bismuth flotation depressants
Flotation Optimisers and Depressants Borregaard
Our flotation depressants are proven to be effective on a variety of gangue minerals: Sulfide minerals, like pyrite, pyrrhotite, arsenic and bismuth sulfides Oxide minerals, like silicates, talc and calcite Clays and graphite Sulfate minerals, like baryte and gypsum Check availability and packaging The use of PA in the flotation resulted in the decrease of bismuth content in the molybdenum concentrates The observations suggest that PA detrimentally affects bismuthinite, which further suggests that PA can be used as a potential depressant to selectively separate molybdenite from bismuthinitePyrogallic acid: A novel depressant for bismuthinite in Pyrogallol, an ecofriendly derivative of tannic, was a potential substitute of toxic depressant used in bismuthmolybdenum (Bi–Mo) sulfide ore flotation However, unclear depression mechanisms of pyrogallol on bismuth sulfides hindered its further application in the industryDepression behavior and mechanism of pyrogallol on

Studies on a New Type of Organic Depressant for CuMo
A new organic depressant (termed as CM1) for the molybdenite and chalcopyrite flotation separation is studied The flotation results show that the depressing effect of CM1 on chalcopyrite is better than those of sodium sulfide and thioglycollic acid, and the amount Other auxiliary flotation agents which may be used are depressants, activators, precipitation agents, dispersing agents, organic colloidal materials and the like In the flotation process according to the present invention, the crushed ore or mineral (400 microns to 5 microns) is added to water so that the resulting slurry contains about 10 to PROCESS OF FLOTATION OF MINTERALS AND ORES Abstract Numerous inorganic and organic reagents are employed in flotation for the purpose of controlling the characteristics of interfaces Any species, whether organic or inorganic in nature, which has a tendency to concentrate at one of the five possible interfaces (such as liquid/gas, liquid/liquid, solid/liquid, solid/gas, solid/solid) is a surface active agentFlotation Surfactants SpringerLink
Process of froth flotation using a methylene
This patent describes a process of froth flotation for the recovery of a sulfide mineral, or a sulfidized oxide mineral, from an ore containing the sulfide mineral or sulfidized oxide mineral It comprises: subjecting the ore in the form of an aqueous pulp to froth flotation in the presence of a sufficient amount of methylene bisxanthate to act Slow flotation kinetics, leading to the target mineral being lost to coarser or finer size fractions; NeoSolutions is the industry leader in foam management capabilities for froth flotation applications Our surface modifiers are used to increase throughput, grade, Mineral Processing Neo Solutions, Inc Shamsipur, M, et al, Selective ion flotation separation and concentration of ultra trace amounts of bismuth using arsenazo III and its determination by inductively couple plasmaatomic emission spectrometry, Separation Science and Technology, Vol45, No9, 2010Minerals Engineering International Online Froth
