Abstract: Magnetic seeding depression (MSD), i.e. adding organic depressant (such as starch) and magnetic seeds and applying a low field intensity pre-magnetization for depressing target mineral in flotation, was investigated in the reverse flotation of hematite ore slimes. Flotation tests found that the
Apr 01, 2014· Recovery of iron values from banded magnetite quartzite (BMQ) ore by direct and reverse flotation technique is presented. In direct flotation, with oleic acid as the collector, the iron grade in the concentrate that could be achieved is limited to 57% Fe from a feed containing ~ 47% Fe.The difficulty of concentrating iron values by direct flotation technique is due to the fine coating of iron ...
Mar 07, 2019· Magnetite (Fe3O4) is an iron ore mineral that is globally mined especially for steel production. It is denser (5.15 g/cm3) than Earth's crust (~2.7 g/cm3) and is expected to accumulate at the ...
Keywords ddakerosene magnetite ore quartz flotation introduction quartz is the most primary gangue mineral in an iron ore reverse flotation to remove quartz has been proved to be a very effective technique in the industry reverse cationic flotation of quartz uses mainly fatty amines .
N-acidylated amino acids, ether acids, modified carboxylic and phosphonic acids were proposed to enhance flotation selectivity of apatite from brazilite–apatite–magnetite ore [5–7]. The highest flotation selectivity of apatite was obtained with Flotol-7,9 collector, the main operating component of which are 1-oxyalkylidene-1,1 ...
The present invention relates to the art of freeing magnetite-bearing mineral particles from naturally associated silicious gangue mineral particles whereby to produce a concentrate low in silica, and is particularly concerned with the beneficiation of magnetite concentrates by flotation.
