Abstract
Main metallic minerals are chalcopyrite,pyrite and tennantite in a gold ore from northeast Jiangxi province.Its conventional cyanidation is difficult.The gold concentrate leaching rate is only 40.34%.The research with rolling bottle,hypoxia biooxidation intensified by magnetic field and leaching gold from biooxidation leavings intensified by magnetic field was carried out.The gold leaching rate is enhanced to 93.21%.
