which ores are concentrated by froth flotation process?one example of the way in which an ore can be purified is the froth flotation method used with ores of copper, zinc, and some other metals. as these are normally low grade ores with fine grain froth flotation of aljustrel sulphide complex oreflotation objective was imperative for a good liberation grade and reagents dosage selection, mainly for complex sulphide ores. a useful contribute was given to a better technical understanding of flotation of a complex sulphide ore from the moinho deposit. keywords: froth flotation, mineral liberation, flotation reagents, complex sulphide ore the application of xanthate in froth flotation process2. xanthate application in sphalerite froth flotation. the sphalerite which surface is clean have low floatability. if the low-grade xanthate is directly used for its flotation, the recovery rate is low, so it is necessary to use high-grade xanthate to process the sphalerite. flotation of sulphide oresflotation process, patented in the year 1906, was origin-ally developed for mineral industry to recover values from high grade tailings of gravity seperation plants. this technology has acclaimed importance as a versatile process for the beneficiation of vast variety of sulphide mine-rals. comparative study of the effect of frothers on the flotation however, the performance of froth separation is affected by the types of frothers. the purpose of this study, therefore, was to determine the effect of different frothers in the flotation of low-grade nickel sulphide obtained in south africa. sodium isobutyl xanthate was used as a collector in this investigation. froth flotationgrade-recovery curves are useful tools in weighing the trade-off of producing a high grade of concentrate while maintaining as low of a recovery rate as possible, two important aspects of froth flotation. these curves are developed empirically based on the individual froth flotation process of a particular plant. flotation process for low grade nickel orefrom a low-grade (~0.3% ni) nickel sulfide ore as an alternative row material for metallurgical uses. processing nickel sulfide minerals by flotation always presents the challenge of obtaining appropriate selectivity between nickel sulfide and other sulfides, such as pyrrhotite, pyrite, and chalcopyrite. sulphide flotationclosed- and open-circuit flotation cleaning is used on gold mines where high-grade concentrates are required for roasting and smelting. under these conditions, it is difficult to maintain very high gold and sulfide flotation recoveries, while also producing an acceptable grade of concentrate. (pdf) flotation of an oxidized copper sulfide orepdf this paper presents the results of the characterization and processing of the hofrat en nahas copper sulfide ore from sudan (southwest of darfur). mineralogical examinations indicated that how to extract precious metals from sulfides sciencingextract sulfide ore deposits from the ground and place in to the crusher to mince ore from 5 to 50 micrometers. crushing begins the separation process by preparing the ore to be floated in water. first, the ore is crushed using a gyratory crusher to reduce the ore to 6-inch diameter pieces.

Advantages of froth flotation process is for low grade sulphide ore or high grade
