Influence of attrition variables on iron ore flotation

All flotation variables were kept constant and taking into account the three attrition variables under study, only the rotation of the impeller in the attrition cell influences the metallurgical recovery of the flotation. Attrition is a known step in the enrichment process of phosphate and silica sand. However, its effects on iron ore are an unknown process. For situations where there is reduced bibliographic information and

Influence of attrition variables on iron ore flotation -

Research has been undertaken for its application to produce pre-concentrates of zircon and iron ore. However, there is still little knowledge of the influence of the attrition variables on the beneficiation process of iron ore. This study presents a factorial design and analysis of the effects of these variables on the reverse flotation of iron ore.

Influence of sodium silicate modulus on iron ore

2013-12-10  This paper presents the influence of sodium silicate modulus on iron ore flotation with sodium oleate collector. Bench flotation tests were performed at pH 7 with actual iron ore from Quadrilátero Ferrífero, Brazil, with 42.8% Fe and 37.2% SiO 2. Iron recovery averaged above 90% and the Fe contents in the concentrate were above 55%.

Lead ions that originate from galena during the processing of complex sulfide ores migrate onto the surfaces of sphalerite and iron sulfide minerals. This results in poor selectivity during differential flotation. Generally, in sulfide ore processing, the lead-activated minerals float in the Cu/Ph rougher circuit. The surface lead complicates the zinc flotation circuit by lowering the ...
