Purification of phosphate beneficiation wastewater: Separation of phosphate from Eshydia Mine (Jordan) by column-DAF flotation process
سنة النشر: 2012
ملخص البحث المنشور:
About (400–450) m3/h of wastewater is discarded by Eshydia Phosphate Mine/south of Jordan. These effluents consist of 14% solids assaying 18% P2O5; which means that 9600m3 of fresh water and 200tons of valuable P2O5 are discarded daily. Therefore, recycling of these effluents will have a significant economical and environmental impact on Jordanian phosphate industry. In this contribution we used a combined column and Dissolved Air Flotation (DAF) to recover phosphate particles. Flotation experiments were conducted in bench scale column and DAF flotation cells. Commercial fatty acid (DSR) was used as phosphate collector while Methyl Isobutyl Carbinol (MIBC) and sodium silicate were used as frother, and depressor, respectively. Maximum phosphate recovery obtained by column flotation was (20%) with 20% P2O5 at the following flotation parameters: 1kg/t collector dosage, 8L/min air flow rate
