The principal separation in iron ore beneficiation, therefore, is between the iron minerals, hematite and/or magnetite, and silica, principally in the form of quartz. The use of flotation, either alone or in combination with magnetic separation, has been well established as an efficient method for rejecting silica from these iron ores.
Direct shipping of high grade iron ore, because of depletion or partial depletion of reserves, or high costs of operation has forced operators to use some means of beneficiation to produce an acceptable product with the lower grade iron ore reserves. Deposits of comparatively lower grade iron ore that remain relatively untouched or by-passed, are now most important because of increase in
In general, the industrial flowsheets for the beneficiation of itabirite iron ores from the Quadrilátero Ferrífero (Minas Gerais state) in Brazil involves grinding, desliming, magnetic separation and cationic reverse flotation using both mechanical and columns flotation cells. At Brazilian plants, it is estimated that Fe losses generated at the slimes stage range between 8% reaching values
Reverse flotation process: Hematite mineral reverse flotation process is a hematite beneficiation process of using anionic or cationic collectors to float gangue minerals from raw ore. In terms of the ore properties of hematite ore, reverse flotation process is more advantageous than the positive flotation
grade iron ore to produce quality raw material would play a key role in future which is a fact acknowledged by the iron and steel industry. [1,2] India is bestowed with rich iron ore reserves in the form of hematite and magnetite. Most of the iron ore mines produce hematite ores and have washing plants to produce lumps as well as fines.

Currently beneficiation of hematite ores is conducted using either direct flotation (hematite flotation) or indirect flotation (quartz flotation) tech-niques depending upon the nature of the available ore bodies. In direct flota-tion, iron bearing mineral, mostly hematite, is floated using oleate as collec-
Case1 —— Shanxi iron ore magnetic production line. This hematite iron minerals are mainly composed of magnetite, hematite with uneven distribution, and gangue minerals are quartz. After comprehensive analysis of ore properties Xinhai designed the stages grinding, gravity magnetic reverse flotation process--- about 60% coarse concentrate
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.
Currently the mining industry faces the challenge of rebellious iron ore processing. Flotation is one of the most used and efficient methods to treat oxidized ferruginous quartzite when it comes to low-grade iron ore (less than 40%) and it can produce high grade concentrates. Specialists of SP ZAO IVS has developed and patented a hematite ore
