Bog iron ores are widespread in Polish wetland soils used as meadows or pastures. They are suspected to contain high concentrations of heavy metals, which are precipitated together with Fe along a redox gradient. Therefore, soils with bog iron ore might be important sources for a heavy metal transfer from meadow plants into the food chain. However, this transfer depends on the different binding...

Abstract Mantle plume rich in gold is considered to be important for the formation of giant epigenetic deposits. The Youjiang basin, SW China, world’s second largest Carlin-type province, but ultimate source its remains enigmatic. In this study, we report that Middle–Late Permian basaltic rocks basin are native grains. These grains scattered interstices pyrite and marcasite amorphous silica cav...

The rapid growth in the demand of embedded systems and the increased complexity of embedded software pose an urgent need for advanced embedded software development techniques. Software technology is shifting toward semi-automated code generation and integration of systems from components. Component-based development (CBD) techniques can significantly reduce the time and cost for developing soft...

Iron occurs mainly as oxide ores, though it is also found in smaller quantities as its sulfide and carbonate. These other ores are usually first roasted to convert them into the oxide. On a world scale the most important ore is haematite (Fe2O3), but in New Zealand the starting materials are magnetite (Fe3O4) and titanomagnetite (Fe2TiO4). The oxides are reduced with carbon from coal, through t...

Abstract Phytomining has been gaining more and popularity in recent years. Scientific information is being accumulated technologies are developed that could make phytomining an applicable technology for the extraction of rare noble metals. In Bulgaria, mining industry well developed. Copper, lead, zinc, gold polymetallic ores mainly mined. The waste generated during process these a great potent...

This study assessed the radiological health hazards to various body organs of workers working within Transnet Precinct in Richards Bay in Kwazulu-Natal, South Africa due to radionuclide content of mineral ores often stored within the facility. Thirty samples were collected from five mineral ores (rock phosphate, rutile, zircon, coal and hematite) and analyzed for 238U, 234U, 226Ra, 210Pb, 235U,...
