Response of process parameters for processing of iron ore

2015-7-10  The processing of iron ore slime by mechanical flotation has been extensively studied but it was less understood with the column flotation. So in order to achieve the grade and recovery of iron values from slimes of Indian iron ore, rich in alumina and silicate minerals, the effects of process parameters need to be explored.

Column Flotation • Theory and Practice

2011-12-1  Column flotation which employs a counter-current flow of slurry and air bubbles has proved to be a better alternative to the conventional mechanical cells for separation of minerals. Because of the distinct advantages of column flotation over mechanical cells, it is gaining wider acceptance in industry. Realizing the potential of column flotation, RRL Bhubaneswar also took initiative in the early sixties to develop column flotation technology for Indian ores. In the early stages, operation and design of columns were mainly based on experience. But with the increasing commercial installations, systematic investigations have been carried out by several workers. In this paper an attempt is made to review the development of column flotation for concentration of low grade ores. The basic principles and applications of column flotation

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 µm up to 150 µm. The presence of the slimes (Ps < 10 µm) 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
