INTRODUCTION
This leads to serious limitations for optimization of these processes and also their use for beneficiating ores of different origin and composition. Recently, Moudgil and Chanchani [7,8] and Ince [9] have conducted some fundamental studies which resulted in the development of two processes for the removal of dolomite from apatite.

Method of beneficiating phosphate ores containing dolomite
A method of beneficiating a phosphate ore containing silica and an alkaline earth metal carbonate impurity, particularly dolomite or calcite. The steps include testing the ore for excessive levels of carbonate impurities, the use of conventional flotation steps to remove silica, grinding the ore to a particle size in which at least 90% of the ore particles are less than 0.355 mm and thereafter ...

Dry beneficiation of iron ore
The haematite ore in South Africa is processed in a dry process to a HQ lump ore with 64 % iron content and a sintered fine ore with 63.5 % iron content. For fine ore beneficiation, wet processes are used. Capacity at the Minas Rio is to be increased from 26.5 Mta capacity to 28 Mta in the forthcoming years. Ore is beneficiated in a wet process.
