(PDF) Reagents in iron ores flotation ResearchGate

The main concentration method for iron ore enrichment is the reverse cationic flotation, in which the iron ore, typically hematite, is depressed (Filippov et al., 2010;Ma et al., 2011) using

The entrainment effect on the performance of iron ore

2016-10-1  The typical feed to a flotation system applied in the cationic reverse flotation of quartz from hematite in the iron ore industry consists of particles in the size range between 10 μm and 300 μm. The slimes fraction (<10 μm) are removed using hydrocyclones prior to flotation and the top size is limited to 5–10% greater than 150 μm.

The Desulfurization of Magnetite Ore by Flotation with a

2019-8-15  problem in iron ore smelting process. However, the magnetic separation of pyrrhotite from magnetite is problematic, due to their similar magnetic property and magnetic flocculation between pyrrhotite and magnetite [3]. Flotation has been commercially used as a method for removing pyrrhotite from magnetite for high sulfurous iron ores [4].

Interactive effect of minerals on complex ore flotation:

Iron ore flotation is a complicated procedure. The presence of fine or ultrafine particles adversely affects iron ore flotation, which is probably due to the heterocoagulation and covering of fines. This process leads to variation in mineral surfaces, resulting in a low separation efficiency.

Treatment and Recycling of the Process Water in Iron

The samples for flotation were taken from on-site samples of flotation, which were ground to 95% passing 0.045 mm, and contained 34.90% specularite and hematite, 8.70% magnetite, 0.20% limonite, 39.40% quartz, 11.40% chlorite and hornblende, and 4.90% calcite and dolomite.
