The demand for rare earth elements for everyday technology and applications has initiated much research into the extraction and recovery of these rare earth elements. An otherwise unknown group of minerals, eudialyte is a zircon silicate consisting of rare earth oxides (REO), contained in a unique mineral structure and represented by a …
A laboratory scale prototype RTS unit has been used to investigate the effects of major process parameters on particle charging efficiency and phosphate separation efficiency for Florida phosphate samples. Experimental results have shown that the RTS technology upgraded a 10% P2O5 feed (16-35 mesh) to a 30% P2O5 concentrate with a …
About (400–450) m 3 /h of wastewater is discarded by Eshydia Phosphate Mine/south of Jordan. These effluents consist of 14% solids assaying 18% P 2 O 5; which means that 9600 m 3 of fresh water and 200 tons of valuable P 2 O 5 are discarded daily. Therefore, recycling of these effluents will have a significant economical and …

Aggregate production is estimated to be 48 billion ton in 2015 with an estimated annual growth rate …
The recovery of these vital elements from phosphate wastes may help to develop the needs of the green energy of the future and contribute to the achievement of …
This paper comprehensively reviews the phosphate beneficiation techniques, reagents and the factors affecting phosphate flotation, aiming at providing a guideline for the development and utilization of phosphate ores in the future.
In addition, flotation tests and X-ray fluorescence show that the required quality of phosphate concentrate was obtained at 31.05% P 2 O 5 with a recovery of 98.21% at pH 5.
Heavy metal contamination of clay waste through the phosphate beneficiation process is a serious problem faced by scientists and regulators worldwide. Through the beneficiation process, heavy metals naturally present in the phosphate rocks became concentrated in the clay waste. This study evaluated the concentration of …
