1、年处理60万吨原矿某锰矿选矿厂设计摘要:按照毕业设计任务书的要求,进行了年处理60万吨原矿某锰矿选矿厂设计,产品为锰精矿,要求锰的回收率都大于76.6%,精矿含水量小于3%的选矿厂设计。 在收集湘潭某锰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,一次扫选,三次精选的流程作业)。锰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
2、脱水设备进行了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。完成了选矿厂平面布置图,选矿厂设备平面布置图(示意图),工艺流程图,全厂设备形象系统图和数质量、矿浆流程图共5张。 关键词:选矿厂设计 锰矿 浮选 600000 tons of ore dressing plant design, processing of manganese mine Abstract: Ac
3、cording to the graduation design task book requirements, carried out 600000 tons of ore dressing plant design of manganese ore processing, products for the manganese concentrate, manganese recovery are required to reach 76.6%, concentrate moisture content less than 3% of the design of concentrator.
4、Based on the collection of a manganese mine in XiangaTan concentrator design data, each workshop working system was determined, the selection and verification of the design process, process flow, determine the design is broken by three: a closed-circuit grinding process, using a check for grading of
5、 the grinding process, using a flotation a circular flotation process (including one roughing, one scavenging, three cleaning process operation). Manganese concentrate by two stages of dehydration process to concentrate filtering. The design process is a process of calculation, including crushing, s
6、creening, grinding, flotation (including the pulp flow). The crushing, screening, grinding, classification, flotation and dewatering equipment selection calculation and scheme comparison, process equipment required for the process to determine the.
