Froth flotation method has been an important part of the concentration process since the 1920s and today, more than half of the world's marketable phosphate is produced by froth flotation.
Finally, some remarks are made in respect to the key flotation challenges facing the iron ore industry and the areas that will need to be the focus of ongoing flotation research and development to maintain viability and relevance of the flotation process to the industry in the face of future ores that will be lower in grade, more complex in ...
Froth flotation is a process for selectively separating of 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.
The authors of the paper undertook to describe the ore flotation process with variable flotation properties. This is a difficult task because the flotation process, at the same time, is influenced by many factors of a different nature. In this manuscrypt, the introduction needs to be redrafted. The information presented in paper are too general.

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. This article was most recently revised and updated by Chelsey Parrott-Sheffer, Research Editor.
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 Flotation of Samples with Sulfurization of Oxidized Copper Ore For the sulfurization process, two samples were prepared in two different autoclave mediums: Sample A containing 18.37g H2S +120.00 g H2O for one kg of copper ore, and Sample B containing 24.50 g H2S + 160.00 g H2O for one kg of ore.
This copper–molybdenum (Cu–Mo) sulfide ore is generally mined from various locations in the mining site; thus, the mineral composition, oxidation degree, mineral particle size, and grade vary. Therefore, in the mining operation, it is common to blend the ores mined from various spots and then process them using flotation.
Remember that only 0.67% of the ore is copper. The copper minerals and waste rock are separated at the mill using froth flotation. The copper ore slurry from the grinding mills is mixed with milk of lime (simply water and ground-up limestone) to give a basic pH, pine oil (yes, it comes from trees -- a by-product of paper mills) to make bubbles ...
Flotation was discovered early in the 20th century, and today it is the most commonly used separation technology in the mining industry. Flotation separates valuable minerals (copper, lead, zinc, iron, and phosphate too) from the contaminating minerals in the ore (sand in this case).

an improved silica flotation collector for reverse flotation of calcite as their ore and needs were changing. The reason for the request was that the quality of the ore feeding the flotation plant had been reduced – resulting in lower recoveries – and that the current collector generated excessive froth in the flotation circuit as well as
A broad application of this process in industrial field is the flotation of iron ores which is of two types: direct and reverse flotation. The later one is again based on two different types as ...
Potash Flotation Process. Potash occurs in soft deposits generally associated with sodium chloride and varying amounts of clay slime, which because of its colloidal character, complicates the beneficiation process. Potash ores generally contain 20 to 40 percent KCL with the balance being NaCl and a small amount of clay slime, the latter usually ...
For more than a century now, flotation has been at the heart of the mineral processing industry. In this month's SPOTLIGHT FEATURE ARTICLE, direct from the November issue of INTERNATIONAL MINING magazine, John Chadwick examines new technologies and applications from some of the key players in mineral flotation, a technique that is so important to the global industry.
In this study, chitosan polymer was tested as a potential selective green depressant of pyrite in the bulk flotation of galena (PbS) and chalcopyrite (CuFeS 2 ) from sphalerite (ZnS) and pyrite (FeS 2 ) using sodium isopropyl xanthate as a collector and 4-methyl-2-pentanol (MIBC) as a frother. Flotation tests were carried out in a D12-Denver flotation laboratory cell in the presence and ...
The FLOTATION PROCESS is one of the commonest methods of extracting the valuable minerals from certain classes of ores, and it is generally more efficient as regards the recovery of the minerals than any other process applicable to the treatment of similar types of ores. The metallic contents of the minerals are recovered from the concentrates in a subsequent series of metallurgical …
