Application of bioleaching of metals in a large-scale operation is reviewed briefly. Continued technical innovation is vital for the wider utilisation of this extraction process within the mineral industries. Therefore, ...

The photodegradation of phenol was studied in the aqueous solutions over titania pillared zirconium phosphate and titanium phosphate under solar radiation and compared with that of the UV-radiation (6 W low pressure Hg ...

The effect of three most important reagents for coal flotation namely sodium meta silicate, collector (kerosene) and frother (MIBC) was studied using 23 full factorial design. The regression models were developed using ...

Vapour liquid equilibrium (VLE) data are important for designing and modeling of process equipments. Since it is not always possible to carry out experiments at all possible temperatures and pressures, generally thermodynamic ...

Spent hydro-refining catalysts mainly consists of 20-22% MoO3, 5-6% NiO, 4-5% S, 1-2% CO3O4, 1.3-1.5% Fe2O3, 3-4% SiO2, and the balance is Al2O3. In the present study, one such spent catalyst was roasted with sodium chloride ...
