1、年处理50万吨原矿某铜矿选矿厂设计摘要:按照毕业设计任务书的要求,进行了年处理50万吨原矿某铜矿选矿厂设计,选矿产品为铜精矿,要求铜的回收率达到85%,铜精矿的含水量小于10%。在收集云南某铜矿选矿厂相关设计资料的基础上,确定了各车间的工作制度,对设计工艺流程进行了选择和论证,确定了设计的工艺流程,即:破碎采用三段一闭路流程,磨矿采用检查分级的一段磨矿流程,浮选采用一段一循环浮选工艺(包括一次粗选,二次扫选,三次精选的流程作业)。铜精矿采用先浓缩后过滤的两段脱水工艺流程。对设计工艺流程进行了工艺指标计算,包括破碎、筛分、磨矿、浮选(包括矿浆流程)。对破碎、筛分、磨矿、分级、浮选及脱水设备进行了
2、选择计算和方案比较,确定了工艺所需的工艺设备。进行了厂房总体布置,并进行了厂房内的设备配置。根据选厂的地形条件,沿山坡地布置,其中,粗碎、细碎、筛分厂房共厂房配置。磨矿浮选共厂房配置,其中磨矿采用纵向配置,浮选机采用横向配置。浓缩机配置在露天,过滤机与精矿仓配置在厂房内。完成了破碎筛分、磨浮、脱水车间平断面图、数质量矿浆流程图,选矿工艺流程图,设备联系图共6张。 关键词:选矿厂设计 铜矿 浮选 iThe Design of one Copper Ore Concentrating Mill with Capacity of 500,000 t/aAbstract: According to t
