In flotation process, the efficiency and selectivity depend on mineralogy, particle size distribution liberation, reagents added, mixing, coverage. However, kinetics of recovery is highly dependent cell hydrodynamic circuit configuration operational strategy. Controlling froth depth gas flow rate, measured as superficial velocity, a straightforward alternative related to in collection zones. th...

Conventional hydrocarbon oil cannot adhere effectively to oxidized coal, resulting in a low yield of clean coal. In this study, high-speed homogenizer was used emulsify LDD (laurylamine dipropylene diamine) and kerosene, which enhanced the flotation efficiency The results showed an increase from 4.12% (only kerosene) 23.33% (emulsified oil). An contact angle indicated that mixture reagent can h...

Flotation is a common mineral processing method used to upgrade copper sulfide ores; in this method, particles are concentrated froth, and associated gangue minerals separated as tailings. However, significant amount of lost into tailings during the processing; therefore, can be considered secondary resources or future deposits copper. Particle–bubble collision efficiency particle–bubble aggreg...
