Combined microflotation effects in polymetallic ores beneficiation
Polymetallic ores are the most difficult to enrich [1, 2].Non-ferrous metal ores are very diverse and changeable in terms of chemical and mineral composition, nature of dissemination and textural and structural features, oxidation degree, hardness, crusability, grindability, enrichability [3,4,5].The peculiarities of the material composition of The significant applications of iron ore flotation are reviewed along with an abbreviated discussion on theory and reagent use. Problems or conditions which have militated against a widespread adoption of the flotation process by the iron ore industry, are discussed in contextual relationship to supply, economics, alternatives, and process Iron ore flotation: Practice, problems, and prospects

Flotation Improvements at Lac Des Iles Concentrator SGS
ore mineraloGY Host rock mineralogy is dominated by silicates (Figure 1). Feldspars, amphiboles and chlorite constitute more than 75% of the ore. Pyroxene, a major constituent of the South African PGM ores, is relatively uncommon at Lac des Iles. Much of it is altered to talc. The talc content in the Lac des Iles ore varies between 2 and 4 percent.The ore is crushed, screened, and then fed to the concentrator, where it is subjected to grinding (rod and ball mills), classification in hydrocyclones, low intensity magnetic separation, desliming in hydrocyclones, flotation and dewatering etc. Figure 4 Typical phosphate processing flowsheet Traditionally, the desliming stage is designed toiron ore concentrator 3rd scavenger flotation
