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.

CHEMICAL WEATHERING. Like mechanical weathering there are several different types of chemical weathering. One type is oxidation the reaction of oxygen with ironbearing minerals in rock. In an oxidation reaction the iron atom loses electrons and precipitates as another mineral. Perhaps the most wellknown oxidation reaction is the formation of rust. Consider another reaction the oxidation
The iron in olivine (Fe 2 SiO 4) is reduced and the iron in limonite (Fe 2 O 3 .H 2 O) is oxidized. In addition the release of silicon and hydration makes the mineral more susceptible to physical weathering. (Image on the left courtesy of USGS. Image on the right courtesy of ).
Chemical weathering. Profile of weathered sedimentary rocks to limonites and clay minerals. Concepcion Chile. Profile of metamorphic rocks weathered to clay minerals. Coronel Chile. Minerals weather chemically when they react with air and water. In these processes some minerals dissolve and others combine with atmospheric components (mainly water oxygen and carbon dioxide) to form new
Limonite. Chemical weathering changes the composition of rocks often transforming them when water interacts with minerals to create various chemical reactions Chemical weathering is a gradual and ongoing process as the mineralogy of the rock adjusts to the near surface environment New or secondary minerals develop from the original minerals of the rock...
Chemical weathering results from chemical changes to minerals that become unstable when they are exposed to surface conditions. The kinds of changes that take place are highly specific to the mineral and the environmental conditions. Some minerals like quartz are virtually unaffected by chemical weathering while others like feldspar are easily altered.
