< 250 words) Although skarn ores are one of the largest metal resources in Europe, its processing is often challenging due to a very fine grained and intergrown mineralization. Other challenges have to be overcome if the valuable minerals are tungsten bearing minerals (i.e. scheelite or wolframite) due to their brittleness which requires to carefully design the beneficiation flowsheet in order ...

International reference materials representing a diverse suite of sulfide ores and related lithologies have been analyzed for major and trace element concentrations by XRF, solution ICP–MS, and laser-ablation ICP–MS (LA–ICP–MS) after fusion of the sample to a lithium borate glass. Reference materials analyzed for this study include a wide variety of bulk compositions, including ores of Pb–Zn su...

Nickel (Ni) is an economically important metal characterized by its mechanical strength and anticorrosion properties. With the increasing industrial demand for Ni depleting accessible primary ores, sustainable technologies are required recovery of this from alternative resources. In study, adsorption using chitosan was investigated as a technique to recover sulfate (SO42−) calcium (Ca) rich sec...

Soils in the Lower Swansea Valley, (United Kingdom) contain elevated level of metals, enough to cause direct or indirect effects on human health. This study assesses severity soil pollution and bioavailability Cu other metals (Ni, Zn, Co, Pb Cr) soils with various distances from a Ni refinery. We compare concentrations operationally defined fractions (bioavailable, bound Fe/Mn oxide incorporate...

Mineral ores are full of metals, some very precious – but how to extract them? The Hamersley mines in the Pilbara in Western Australia contain such rich iron ore that it can almost be welded as it comes out of the ground. Traditionally, metals are extracted by ‘smelting’ or pyrometallurgy, the thermal treatment of minerals and metallurgical ores and concentrates to bring about physical and chem...
