金礦選礦設(shè)備生產(chǎn)線配置附流程圖及英文

 好的金礦選礦設(shè)備生產(chǎn)線配置可以節(jié)約成本,有一個高效的回收率,金礦選礦設(shè)備生產(chǎn)線以提選精金礦為目的,后通過冶煉制成成品金。選金設(shè)備作為礦山機(jī)械行業(yè)主要的機(jī)械設(shè)備,其自身質(zhì)量影響選礦設(shè)備的使用壽命,關(guān)系著選礦企業(yè)的經(jīng)濟(jì)效益;而選礦質(zhì)量的好壞取決于金礦選礦方法以及金礦選礦工藝流程。 
    如何配置金礦選礦設(shè)備生產(chǎn)線,才能夠提高金礦選礦的產(chǎn)量和質(zhì)量? 
    金礦根據(jù)不同的礦石性質(zhì)(伴生礦石的不同),采用不同的選礦方法,根據(jù)不同方法確定選礦工藝。根據(jù)我國金礦資源分布特點,主要有以下幾種金礦選礦工藝。   
  1、金礦選礦方法-浮選工藝: 
    我國80%的選金廠采用浮選法選金,產(chǎn)出的精礦多送往有色冶煉廠處理。由于氰化法提金的日益發(fā)展和企業(yè)為提高經(jīng)濟(jì)效益,減少精礦運輸損失,多采取就地處理,浮選工藝有較大發(fā)展,在選金生產(chǎn)中占有相當(dāng)?shù)闹匾匚弧?nbsp;


    2、金礦選礦方法-重選工藝:  
    重力選礦方法是按礦物密度差分選礦石的方法,采用的主要設(shè)備有溜槽、搖床、跳汰機(jī)和短錐旋流器等。      3、金礦選礦方法-化選工藝: 
    目前的化選方法主要有混汞法提金工藝和氰化法提金工藝?;旃ㄌ峤鸸に囀且环N古老的提金工藝,既簡便,又經(jīng)濟(jì),適于粗粒單體金的回收,但對于環(huán)境有很大的污染,逐漸被重選、浮選和氰化法提金工藝所取代。      4、氰化法提金工藝: 
    包括氰化浸出、浸出礦漿的洗滌過濾、氰化液或氰化礦漿中金的提取和成品的冶煉等幾個基本工序。 
    黃金有多種不同的選礦流程,但是大多數(shù)情況下都是分為濕選以及干選這兩種,由于各種類型的礦物所含的水分含量有不同的要求規(guī)則,因此要根據(jù)礦物水分的含量進(jìn)行為適合的金礦選礦設(shè)備的選礦方法。 
    如果金礦選礦設(shè)備是用濕選法,經(jīng)由洗砂機(jī)水洗,或是浮選機(jī)的浮選流程,就使礦物的含水量達(dá)到飽和了。由于堆浸法通常情況下都是用去一些低檔次的礦石的選礦,在這種情況下的選礦,那些尾礦廢石就很少被回收,而且在主要的生產(chǎn)方面,所精選出的物料產(chǎn)量也很低,但是金礦選礦設(shè)備的出現(xiàn)很好的解決的這些缺陷,在設(shè)備的技術(shù)上有了一個質(zhì)的提升。 
    確定選礦工藝后,金礦選礦工藝的流程也會逐漸清晰,以金礦選金浮選工藝為例,選礦流程主要是:料倉→鄂式破碎機(jī)→圓錐破碎機(jī)→槽式洗礦機(jī)→帶式輸送機(jī)→螺旋分級機(jī)→節(jié)能球磨機(jī)→搖床→自吸氣機(jī)械攪拌式浮選機(jī)→高效濃縮機(jī)→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.
