Flotationis widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complexoremixtures formerly of little value have become major sources of certain metals by means of theflotation process. This article was most recently revised and updated by Chelsey Parrott-Sheffer, Research Editor.

Theiron oreparticle size can largely affect the crushing and grinding stage, which is mainly to dissipate for usefulmineral oremonome and provide appropriate particle size for theiron ore flotation process.Iron ore flotation processis mainly to absorb theiron oreparticle size and deliver it to the slurry surface, then the scraper of
In this paper, several studies describing theprocessing of ironores via direct and reverse cationic and anionicflotationare reviewed. The objective of this review was to present and identify the effects of differentflotationconditions on removal of specific impurities iniron oresuch as quartz, alumina, phosphorous, andsulfur.
Compared with original sample, sulfur content decreased 95.06%, iron grade increased by 9.25%, and iron recovery was 94.13%. From the results it can be concluded that this microbial process for high sulfur iron ore lead to a significant effect of sulfur reduction and substantial increase in iron grade.
From the formula, it is clear thatironandsulfurhave to be removed in order to produce copper. The roastingprocess: changes some of the CuFeS 2 to copper oxide; removes some of thesulfurassulfurdioxide; This is done by heating the concentratedorefrom frothflotation. It is heated to between 500 °C and 700 °C in air.

RFC-Upscaling proposes the RefluxFlotationCell (RFC) technology formineral processingcompanies, with ROI in 3 – 4 years. Within the project, it is planned to commercialise the technology as a new product of FLSmidth for copper andiron ore. The RFC requires 30 % less capex and 20 % less opex compared to the existingflotationtechnologies.
