The need to develop green steelmaking techniques has led the replacement of reducing agents such as CO with H2. H2 and N2/H2 mixtures can be used for carbothermal reduction iron ore. In this study, we investigated swelling index ore pellets in a forming gas (N2/H2) atmosphere at temperatures 700–1000 °C compared it that pure experimental results showed increases increasing temperature both atmo...

There has been much work in exploiting the potential field relationships to extract information from the data. Kanasewich and Agarwal in 1970 explored the validity of examining the magnetization to density ratio in the wavenumber domain as an interpretation tool. Directly combining magnetic and gravity derived gravity gradient data in the spatial domain through the Poisson relation has been acc...

Th is study aims at studying effect of anaerobic dissimilatory iron (III) reducing bacterial consortium on different phases of iron present in lateritic n ickel 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 ...

The main purpose of geometallurgy is to develop a model to predict the variability in the mineral processing performance within the ore body. Geometallurgical tests used for developing such a model need to be fast, practical and inexpensive and include as an input data relevant and measureable geological parameters like elemental grades, mineral grades and grain size. Important in each geometal...
