Abstract Zinc ion dissolved in water is attempted to be removed by generating the oxides of zinc using oxygen gas dielectric barrier discharge (DBD) plasma system. The removal rate oxides’ production (ZnO and Zn(OH) 2 ) are measured at different treatment periods penetration water. deposit increases initially then decreases with period. maximum (29%) from achieved period 10 min, where pH lower ...

The influence of experimental conditions on the formation of ZnO fibers by electrospinning has been investigated. The electrospinning of a viscous suspension containing polyvinylpyrrolidone and zinc acetate in C2H5OH/H2O produced very long fibers (several hundred μm). Upon calcination a thin deposit of precursor fibers at 400 or 500 °C for 1 h the fibers consisting of ZnO nanoparticles were obt...

Seasonal and spatial variations in metal concentrations and pH were found in a stream at a restored copper mine site located near a massive sulfide deposit in the Foothill copper-zinc belt of the Sierra Nevada, California. At the mouth of the stream, copper concentrations increased and pH decreased with increased streamflow after the onset of winter rain and, unexpectedly, reached extreme value...

Zinc nickel alloy was deposited from alkaline bath at a PH of 13-14 with the nickel percentage of 5-9% in our prior research. Present study dealt with the research on 10-12% of Nickel at a PH of 12-13 from Zinc – nickel alloy electrolyte and the remaining percentage of Zinc, required for corrosion resistant applications to be used for reliable alternative of cadmium. Hull cell studies was carri...

The Huoshaoyun zinc–lead deposit, a giant non-sulfide deposit in Xinjiang, is one of the most significant discoveries China and globally recent years. dominated by non-sulfides, with minor occurrences sulfides such as sphalerite, galena, pyrite. minerals include smithsonite, cerussite, anglesite, Fe-oxide. This study focuses on mineralogical characteristics sulfide ores, well trace element Mine...

The effects of dietary inclusion of freeze-dried goat and cow milk on the utilization of zinc and selenium, and on the metabolic fate of zinc, were studied in transected (control) and resected rats (resection of 50% of the distal small intestine). Intestinal resection reduced the apparent digestibility coefficient and zinc retention in the cow milk diet, whereas these biological indices were si...

Silver Queen mint in central British Columbia, is located approximately 35 kilometres south of Houston and 3 kilometres east of 0wt.n Lake (Figure 2-7-1). Although currently inactive, it was worked briefly in the early 1970s for gold. silver, copper, zinc, lead and cadmium. The deposit is hosted by Cretaceous rocks of the informal Tip Top Hill group (78.322.67 Ma, K-Ar whole rock), with the age...

The ability to produce three-dimensional physical property models of the subsurface from surface geophysical data, coupled with an increasing need to explore for minerals in concealed terranes, results in geophysical inversions providing more significant information to the exploration team. We examine the role that geophysical inversion can play in an integrated mineral exploration program, and...
