Feb 06, 2012This study aims at studying effect of anaerobic dissimilatory iron (III) reducing bacterial consortium on different phases of iron present in lateritic nickel ore. Such conversion in lateritic nickel ore are helpful in better recovery of sorbed metal values like Ni and Co by subsequent bioleaching or acid leaching. Here properties of thermally and microbially reduced lateritic nickel ore are

In its natural form, sodium sulfate is found in two minerals, mirabilite (Glauber's salt) and thenardite. Its occurrence is widespread and it i s commonly found in mineral waters such as sea water, atmospheric precipitation, and saline lakes. Essentially all commercial deposits of sodium sulfate resulted from the accumulation and evaporation of

Oct 31, 2008– Legumes are widely grown and are consumed as a source of plant protein throughout the world. They rank second after cereals with respect to their consumption order. Legumes have anti‐nutritional factors which make their uses limited. This study aims to check the effect of soaking and cooking on the anti‐nutrient contents and nutritional quality of the legumes., – Five legumes (white

May 10, 2018In saline water flotation, the salinity can cause a distinguishable slime coating of clay minerals on chalcopyrite particles through its effect on their electrical double layers in aqueous solutions. In this work, kaolinite was used as a representative clay mineral for studying slime coating during chalcopyrite flotation. The flotation of chalcopyrite in the presence and absence of kaolinite
