Application of statistical design in the leaching study of low-grade manganese ore using aqueous sulfur dioxide

Naik, P.K.; Sukla, L.B.; Das, S.C. (Separation Science And Technology, 37(6), 2002: 1375-1389)

Sulfur dioxide leaching studies on low-grade manganese ore were carried out at room temperature and atmospheric pressure. The experiments carried out using -150 mum particles aimed at determining maximum extraction of ...
Aqueous SO2 leaching studies on Nishikhal manganese ore through factorial experiment

Naik, P.K.; Sukla, L.B.; Das, S.C. (Hydrometallurgy, 54(2-3), 2000: 217-228)

Aqueous SO2 leaching studies of Nishikhal manganese ore containing 32.5% Mn and 16.5% Fe were carried out at atmospheric pressure and room temperature using H2SO3. The variables considered were SO2 concentration, solid-to-liquid ...
Effect of sodium metasilicate on natural flotability of coal

Naik, P.K.; Reddy, P.S.R. (Colloid And Polymer Science, 284(9), 2006: 1024-1030)

The effect of the quantity of sodium metasilicate and conditioning time in one set of experiments, and the effect of the solution concentration of sodium metasilicate, added at the same dosage and conditioning time to coal ...
Electrokinetics, adsorption and floatation studies of sphalerite using di (2-ethyl hexyl) phosphoric acid

Das, B.; Naik, P.K. (Canadian Metallurgical Quarterly, 43(3), 2004: 355-362)

Electrokinetics, adsorption and flotation studies have been carried out to investigate the possible interaction of the solvent extractant, di (2-ethyl hexyl) phosphoric acid (D(2)EHPA), with sphalerite. The zeta potential ...
Extraction of manganese from low-grade Nishikhal ore using pyritiferous lignite in acidic medium

Naik, P.K.; Das, S.C.; Sukla, L.B. (Minerals & Metallurgical Processing, 19(2), 2002: 110-112)

Leaching studies of low-grade manganese ore containing 31.77% Mn and 23.71% Fe from Nishikhal, India, were carried out using pyritiferous lignite as a reductant in sulfuric acid medium. The variables studied were quantity ...
Interpretation of interaction effects and optimization of reagent dosages for fine coal flotation

Naik, P.K.; Reddy, P.S.R.; Misra, V.N. (International Journal Of Mineral Processing, 75(1-2), 2005: 83-90)

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 ...
Leaching of low grade Joda manganese ore with sulphur dioxide in aqueous medium

Naik, P.K.; Nathsarma, K.C.; Das, S.C.; Misra, V.N. (Transactions Of The Institution Of Mining And Metallurgy Section C-Mineral Processing And Extractive Metallurgy, 112(2), 2003: C131-C134)

The feasibility of recovering manganese by leaching low grade ore with aqueous sulphur dioxide has been investigated. Successful extraction ivas achieved at atmospheric pressure and room temperature. The concentration of ...
