Froth Flotation of Iron Ores

Froth Flotation of Iron Ores

Jan 02, 2012 With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a century’s practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore

Method of producing iron ore concentrates by froth flotation

We claim: 1. In a process for the removal of phosphorous from, and for the production of, iron ore concentrates by flotation, in which crushed crude iron ore is mixed with water and a collector to form a suspension, air is introduced into the suspension in the presence of a reagent system and a floated foam containing said phosphorous formed therein along with a flotation residue comprising an

the most popular flotation route in iron ore industry, the direct flotation of iron ox ides still appears desirable for some low grade iron ores that contain a vast amount of quartz. For example, at Republic Mine, Michigan, U.S.A., a hematite ore is upgraded from 36.5% Fe to 65.4% Fe with a Fe recovery of 82.5% using the direct flotation route

Dec 12, 2015 Iron ore flotation usually requires grinding of the ore to a particular size smaller than 149 m to achieve liberation. In general the following strategies can be used for iron ore flotation. 1. Reverse cationic flotation of quartz. 2. Direct flotation, in which iron oxide minerals (hematite) are floated using anionic collectors. 3

Desilication Application and Defoaming Mechanism of XK-28

Jun 21, 2021 The study explored a new combination amine collector (XK-28) that can obtain better flotation index and defoaming rate for magnetic iron ore. A pure quartz mineral test indicates that dodecylamine, XK-I, or XK-II has good collection effect on quartz and their best flotation pH is in the range of 6–7. The experimental results of a combination collector (XK-I:XK-II = 2:8.) show that the

May 01, 2018 As a collector for phosphate flotation, the length of the carbon chain and the number of the double and triple bond have a significant impact on the flotation efficiency. Collectors with a carbon chain below 16 or above 18 contain more contents of saturated fatty acid, a relatively lower content of double bonds, and contribute to a less effective flotation performance [20] , [21] , [22]
