摘 要
本次设计以金岭铁矿选矿厂现有的工艺流程为基础，结合其现场资料以
及相关的理论知识，设计一个新的选矿厂。
破碎筛分流程采用两段一闭路流程，原矿直接进入旋回破碎机破碎至
104mm，破碎产物经预先筛分，得到-12mm的产物进入磨矿流程，筛上产物
进行抛尾，精矿进入锤式破碎机，尾矿直接运到尾矿库，锤式破碎机与检查
筛分形成闭路，晒下产物进入磨矿流程。
磨矿分级流程采用一段闭路流程，破碎产物经湿式预选，精矿进入球磨
机，尾矿进入振动筛，筛出-2mm的产物与球磨机产物一起进入螺旋分级机，
分级机的溢流进入选别作业，沉砂则返回球磨机。
选别的原则流程为先浮后磁流程，混合浮选的精矿为铜钴混合精矿，对
此混合精矿进行铜钴分离浮选，得到铜精矿和钴精矿；混合浮选的尾矿进入
磁选，经连续三次磁选后得到铁精矿。
关键词：破磨流程，浮选，磁选。
Abstract
This design is on the basis of existing circuits of Jinling Iron Mine,
combining the on-the-spot data and relevanting theoretical knowledge to design a
new ore-dressing concentrator.
This design use two stages and one closed crushing ore enter into gyratory
crushers directly to product goes to pre-screening to get -15mm mineral,into the
grinding circuit,and the product on the screen is rejected gangue prior to the
second crusher and the screen of checking are to be close-circuit, and the
product under the screen into the grinding process.
The grinding and classification process using one closed crushing circuit.
Broken product is separated by wet caucus, concentrate entering ball mill,and
tailing into the vibrating screen to get -2mm mineral,which goes into the spiral
classifiers with the ball mill overflow of the spiral classifiers enters the sorting
circuit,and the grit is returned to the ball mill.
The principle separated circuits is floating and then mixing floatation
concentrate is the mixture of copper and cobalt,and then separate this mixture to
get copper concentrates and cobalt tailing of mixing floatation enter into the
magnetic separation,iron concentrates is obtained by three magnetic separation
continuously.
Keywords: Crushing and grinding processes circuit, Flotation process, Magnetic
separation.
