Regenerative therapies such as mesenchymal stromal cells (MSC) are appealing as they have inherent antimicrobial, anti-inflammatory, and immunomodulatory properties, which can be augmented by immune activation and play a role in resolution of

Reagents used in the flotation of phosphate ores: a critical review

01.07.2003In direct flotation, phosphate minerals are floated at basic pH with usually anionic collectors and depressant/modifier for gangue minerals. In reverse cationic flotation, siliceous gangue materials are floated from phosphate ore at around neutral pH using a cationic amine type collector. On the other hand, Conclusions 1.
