In the early 1900s electrostatic separation became popular in mineral processing until the advent of froth flotation However in more recent times the move towards environmentallyfriendly processing techniques ie reducing the use of chemicals and with many mineral processing plants facing water supply issues there is an increased3931
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 providing4092
In froth flotation process the pH value of the pulp needs to be paid close attention to at all times The pH value needs to be measured with a test paper every once in a while to ensure that the pH value remains at a stable value And the pulp concentration and liquid level need to be stable ensure scraping foam to scrape out the full plate3340
Pyrite can use xanthate as the collector in acidic neutral and weak alkali slurries The acidtreated pyrite has good floatability the optimum pH for the use of xanthate is 45 For the flotation of pyrite the ability of xanthate to collect is better than that of dithiophosphate 2 Xanthate Application in Sphalerite Froth Flotation4334
1 Introduction Flotation is the most common concentration process used by the mineral industry both in quantity of ores processed and in diversity of applications Peres et al 2007At present over 2 x 10 9 t per year of ore is estimated to be processed through flotation In Brazil this technique played an important role in the growth of the mineral sector especially in the industry of3294
This invention relates generally to ore flotation processes and more particularly to mineral flotation agents for use in ore flotation processes 2 Description of the Prior Art Froth flotation is a commonly employed process for recovering and concentrating minerals from an ore or a concentrate of the ore4313
Froth flotation is the most widely used phosphate ore separation process Because of the nature of the phosphate ore such as mineral types and content disseminated particle size its separation difficulty and flotation types varies Phosphate ore is divided into siliceous phosphorite calcareous phosphorite and siliceous phosphorite according to the chemical composition of the mineralsThe4081

Jul 23 2014018332Froth flotation is a method for separating hydrophobic materials which will not mix with water from hydrophilic materials which readily mix with water Since its discovery froth flotation has been a major component for the processing of sulfiderich3577
and flotation was carried out for 3 min scraping off the froth every 5 s The pulp level in the microflotation test was kept constant by adding a background solution prepared at the same chemical4019
Flotation is known as one of the methods which can separate minerals on the basis of differences in the mineral surface properties In the flotation process mineral particles with hydrophobic surfaces attach to air bubbles generated at the bottom of a flotation column and float up to form a froth3927
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilicThis is used in several processing industries Historically this was first used in the mining industry where it was one of the great enabling technologies of the 20th century3779
Dec 20 2018018332The 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 cost4689
Silvia Serranti Giuseppe Bonifazi in Use of Recycled Plastics in Ecoefficient Concrete 2019 244 Flotation Flotation processes are based on the different surface wettability properties of materials Wang et al 2015In principle flotation works very similarly to a sink and float process where the density characteristics of the materials with respect to that of the medium where they3054
Froth flotation separation of minerals differing little in density but greatly in wettability by surfactants that stabilize a froth formed on the surface of an agitated suspension of the minerals in water See4454
A separation process is provided for treating a feed material comprising silica feldspar and metal impurities including at least one of mica iron impurities or refractory heavy minerals to form one or more products for use in making glass In the process the feed material is floated in the presence of a depressant to inhibit the flotation of feldspar and thereby form a concentrate3455
Nov 18 2020018332Electrostatic separation is a process that uses electrostatic charges to separate crushed particles of material An industrial process used to separate large amounts of material particles electrostatic separating is most often used in the process of sorting mineral ore This process can help remove valuable material from ore or it can help4681
A collector composition for use in concentrating metallic mineral ores by froth flotation which comprises a mixture of a mercaptan and an emulsifying or wetting agent adapted to improve the dispersion of the mercaptan into the pulp and a froth flotation method for concentrating metallic mineral ores wherein the above collector composition is employed as the collector are disclosed herein3886
