Gold Ore Processing Sciencedirect

gold mining and processing operations are important sources of arsenic release to the environment. this chapter focuses on the magnitude of the arsenic problem in gold processing and the methods used to mitigate the risk to the environment. the association of gold and copper mineralization in commercially viable ore is a common occurrence gold processing gold processing refining: gold extracted by amalgamation or cyanidation contains a variety of impurities, including zinc, copper, silver, and iron. two methods are commonly employed for purification: the miller process and the wohlwill process. the miller process is based on the fact that virtually all the impurities present in gold combine with gaseous chlorine more technology for mining thin coal seams particularly thin-seam longwall technology, would be beneficial. In view of the extreme difficulties for workers in such a constricted environment the technology for thin-seam longwalls must include as much automation, remote control, and autonomous operation as possible.
