Beneficiation of phosphate ores by dry electrostatic processes has been attempted by various researchers since the 1940's. The underlying reasons for developing dry processes for phosphate recovery are the limited amount of water in some arid regions, the flotation chemical costs, and the wastewater treatment costs.

2. Biotechnology for recovery of rare earth elements from solution. It is well known that microbial cells have a strong affinity for REEs [4-9].As well as by simple biosorption bacterial systems can accumulate metals as heavy bio-mineral deposits, e.g. see Macaskie et al. [].Metallic ions (e.g. UO 2 2+, La 3+) can be converted into metal phosphate minerals (HUO 2 PO 4, LaPO 4) enzymatically.

Rare earth elements (REEs) are critical and strategic materials in the defense, energy, electronics, and automotive industries. The reclamation of REEs from coal combustion fly ash has been proposed as a way to supplement REE mining. However, the typical REE contents in coal fly ash, particularly in the United States, have not been comprehensively documented or compared among the major types ...

The maximum flotation of sphalerite was observed with phosphate buffer (pH 8.0). Fig. 1 shows a representative trend obtained with an anionic buffer (phosphate) and a cationic buffer (tris-HCl). The intriguing and antagonistic role of the anionic and cationic buffers is presumably related to the nature of the bioreagent (see Discussion).
