The search for alternatives that minimize the generation of tailings and enable their reuse, leads to characterization studies with objective a better understanding physical, chemical mineralogical properties iron ore tailings. increase in demand high-quality overlapping extraction increasingly lower concentration levels, is part challenge mineral exploitation. In view aforementioned needs, mor...

magnetic lignocellulosic fibers have good potential in applications such as information storage, security papers, electromagnetic shielding and etc. in this study unbleached bagasse fibers were used to fabricate magnetic paper by chemical co-precipitation method. lumen loading and precipitation of magnetic nanoparticles on the surface of fibers were carried out by in situ synthesis. then the fo...

To investigate the acquisition mechanism of high and stable natural remanent magnetization (NRM) in rocks of the Russell Belt, Adirondack Mountains, New York, we examined the exsolution microstructures and compositions of magnetic minerals using three samples with different magnetic properties. The samples contain titanohematite with ilmenite lamellae, end-member hematite without lamellae and r...

In the present study, leaching behavior of scandium from limonitic laterites under sulfation roasting–water (SAL) was explored. The mineralogical analysis showed that associated with iron phase. roasting temperature played an important role in phase conversion during process. With increase 100 to 800 °C, (goethite, magnetite, and hematite) gradually converted monoclinic Fe2(SO4)3 (400 °C), then...

Abstract Magnetite stability in ultramafic systems undergoing subduction plays a major role controlling redox states of the fluids liberated upon dehydration reactions, as well residual rocks. Despite their relevance for evaluation conditions, systematics and geochemistry oxide minerals have remained poorly constrained subducted Here, we present detailed petrological geochemical study magnetite...

Alkali-silica reaction (ASR) is considered as a potential aging-related degradation phenomenon that might impair the durability of concrete in nuclear containments. The objective of this paper is the application of digital analysis of microscopic images to identify the content and size of quartz grains in heavy mineral aggregates. The range of investigation covered magnetite and hematite aggreg...

The rare earth elements (REE) possess a beneficial combination of chemical and physical properties, making them valuable for most advanced branches engineering technology. Alternative sources REE are desirable due to limited reserves conventional containing minerals over the world combined with disproportionate supply demand in commodity markets. This study investigated occurrence carbon nanotu...

[1] Paleomagnetic studies of the 91 Ma Ecstall pluton and other Cretaceous plutons of British Columbia imply large northward tectonic movements (>2000 km) may have occurred during the tectonic evolution of western North America. However, more recent studies have shown that the eastern edge of the Ecstall pluton experienced considerable mineralogical changes as younger Eocene plutons, such as th...
