文档介绍:摘要
根据任务书要求,本次设计任务为日处理量为80万t/a的黄沙坪铅锌选矿厂,产品为铅精矿、锌精矿。
设计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,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。
关键词:选矿厂设计,铅锌矿,部分等可浮流程
Abstract
By following the assignment,my work is to design an 90t/a lead-zinc concentrators with lead concentrate and zinc concentrate as it `s products.
Firstly,I choose the address of the concentrators and then introduce the basic condition of Huang Sha Ping lead-zinc concentrators and .I choose and demonstrate the process after confirming the workshop’s ,the process of crushing is three sections with one closed circuit;the grinding take the one section closed dressing takes process of partly selective flotation in the lead-zinc takes two sections circuit with concentrate and crushing,screening,grinding,classification,oredressing,
concentration and filter are paring to several different programs,the minneral processing equipments are confirmed to the topography of Huang Sha Ping,workshops are arranged step by crushing is arranged in a unique workshop separated form the mid and fine screening workshop is unique too. There are ten design drawings contained in my work include the tabulate and sectional drawings of crushing,grinding,dewatering;the connection of equipment there is one drawing maken by hand and the others are drawed puter with AutoCAD.
Keywords: mineral processing plant design; lead and zinc ores;partly selective flotation
