1、摘要按照毕业设计任务书的要求，进行了会泽铅锌矿3000吨/日选矿厂初步设计，产品为铅精矿和锌精矿。本文在云南省曲靖市会泽铅锌选矿厂收集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：破碎采用三段半开路流程，磨矿采用两段闭路流程，浮选采用优先浮工艺，精矿采用先浓缩后过滤的两段脱水。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）和脱水流程。对破碎、筛分、磨矿、分级、浮选及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，
2、并进行了厂房内的设备配置。根据选厂房的地形条件，沿山坡地布置，其中，粗碎、中细碎、筛分厂房分开布置，粗碎、中细碎及筛分车间平行等高线配置。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。完成了粗碎、中细碎、筛分、磨浮、总平面图、数质量流程图和设备联系图共8张。关键词：选矿厂设计铅锌矿浮选工艺流程VIAbstractAccordingtotherequirementsofthedesignplandescriptionsofthegraduation,theHui-Zele
