Cu-Ni-Co matte obtained by pyritic smelting of copper converter slag was leached at elevated pressures. The leaching studies were carried out using a factorial design for optimisation. Regression equations for the extraction ...

Reduction of iron ore fines by coal fines in a bed fluidized by air has been studied, The investigation includes study of the kinetic aspect of reduction and effect of major process variables. The variables used are time, ...

The MnO/NaCl/MgO catalyst shows high activity, C-2 selectivity and C-2 space time yield (STY). Catalyst samples have been prepared using different polymorphic forms, viz., alpha-, beta-, gamma-, and delta-forms of manganese ...

A procedure has been developed for the analysis of iron green pigments based on their reaction with an alkali. The composition of the blue component of the green pigment has been ascertained. The analysis involves determination ...
