1、内蒙古科技大学毕业设计说明书 I 摘要摘要 根据任务书要求,本次设计任务为日处理量为 5460t/d 的黄沙坪铅锌选矿 厂,产品为铅精矿、锌精矿。 设计首先进行了选址工作黄沙坪铅锌矿厂,详细介绍了黄沙坪选矿厂 的基本情况和矿石的性质,确定了车间工作制度,进行了流程选择计与论证。 最终确定采用三段一闭路破碎流程,磨矿采用一段闭路流程,选别采用部分等 可浮浮选流程,精矿采用二段脱水流程。接着对破碎、筛分、磨矿、分级、选 别、浓缩和过滤等作业进行流程计算和设备选择与计算,并对其设备选择进行 方案比较。根据选矿厂的地形条件,厂房总体布置采用阶梯式配置,粗碎和中 细碎厂房分厂房配置,检查筛分厂房独立配置
2、,磨矿与浮选车间共厂房配置, 浓缩与过滤车间分开配置,浓缩采用露天配置。 本设计绘制了破碎、筛分、磨浮、脱水车间平断面图;设备联系图;数质 量矿浆流程图共 9 张,由计算机 AutoCAD 绘制的。 关键词关键词:选矿厂设计 铅锌矿 部分等可浮流程 内蒙古科技大学毕业设计说明书 II Abstract By following the assignment, my work is to design an 5460t/d lead-zinc concentrators with lead concentrate and zinc concentrate as it s products. Fi
3、rstly, I choose the address of the concentrators and then introduce the basic condition of Huang Sha Ping lead-zinc concentrators and the properties of ore. I choose and demonstrate the process after confirming the workshops system. So, the process of crushing is three sections with one closed circu
4、it; the grinding take the one section closed process. Ore dressing takes process of partly selective flotation in the lead-zinc separation. Dewatering takes two sections circuit with concentrate and filter. The crushing, screening, grinding, classification, ore-dressing, concentration and filter are calculated. Comparing to several different programs, the mineral processing equipments are confirmed. Lastly, according to the topography of Huang Sha Ping, workshops are arranged step
