Flotation using cationic surfactants has been investigated as a rapid separation technique to dewater clinoptilolite ion exchange resins, for the decontamination of radioactive cesium ions (Cs+) from nuclear waste effluent. Initial kinetic and equilibrium adsorption studies cesium, suggested large surface area volume ratio fine zeolite contributed fast kinetics high capacities (qc = 158.3 mg/g)...
Froth flotation is an operation currently used for the recovery of Cu from pyrometallurgical smelting slags due its simple and relatively low operational costs. While it has been utilized many decades, may be necessary to develop strategies that improve slags, as unprecedented increase in demand made industrial waste side streams economically relevant sources metals. This study presents a novel...
In this research work, the effects of flotation parameters on coking coal flotation combustible material recovery (CMR) were studied by the artificial neural networks (ANNs) method. The input parameters of the network were the pulp solid weight content, pH, collector dosage, frother dosage, conditioning time, flotation retention time, feed ash content, and rotor rotation speed. In order to sele...
This study investigates removing ash and pyrite sulphur from bitumen by column flotation process. Central composite design (CCD) of response surface methodology (RSM) was applied for modeling and optimization of the percentage of ash and pyrite sulphur removal from bitumen. The effects of five parameters namely the amounts of collector and frother agents, particle size, wash water rate and feed...
this paper tries to determine an optimum condition for the flotation operation of the alborz-sharghi coal washing plant. for this purpose, a series of comprehensive experiments have been conducted on representative samples from feed of the flotation system of the plant. four operational variables such as the collector dosage (fuel oil), the frother dosages (mibc), the pulp density percent and t...
