A classifier equipment with overflow end spiral completely submerged below the liquid surface.
Xinhai tailings dry stacking technology is mainly applied to the dewatering and concentrating of mineral tailings in the mineral processing plants. To reach the aim of tailings dry stacking and avoiding environmental pollution, it is the essential technology of green mine.
Phosphate Flotation Product Line is applied for complex structure phosphate with fine particle distribution, closed embeddedness relationship, difficult monomer dissociation, etc.
Barite is fragile and like a big tube. The separation methods of Xinhai are generally gravity separation, magnetic separation and flotation.
Alluvial gold processing solution mainly applies to processing alluvial gold with a large volume of gangue minerals. Alluvial gold processing is a set of mining processes, including crushing and screening, desliming stage, separating stage, etc.
Cadmium is a byproduct of zinc lead and copper mining and smelting operations. Long used in pigments and as an anticorrosive cadmium has been increasingly phased out of most products like paints where normal wear and tear eventually releases it to the environment.
Cadmium copper alloys are considered high copper alloys they contain approximately 98 99 % copper 0.1 1.5% cadmium and sometimes minor amounts of other materials. When cadmium is added to copper the material becomes more resistant to softening at elevated temperatures.
Cadmium is produced mainly as a byproduct of mining smelting and refining of zinc and to a lesser degree as a byproduct of lead and copper manufacturing. Most of the cadmium produced is used in the production of nickelcadmium batteries which in 2004 represented 81 per cent of the total amount of cadmium.
principal uses of cadmium in 2007 were nickel cadmium (NiCd) batteries 83% pigments 8% coatings and plating 7% stabilizers for plastics 1.2% and other (includes nonferrous alloys semiconductors and photovoltaic devices) 0.8% (USGS 2008). Cadmium is also present as an impurity in nonferrous metals (zinc lead and copper) iron
highest concentrations (dry weight) recorded were cadmium (0.21 ± 0.03 µg g1) and lead (1.67 ± 0.26 µg g 1) in S. rectifraenum copper (1.60 ± 0.49 µg g1) and zinc (67.30 ± 8.79 µg g ) in B. polylepis and iron (27.06 ± 2.58 µg g1) in K. vaigiensis. Our findings show that each element accumulates
