金矿选矿设备生产线配置附流程图及英文

 好的金矿选矿设备生产线配置可以节约成本,有一个高效的回收率,金矿选矿设备生产线以提选精金矿为目的,后通过冶炼制成成品金。选金设备作为矿山机械行业主要的机械设备,其自身质量影响选矿设备的使用寿命,关系着选矿企业的经济效益;而选矿质量的好坏取决于金矿选矿方法以及金矿选矿工艺流程。 
    如何配置金矿选矿设备生产线,才能够提高金矿选矿的产量和质量? 
    金矿根据不同的矿石性质(伴生矿石的不同),采用不同的选矿方法,根据不同方法确定选矿工艺。根据我国金矿资源分布特点,主要有以下几种金矿选矿工艺。   
  1、金矿选矿方法-浮选工艺: 
    我国80%的选金厂采用浮选法选金,产出的精矿多送往有色冶炼厂处理。由于氰化法提金的日益发展和企业为提高经济效益,减少精矿运输损失,多采取就地处理,浮选工艺有较大发展,在选金生产中占有相当的重要地位。 


    2、金矿选矿方法-重选工艺:  
    重力选矿方法是按矿物密度差分选矿石的方法,采用的主要设备有溜槽、摇床、跳汰机和短锥旋流器等。      3、金矿选矿方法-化选工艺: 
    目前的化选方法主要有混汞法提金工艺和氰化法提金工艺。混汞法提金工艺是一种古老的提金工艺,既简便,又经济,适于粗粒单体金的回收,但对于环境有很大的污染,逐渐被重选、浮选和氰化法提金工艺所取代。      4、氰化法提金工艺: 
    包括氰化浸出、浸出矿浆的洗涤过滤、氰化液或氰化矿浆中金的提取和成品的冶炼等几个基本工序。 
    黄金有多种不同的选矿流程,但是大多数情况下都是分为湿选以及干选这两种,由于各种类型的矿物所含的水分含量有不同的要求规则,因此要根据矿物水分的含量进行为适合的金矿选矿设备的选矿方法。 
    如果金矿选矿设备是用湿选法,经由洗砂机水洗,或是浮选机的浮选流程,就使矿物的含水量达到饱和了。由于堆浸法通常情况下都是用去一些低档次的矿石的选矿,在这种情况下的选矿,那些尾矿废石就很少被回收,而且在主要的生产方面,所精选出的物料产量也很低,但是金矿选矿设备的出现很好的解决的这些缺陷,在设备的技术上有了一个质的提升。 
    确定选矿工艺后,金矿选矿工艺的流程也会逐渐清晰,以金矿选金浮选工艺为例,选矿流程主要是:料仓→鄂式破碎机→圆锥破碎机→槽式洗矿机→带式输送机→螺旋分级机→节能球磨机→摇床→自吸气机械搅拌式浮选机→高效浓缩机→浸出槽。

Good mineral processing equipment production line configuration can save cost, a high recovery rate, the gold ore dressing equipment production line for the purpose of selecting fine gold, finally finished gold smelting. As the most important mechanical equipment in the mining machinery industry, the quality of gold dressing equipment affects the service life of the mineral processing equipment, which is related to the economic benefits of the mineral processing enterprises. The quality of the ore dressing depends on the gold dressing method and the process of gold dressing.
How can the production line of gold ore dressing equipment be configured to improve the production and quality of gold mining?
According to different ore properties (the different associated ores), different ore dressing methods are used to determine the beneficiation process according to different methods. According to the distribution characteristics of gold ore resources in China, the main mineral processing techniques are the following.
1, gold ore dressing method - flotation process:
In China, 80% of the gold concentrates are selected by flotation, and the output of the concentrate is sent to the nonferrous smelter. Due to the increasing development of cyaniding and enterprise to improve economic efficiency, reduce concentrate transportation loss, take in situ treatment, flotation process have larger development, occupies an important position in gold production.
2. Gold ore dressing method - reelection process:
The gravity separation method is the method of separating ore according to the density difference of mineral. The main equipment used is chute, rocking bed, jigger and short cone cyclone. 3. Gold ore dressing method - chemical process:
At present, the main method and cyaniding technology of gold amalgamation process. Gold amalgamation process is an ancient gold extraction process, which is simple, economical, suitable for coarse monomer gold recovery, but has great pollution to the environment, has been gradually replaced by gravity separation, flotation and cyaniding process. 4, cyaniding technology:
Some basic processes, such as cyanide leaching, washing and filtration of leaching pulp, extraction of gold in cyanide or cyanide pulp and smelting of finished products, etc.
There are a variety of different gold beneficiation process, but most of the cases are divided into wet and dry separation of the two, because there are different rules of various types of mineral water content contained, so according to the content of mineral water was the most suitable processing method of gold ore dressing equipment.
The water content of the mineral is saturated if the ore dressing equipment is wet selected, washed by the sand washing machine, or the flotation process of the flotation machine. Because heap leaching is normally used to processing some low grade ore dressing, in this case, the tailings and waste rocks were seldom recovered, and in the production of the main, the selection of the material yield is very low, but the gold ore dressing equipment can solve these defects and have a qualitative improvement in equipment technology.
To determine the beneficiation process, the process of ore dressing process of gold will gradually clear, the gold separation flotation process as an example, the beneficiation process is mainly: silo, jaw crusher, cone crusher, tank washer, belt conveyor, spiral classifier, and shaker, energy-saving ball mill self suction flotation machine - high efficiency thickener, leaching.
