Dense media separation (DMS) is a gravity separation method in which a suspension material such as magnetite or ferrosilicon is used to form a medium denser than water in separation. This method is used to separate valuable materials from waste. Multotec supplies a complete range of DMS processing equipment, which includes a customisable and industry-proven range of …
Based on the obtained results by the investigation of the features of magnetite–hematite ores from the Mikhailovskoye deposit, a technological scheme of magneto-flotation beneficiation was...
Hematite represents the vast majority of iron ore exported from Australia as the development and processing cost of magnetite is generally seen as a barrier to the development of vast magnetite resources. However, a number of magnetite projects have attracted a significant amount of interest and investment from large Chinese steelmakers.This paper compares the …
The results of a theoretical option study for high capacity processing of a hard, fine-grained silica-rich magnetite ore is presented in this paper, with the emphasis on comminution circuit...
Historically, hematite was the preferred iron ore due to its direct usability in blast furnaces (BF) for steel production, without beneficiation (value improvement) costs. But with declining hematite ore quality and a shift towards low-carbon technologies such as DRI, the demand for high-quality magnetite ore is at historically high levels.
