Seaweed glue as a novel polymer depressant for the selective separation of chalcopyrite and galenaXiong Chen,Guo-hua Gu,Zhi-xiang ChenSchool of Minerals Processing and Bioengineering, Central South University摘 要:The use of seaweed glue(SEG) as a novel polymer depressant for the separation of chalcopyrite from galena with butyl xanthate(BX......
that the isolate belongs to the genus Acidiphilium. Strain PJH has the capability of leaching chalcopyrite. Bioleaching experiments show that it can improve the leaching rate of chalcopyrite by 10.3% when mixed with L. ferriphilium YTW315 after 35 d. Strain PJH has the potential in application to bioleach chalcopyrite with other mesophilic leaching microbes. Key words: isolation; Acidiphilium sp......
