Long-term declines in rainfall in south-western Australia have resulted in increased interest in the hydraulic characteristics of jarrah (Eucalyptus marginata Donn ex Smith) forest established in the region's drinking water catchments on rehabilitated bauxite mining sites. We hypothesized that in jarrah forest established on rehabilitated mine sites: (1) leaf area index (L) is independent of in...

For the past decades researchers are showing immense interest to investigate the natural advantage of preparation of composites from minerals such as bauxite particles, and proved their effectiveness as cost effective reinforcing agents in fabrication of high performance composites. This study, is a new attempt in using the Iraqi natural bauxite powder with different proportions (2wt%, 4wt%, an...

Each year, more than 25 percent of highway fatalities in the United States occur at or near horizontal curves, according to the Federal Highway Administration (FHWA). In an attempt to save lives and prevent injuries, some 30 states across the U.S. are applying high friction surfaces (HFS) to improve skid resistance at locations with a high incident of vehicle crashes such as severe horizontal c...

Lithium is one of the secondary mineral elements occurring in bauxite. The behavior lithium-bearing bauxite digestion process was investigated, and effect conditions on extraction rates lithium studied. results demonstrate that mass ratio added CaO to bauxite, KOH concentration, temperature had a significant efficiency. An L9(34) orthogonal experiment demonstrated order each factor for from pri...

The versatility of FTIR spectrometry was explored by considering a variety of samples drawn from industrial applications, materials science and biomedical research. These samples included polymeric insulators, bauxite ore, clay, human hair and human skin. A range of sampling techniques suitable for these samples is discussed, in particular FTIR microscopy, FTIR emission spectroscopy, attenuated...

Abstract Sending microwaves through bauxite ore allows almost continuous measurement of moisture content during offload by conveyor belt from a ship. Data and results microwave analyser were brought to European Study Group with Industry at the University Limerick, over-arching question whether are accurate enough. The equipment uses linear regression against phase shifts signal attenuation infe...

Bauxite formation is usually possible in humid and tropical weather conditions with the enrichment of minerals containing Al2O3 environment. These are found chemical compositions that rich major trace elements, REEs. Karst-type bauxites have different characteristics terms REE elements since they undergo alteration processes. Various correlations can be evaluated using geostatistical methods to...
