The selective coating of colloidal magnetite on hematite and bauxite for enhancing the magnetic separation techniques which depends on surface and chemical phenomena is studied. The mechanism of colloidal magnetite interaction ...

Physico-chemical parameters such as salinity, pH, DO, BOD, chlorophyll-a, nutrients (NO2-N, NO3-N, NO3-N, NH4N, PO4-P, total phosphorus) and major ions (Ca2+, Mg2+, F-) were studied during February-March, 1994 in the coastal ...

The amenability of a calcite-bearing ore to the reduction of silica to below 0.2% by physical beneficiation was studied. The objective was to use the are as a raw material for seawater magnesia production. The ore contains ...

Fractorial design methods have been applied for optimizing the roasting condition to convert vanadium present in the vanadiferous titano magnetite ores to sodium vanadate. The different factors such as time, temperature ...

Dissolution of sphalerite and manganese dioxide minerals in the presence of one another in sulphuric acid medium was studied using compact disc electrodes of the minerals under various H2SO4 concentrations (0.01-0.5M) and ...
