used to enhance the hydrophobicity of the mineral surface to meet the requirements of is commonly used in the flotation process of sulfide minerals. Xanthate is a combination of alcohol, sodium hydroxide and carbon dioxide, which is an anionic collector. . It is light yellow, soluble in water and
Copper is extracted in large amounts from the Earth39s crust by mining of sulphide ores and also oxide ores. The procedure of copper processing involves mining and transporting. Oxide ores are generally processed through hydrometallurgy heap leaching, solvent extraction and electrowinning. The sulfide ores are usually processed using the method of pyrometallurgy froth floatation, thickening
M.G. Aylmore, in Gold Ore Processing Second Edition, 2016. 5.1.1 Platsol Process. The Platsol process was originally developed in collaboration with the University of British Columbia, Kane Consultants Ltd., and Lakefield Research in Canada for the treatment of flotation sulfide concentrate for Polymet Mining Company in Minnesota and was tested on similar types of concentrate materials.
The process used to treat sulfide copper ores begins at the mine site, where the copperbearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining

Froth flotation is a process for selectively separating hydrophobic materials from is used in mineral processing, paper recycling and wastewater treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
Continuing with the evaluation of copper oxide flotation using hydroxamate we now evaluate a rock thats 41 copper oxide with some lead oxide included. Sample B 1.8 Copper about 41 Oxide Cu Rougher Tests Unseen in these charts is the order in which the results were obtained. The lastbest Blue dot the best data point was the last test of the series.

Sulfide ores. Secondary sulfides those formed by supergene secondary enrichment are resistant to sulfuric ores are a mixture of copper carbonate, sulfate, phosphate, and oxide minerals and secondary sulfide minerals, dominantly chalcocite but other minerals such as digenite can be important in some deposits.. Supergene ores rich in sulfides may be concentrated using
The froth flotation technique was originally developed in about 1910 to raise the copper concentrations of the stripmined ores of Bingham Canyon, near Salt Lake City 9, and was further perfected for the differential separation of lead, zinc, and iron sulfides at Trail, B.C., at about the same time 10. Flotation technologies are now widely
This data on chemicals, and mixtures of chemicals, commonly known as reagents, is presented for the purpose of acquainting those interested in froth flotation with some of the more common reagents and their various uses.. Flotation as a concentration process has been extensively used for a number of years. However, little is known of it as an exact science, although, various investigators have
Flotation Reagents amp Collectors. Froth flotation is the most widely used industrial process for the separation of finely liberated minerals. The process involves the aeration of minerals in water in the presence of flotation reagents which facilitate the attachment of air bubbles to and levitation of select minerals.
changes some of the CuFeS 2 to copper oxide removes some of the sulfur as sulfur dioxide This is done by heating the concentrated ore from froth flotation. It is heated to between 500 C and 700 C in air. The product from the roaster is called calcine. It is a solid mixture of oxides, sulfides and sulfates. One reaction that takes place is
Houston, TX, November 16, 2017 Clariant, a world leader in specialty chemicals to the mining industry, participated in the 8th International Flotation Conference Flotation 3917. The conference took place from November 13 to 16 at the Vineyard Hotel, Cape Town, South Africa.
Froth Flotation Process. The use of these reagents has been extended in recent years to three stage selective flotation. For example, ores containing the sulphide minerals of lead, zinc, and iron, can be treated to yield three successive concentrates, wherein each class of minerals is recovered separately more or less uncontaminated by the others.
Copper Sulfide Flotation Circuit. The pulp from the Conditioner is treated in a 10cell SubA Flotation Machine and a 4cell SubA Flotation machine. Sometimes conditioners are not provided however, their use insures that reagents are thoroughly mixed into the pulp ahead of flotation.
Frothers amp Froth Flotation. The importance of frothers in mineral flotation is widely acknowledged in the mining industry. Frothers perform the following key functions in the froth flotation process Reduce surface tension of the liquidgas interface to enable froth formation Hinder coalescence in order to stabilize bubble size
A method of extracting targeted metallic minerals from ores that contain sulfide metallic minerals along with oxide minerals, carbonate minerals, silicate minerals, halide minerals or combinations thereof. In the method, an ore slurry containing the metallic mineral in oxide, carbonate, silicate or halide form is provided. The slurry is activated by adding sodium thiosulfate and sodium
The froth flotation method is widely used to treat various veins of gold and silver ores for the following reasons 1 In most cases, the froth flotation process can enrich gold and silver in sulfide concentrate to the greatest extent and discard a large number of tailings, thus reducing the smelting cost.
Reverse flotation of carbonate minerals from refractory goldbearing sulfide ores requires the flotation of the carbonate minerals calcite, dolomite, siderite, etc. while depressing sulfide minerals and native gold. The flotation of carbonates can be achieved by anionic oxyhydryl collectors and this has been well established.
