Enhanced Recovery by Hydrotropes in Oxidized Coal Flotation
Abstract: AbstractSo far flotation proved its best in improving the concentration of low grade fines by recovering the maximum with the use of advanced flotation reagents. In this context we propose the process optimization with the use of hydrotropes as activators in the coal flotation process. It is observed that sodium benzoate a known hydrotrope helped in increasing the recovery of the concentrate percent from 12.8% at plant condition to 31% …

Design and Fabrication of Pedal Operated Air Compressor
Abstract: The first idea for powering the pump would be a stationary bicycle. Pedal power is simple, efficient, and practical. Its most familiar use is the bicycle for personal or cargo transportation. But pedals can also power small stationary machines. Since the system is to remain human powered and large amounts of power are required, having the operator use their stronger leg muscles was intuitive. A stationary pedal driven device seemed …
