The present study investigates the optimization and advanced simulation of flotation process coarse particles (–425 + 106) using micro-nanobubbles (MNBs). For this purpose, experiments in presence absence MNBs were performed on quartz particles, results statistically analyzed. Methyl isobutyl carbinol (MIBC) was employed as a frother for generating through hydrodynamic cavitation. significance ...

Tabas mines in Iran have coal sources which are suitable for use in metallurgy industries as coking coal. But the high sulfur content of this coal imposes severe limitations on its utilization as the sulfur oxide gases evolved from the combustion of high sulfur coals result in acid rains and corrosion of equipments. In this work, attempts have been made to reduce sulfur from high sulfur coa...

Response surface methodology (RSM) is one of the most effective tools for optimizing processes, and it has been used in conjunction with Analysis Variance (ANOVA) test to establish effect input factors on output factors. However, when this mineral flotation, its polynomial model usually performs poorly. An alternative use artificial neural networks (ANNs) such situations. Within context, ANOVA ...

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)...

This paper is one of a study that implements reverse flotation methods as an alternative beneficiation on bauxite processing. aimed at decrease silica content and increase alumina in so its qualified feed Bayer Process. The experiments were carried out 1375 mL cell tank. Dodecylamine (DDA) AERO 3000C used the collector, starch depressant, Dowfroth 1012 frother. overall conducted solid to soluti...

The molecular structure of the liquid–vapor interfaces aqueous solutions alkali metal halides and methyl isobutyl carbinol (MIBC, (CH3)2CHCH2COCH3) is determined by using dynamics simulations with polarizable force fields for first time. salts are chlorides, iodides, some which found in raw partially desalinated seawater increasingly used flotation operations regions affected severe prolonged d...

Abstract Gilsonite has a wide variety of applications in the industry, including manufacture electrodes, paints and resins, as well production asphalt roof-waterproofing material. ash is determining parameter for its application some industries (e.g., gilsonite with content < 5% used an additive drilling fluids, resins). Due to shortage high grade (low ash) reserves, aim this study develop p...

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...
