beneficiation process arsenic in mongolia

Residents of the Bayingnormen region of Inner Mongolia have been exposed to arseniccontaminated well water for over 20 years but relatively few studies have investigated health effects in this region We surveyed one village to document exposure to arsenic and assess the prevalence of arsenicassociated skin lesions and selfreported morbidity

Aug 01 2004 · The concentration of arsenic in these deep wells increases with decreasing elevation The population at risk has increased to more than 100 000 while more than 2000 persons have been diagnosed as having arsenicosis In 1989 the Inner Mongolia was reported as another endemic area of severe arsenicosis in China

In recent years health officials in Hangjin Hou like other arsenic affected areas of Inner Mongolia have focused on improving water quality and reducing arsenic exposures In this study water arsenic levels were lower than previously documented 428 and few subjects were exposed to over water over 100 μgL Despite these relatively moderate water arsenic exposures we observed

A positive correlation of arsenic copper and cadmium is observed in the flotation process • Arseniccopper alloys in FSF slag account for nearly 90 of arsenicbearing phases • Different fates of arsenic are depended on its embeded ways • The recombination of AsO and CuS affects the selectivity of copper and arsenic

Aug 23 2013 · Most of the risk centers in a few provincesXinjiang Inner Mongolia Henan Shandong and Jiangsubut the total population exposed to arsenic levels above 10 micrograms per liter could be upwards of 19 million people Arseniccontaminated groundwater used for drinking in China is a health threat that was first recognized in the 1960s
