The preparation, characterisation and catalytic activities of chromia pillared montmorillonites were investigated. The Na-exchanged montmorillonite shows higher uptake of chromium(III) acetato complex than that of acid ...

Systematic studies have been made to understand the oxidation behaviour and dissolution reaction mechanisms operative while pure copper, zinc and lead sulphide minerals and mixtures, and single concentrates/mixtures are ...

Generally mess transfer data I pressure drop data obtained in forced convection of the electrolyte are correlated as a function of flow rate and physical properties of electrolytes and geometric variables studied. However, ...

Studies have been conducted on rheology of nickel laterite suspension at different temperatures, concentrations, particle sizes and pH for both fines and tailings from a hydrocyclone discharge. Fine laterite slurries exhibit ...
