In this article a new spent catalyst sample preparation method was implemented for the purpose of molybdenum leaching in a single step. Further molybdenum and vanadium in the leach liquor were separated and their concentrations were enriched using th

We report on the effectiveness of a two-stage sequential integrated bioleaching process for enhanced recovery of metals from decoked spent petroleum catalyst. Fourier transform-infrared spectra confirmed that decoking led to removal of entrained hydr

The effect of sequential leaching such as bioleaching followed by bioleaching and bioleaching followed by chemical leaching is aimed at enhancing metal (Mo, Ni, V and Al) dissolution from a differently pretreated (acetone washed/decoked) spent cataly

The nitrogen solubility and nitride capacity of CaO-SiO2-Al2O3-MgO-CaF2 slag systems were measured by using gas-liquid equilibration at 1773K. The nitrogen solubility of this slag system decreased with increasing CO partial pressure, with the linear
