Flotation Process and Reagents in Oxidic Iron Ores Koolnoch

Jun 19, 2022Flotation is a technique that is used in the processing of minerals by concentrating valuable material from ore. Flotation is a physiochemical separation process that utilizes the difference in surface properties of the valuable minerals and the unwanted gangue minerals. The method is adapted to a wider range of separation of various minerals.

Improved Flotation of Oolitic Hematite Ore Based on a Novel Cationic ...

However, a novel cationic collector for silicon removal, EM506 was found to be specifically selective to separate the gangue minerals from the iron ore with an increase of TFe grade from 49% to more than 58% and a recovery of TFe greater than 96%, which provided a promising approach for the beneficiation of the refractory oolitic hematite ore.

Copper Extraction Metallurgy: Mining, Concentration Smelting

Jun 13, 2022The iron is removed from the ore as an iron silicate slag. The sulfur present in the ore gets converted into Sulfur dioxide. The reaction can be written as follows: 2CuFeS 2 + 2SiO 2 + 4O 2 → Cu 2 S + 2FeSiO 3 + 3SO 2. After the extraction of copper, it is converted into Matte Copper after mixing it with the slag.

Optimization of Reverse Cationic Flotation of LowGrade Iron Oxide from ...

Current procedures are time and cost intensive. Batch laboratory scale reverse cationic flotation was employed to concentrate lowgrade Fe ore, found in fluorspar tails in the form of hematite. This study used two types of depressants (soluble starch and dextrin) and two types of amines (primary monoamine and tertiary monoamine).

Finding baseline flotation parameters for the reverse flotation ...

The fundamental mechanism for selective flotation of hematite is attributed to the selective depression of hematite, where quartz particles may be removed from hematite in a narrow pH range. In this pH range, amine collectors form an ionmolecular complex, which induces hydrophobicity on the surface of quartz particles and attain its frothing ...
