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.
Phosphate mining in Nauru involved scrapping off the surface soil and removing the phosphate from between the walls and columns of ancient coral. What remained after mining were tall columns of coral and uneven depressions between them
Now the island faces a double bankruptcy with 90% of the island depleted from mining it faces ecological bankruptcy and with a debt of at least $800 million it faces financial bankruptcy as well. But this is not the end of Naurus problems it now also faces rising sea levels and inland water shortages because of climate change.
The indigenous floras of the raised phosphatic limestone island of Nauru and the atolls of the Gilbert Islands are among the poorest on earth. Long settlement widespread destruction during World War II monocultural expansion of coconut palms and more than 75 yr of opencast phosphate mining in the case of Nauru have led to serious vegetation
The economy of Nauru and Ocean Island has been almost wholly dependent on phosphate which has led to environmental catastrophe on these islands with 80% of the nations surface having been stripmined. The islands phosphate deposits were virtually exhausted by 2000 although some smallscale mining is still in progress on Nauru. Mining ended in 1979 on Banaba.
These problems have led to a decrease in the life expectancy of the islanders which is between 50 and 60 years. (7) The traditional culture of the Unarms has also been affected by the mining of phosphate. German settlers in the late asses prohibited native dancing and native myth suffered as well.
The tiny islandnation of Nauru (pronounced NAHroo) in the western Pacific is the smallest and most remote republic in the world. It also is a case study in humanity's ability to plunder its environment. Located on the equator some 500 km west of its nearest neighbor in the Marshall Islands Nauru has
The phosphate mining carried out partly by Nauru but mostly by Australian and British companies had rendered most of the island both uninhabitable and infertile (about 80% of the surface of the island) by the 1960s leaving everything but the coastal strip uninhabitable (Klein 2014).
