2004-2-4  Surface Chemistry of Phosphatic SlimesIn the beneficiation of Florida phosphoric claywaste by selective flocculation to recover francolitefrom clay minerals (montmorillonite), the surfacechemistry of phosphate as well as associatedmin.erals was found to play an important role. Poly-acrylic acid (PAA) was used as a flocculant forfrancolite since there is specific interactionsbetween the carboxylate group on PAA and thecalcium sites on francolite. While high separationefficiency could be obtained with artificial mix-tures of francolite and monnnorillonite using poly-acrylic acid as a flocculant, the efficiency fornatural phosphate

Mining and Beneficiation Phosphate Research Network

There are two types of flotation processes which are used in phosphate ore beneficiation: direct and reverse flotation. We talk about direct flotation when phosphate minerals are floated and reverse flotation when they are mineral impurities which are floated. Some processes are combination of both direct and reverse flotation.

The beneficiation of ultrafine phosphate ScienceDirect

2012-2-1  1. Introduction. Phosphate beneficiation operations around the world which use flotation as the principal mechanism to concentrate the phosphate bearing minerals, typically discard the “ultrafine” phosphate bearing particles, where for this study “ultrafine” is defined as particles being smaller than 20 μm.It is standard practice in the phosphate industry to separate the ultrafines by

Review on Beneficiation Techniques and Reagents Used

Phosphate ore is an important raw material for manufacturing fertilizers and phosphorous chemical products. While most of the phosphate resources cannot be directly treated as feed stock due to the low grade of P2O5 and high content of impurities. In order to obtain a qualified phosphate concentrate, the beneficiation of the low-grade phosphate ore is, hence, of great necessity.

Beneficiation of phosphate ores by electrostatic processes has been demonstrated by various researchers since the 1940’s. Separations have been achieved by removing silica from phosphates, and with fewer examples of calcite and dolomite from phosphate. Limitations on conventional electrostatic systems include low capacity, the need for multiple stages, and operational problems caused by fines.
