1、日处理3500t某铅锌矿选矿厂设计摘要：按照毕业设计任务书的要求，进行了某铅锌矿优先浮选3500吨/日选矿厂设计，产品为铅精矿和锌精矿。在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：破碎采用三段一闭路流程，磨矿采用一段闭路流程，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，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。根据选厂房的地形条件，沿山坡地布置，其
2、中，粗碎、中细碎厂房分开布置，粗碎、中细碎厂房平行等高线配置。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、磨浮车间平断面图、数质量及矿浆流程图和设备联系图。关键词：选矿厂设计铅锌矿浮选110Alead-zincuflotation3500ton/dayconcentratorwasdesignedAbstract：Inaccordancewiththerequirementsofthegraduationdesigntaskbook,alead-zincuflotation3500ton/dayconc
