摘　　要：研究猪油、淀粉和鸡蛋3种酵解液与磁黄铁矿、黄铁矿间的相互作用。结果表明3种酵解液水溶性有机物群中,因某些有机物质的活性的存在而与氧化状态中硫化矿粉间有明显的相互作用,其反应代表性的产物是CS2,还有少量COS等小分子有机物。3种有机酵解液水溶性有机物质中最有代表性的共性功能团是羰基(醛、酮、酸、酯的),羰基的亲电性可能有利于与氧化态的硫化矿中的亲核性硫相互作用。The interreactions of sulfide ore （pyrrhotite.and pyrite） and fermentation broth of lard oil, starch and egg are investigated. The results show that three kinds of fermentation broth obviously react with oxidized sulfide ore since there are various kinds of organic compounds in the fermentation broth. The typical reaction product is CS2, and a few of small molecule organic compounds are also formed, such as COS etc. The main functional group of the organic compounds is carbonyl（aldehydes, ketone, acids, ester and so on） in the three fermentation broth. May be the properties of electrophilic of the organic compounds and the nucleophic of sulfides can be incorporated to carbon disulfide.
