Non-traditional stable isotope systems are increasingly used to study micronutrient cycling and acquisition in terrestrial ecosystems. We previously proposed for zinc (Zn) a conceptual model linking observed signatures fractionations biogeochemical processes occurring the rice soil environment we suggested that 2’deoxymugineic acid (DMA) could play an important role during of Zn when grown unde...

Hematite, the mineral that gives color to bright red iron ochres, occurs naturally, but there is much evidence early humans sometimes artificially produced hematite by heating a related mineral, goethite, in wood fires. This represents an important cognitive and technological advance human prehistory. Thus, need distinguish natural from generated goethite fire. Measuring line widths of powder X...

In this study, grinding + flotation experiments were performed on the sample of complex Pb-Zn sulphide ore taken from Niğde (Ulukışla-Madenköy) region in Turkey. According to mineralogical analysis used experimental studies, it was determined that composition contains calcite, quartz, pyrite, chalcopyrite, hematite, goethite, limonite, gypsum, galena, sphalerite, jarosite, arsenopyrite and marc...

The ironmaking process in blast furnaces using iron lumps is an energy-efficient and low-carbon initiative that helps lower the cost of process. physical chemical properties raw materials, mineralogy, metallurgical three Malaysian ore were researched this paper, with goal showing relationship between qualities mineralogy. results show lump A has a better decrepitation index, DI−6.3mm only 0.2%;...
