唐山拓新电器有限公司金厂峪选矿厂设计说明书I摘要在毕业设计中我设计年处理30万吨金厂峪金矿选矿厂。我所毕业设计的选矿厂矿石类型为金矿,采用浮选的方法进行选别。设计的流程为:破碎采用两段一闭路流程,一段磨矿,一次粗选,两次精选,两次扫选。主要选用的设备有破碎机,磨矿机,过滤机,分极机,浮选机,等等。选用设备的原则是确保高品位和高回收率。经过浮选后,精矿品位可达到120g/t,回收率为90%。所以设计的选矿厂是合理的。同时,通过经济计算判断设计的可行性。,,选厂总定员116人,,,。关键词:选矿,破碎,磨矿,,-minution,onestategrinding,onestaterougher,twostatecleaner,,grinder,filter,classifier,,theconcentrategradecanget120g/%.Sothedesignoffactory—,,Itincludes:putationofthetechnicalprocess;putationofmainequipmentsandtheauxiliaryequipments;Plantheinstallationdiagramofmillandthedispositionchart;putationandanalysisoftechnicaleconomy;pilationoftheinstructionbookletKeyword:Mineralprocessing,Crush,Grind,Flotation河北理工大学毕业设计目录1目录摘要........................................................................................................................................IAbstract..................................................................................................................................II1引言..........................................................................................................................................................................................................................................................................................................................................................................................................
