    New perspectives in iron ore flotation Use of collector

    A two-stage iron ore flotation process was developed. • Amidoamine proved an effective collector for silicate. • Selective flotation of quartz and hematite was achieved with no use of depressant. • Kaolinite requires higher dosages of amidoamine for flotation. • Steric hindrance and hydrogen bonding could influence selective flotation.

    Minerals Special Issue Iron Ore Flotation

    May 12, 2021 Iron ore flotation is a key technique to concentrate intermediate-low-grade ore, in order to reach the market requirements for higher-grade concentrates of iron. The presence of some impurities in addition to quartz in iron ore, aluminium silicates, and minerals containing phosphorus impair productivity in the steel industry and have an impact ...

    What is claimed: 1. In a froth flotation process for separating silica from iron ore, which comprises frothing said ore in an aqueous medium in the presence of a cationic silica collector selected from ether amines of the formula: R--O--CH 2--CH 2--CH 2--NH 2. wherein R--O-- is derived from a mixture of normal alcohols, consisting predominantly of C 8 and C 10 carbon number alcohols, the ...

    ironore beneficiation by flotation

    Iron ore mining often focuses on looking for hematite deposits known as red iron ore, and magnetite, as they have naturally weak magnetic fields that aid in their purification. Hematite, however, responds better to the flotation process in iron ore beneficiation than magnetite, so it is the preferred type of ore.

    The other is to reduce the sulfur content via the iron ore beneficiation process. As a sorting process, flotation plays a fundamental role in this. The objective of the test campaign described below was to reduce the sulfur content in an iron ore concentrate from 1.3 % to less than 0.4 %.

  • The Characteristics of Iron Ore Slimes and Their Influence

    The Characteristics of Iron Ore Slimes and Their Influence

    The flotation has been successfully applied to process the iron ore for the particle size (Ps) from 10 m up to 150 m. The presence of the slimes (Ps 10 m) is harmful on the reverse flotation of quartz, so they are usually prior removed by hydrocyclones. The main effects of the presence of slimes on the flotation are related to the increase on reagents consumption, the froth stability ...

    Jan 20, 2021 The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents: Frothers (MIBC) is what allows the formation of air bubbles.
