phosphate apatite process and beneficiation

Mining and Beneficiation Phosphate Research Network

To concentrate phosphate rock in apatite (BPL or P2O5 content) we have to separate impurities from apatite using a beneficiation process. The beneficiation process could include a large variety of operations depending on the rock impurities content, the particles size and their hardness.

The present paper deals approach adopted in beneficiating the average grade apatite ore of Purulia. Key Words: apatite, Purulia, iron, magnetic separation, flotation Introduction Deposits of Phosphate in India is broadly categorised into phophorite and

2018-6-28  There are two types phosphate mining methods basedon the depth and deposit geometry, the surface (strip) mining method (for deposit up to 100m) and the underground mining method (for deposit greater than 100m). However surface mining such as strip mining can affect a wide area than underground mining does, therefore, can be an important factor of environmental degradation.18 Beneficiation is the process of removing the unnecessary minerals, which is used to increase the grade of mining product (concentrate). Phosphate ores can be beneficiated

Minerals Free Full-Text Review on Beneficiation

In order to obtain a qualified phosphate concentrate, the beneficiation of the low-grade phosphate ore is, hence, of great necessity. Many beneficiation techniques can be employed to upgrade the P 2 O 5 grade of phosphate ores based on their characteristics in chemical composition and texture.

Review on Beneficiation Techniques and Reagents Used

2019-4-25  The flotation process is most widely applied to balance the P 2O5 recovery ratio and cost. In this review, the dominant techniques for the beneficiation of phosphate ores are introduced. Moreover, the factors that affect the flotation of phosphate ore, including the properties of mineralogy, flotation reagents (depressants and

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 slimes was very low. This isattributed to the fact that polyacrylic acid interactsalso with montmorillonite when there are calciumspecieson its exchangeablesites. In the caseofnatural phosphate slimes, dissolved calcium spe-cies from francolite can adsorb on the exchange-able sites of the clay surfacesand activatepolyacrylic acid
