1、摘要本设计按照毕业设计任务书的要求，进行了柴山铅锌矿2500吨/日铅锌选矿厂初步设计，产品为铅精矿和锌精矿。通过在湖南郴州的柴山铅锌厂进行的为期三周的毕业实习，收集相关设计资料的基础上，确定各车间的工作制度，对设计工艺流程进行了选择和论证，确定了破碎采用三段一闭路流程，磨矿采用两段两闭路流程，浮选采用优先浮工艺，精矿采用先浓缩后过滤的两段脱水的工艺流程。对设计工艺流程进行了数质量和矿浆流程计算，对选矿厂主要工艺设备进行了选择计算和选型。设计也进行了厂房总体布置和厂房内的设备配置。根据地形条件，粗碎、中细碎、筛分厂房分厂房布置，磨矿浮选共厂房配置，其中磨矿
2、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。完成了粗中细碎筛分、磨浮、脱水车间平断面图、数质量及矿浆流程图和总平面共6张图纸的绘制,其中包括一张手工图。本设计还对选矿厂的建筑、供水、供电进行了规定，并进行了选矿厂的技术经济概算，经概算柴山铅锌矿2500吨/日铅锌选矿厂基本建设投资总额为17989.2万元，精矿销售成本为46256.3万元，年利润为14991万元，静态投资偿还期为1.24年。关键词：柴山铅锌矿；初步设计；计算机辅助设计ABSTRACTAccordingtotherequestoftheintruction
