选矿生产线是由给料机、颚式破碎机、反击破、球磨机、螺旋分级机、高频筛、搅拌桶、浮选机、浓缩机、过滤机、烘干机等设备组成。
选矿工艺流程介绍：选矿设备工艺流程是指开采的矿石要经过各个作业 ,最后得到符合冶炼要求的精矿的生产过程。选矿设备工艺流程主要包括：矿石经破碎机破碎与振动筛筛分、球磨机磨矿与分级机分级；矿物质选别，如重选、浮选与电选等；矿物质脱水，包括浓缩、过滤、干燥等生产流程。选矿设备包括给料机、破碎机、球磨机、分级机、振动筛、摇床、磁选机、搅拌筒、浮选机等设备。
选矿工艺流程如下：开采的矿石先由颚式破碎机进行初步破碎，在由破碎机破碎至合理细度后经由提升机、给矿机均匀送入球磨机，由球磨机对矿石进行粉碎、研磨。经过球磨机研磨的矿石细料进入下一道工序：分级。螺旋分级机借 助固体颗粒的比重不同而在液体中沉淀的速度不同的原理，对矿石混合物进行洗净和分级。经过洗净和分级的矿物混合料在经过磁选机时，由于各种矿物的比磁化系数不同，经由磁力和机械力将混合料中的磁性物质分离开来。经过磁选机初步分离后的矿物颗粒在被送入浮选机，根据不同的矿物特性加入不同的药物，使得所要的矿物质与其他物质分离开。在所要的矿物质被分离出来后，因其含有大量水分，须经浓缩机的初步浓缩，再经烘干机烘干，即可得到干燥的矿物质。

Processing line is a feeder, jaw crusher, counter break, ball mill and hierachial machine, high-frequency sieve, mixing barrel, the flotation machine, the inspissation machines, filter, dryer, etc equipment composition.
Beneficiation process is introduced: milling equipments process means mining ores must pass through each homework, resulting in accord with the requirement of smelting ore concentrate production process. Milling equipments process mainly includes: ore by crusher and vibrating sieve, ball mill grinding and sorting machine grading, Minerals and sorting, such as re-election, the flotation and electricity are selected, etc; Minerals dehydration, including condensed, filtration, drying production process. Milling equipments including feeding, crusher, ball mill and sorting machine, vibrating screen and wave bed, magnetic separators, mixing canister, the flotation machine equipments.
Beneficiation process is as follows: mining ores first by the jaw crusher, preliminary broken by crusher to a reasonable fineness after upgrading machines, gives the ore via evenly into the ball mill, the machine, the ball mill for ore crushing, grinding. After the ball mill grinding ore fine material into the next procedure: grading. Hierachial machine borrow help of solid particles in the liquid proportion of different and the speed of the precipitation in different principle of minerals are washed and classification of mixture. After rinse and classification of the mineral mixture after magnetic separation machine, because all kinds of minerals, through different magnetization coefficient than magnetic force and mechanical force will mixture of magnetic not-as-bad. After magnetic separators preliminary after the separation mineral grains in was sent into the flotation machine, according to different mineral properties of join different drugs, make to the minerals and other material isolates. Desire to the minerals were isolated, because its contains a large number of moisture, subject to inspissation machines preliminary enrichment, then after the dryer drying, you will get dry minerals.General mineral dressing method of processing methods
