黄金提炼过程：
1.混汞法提金
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。我国不少黄金矿山还沿用这一方法。随着黄金生产的发展和科学技术进步，混汞法提金工艺也不断得到了改进和完善。由于环境保护要求日益严格，有的矿山取消了混汞作业，为重选、浮选和氰化法提金工艺所取代。在黄金生产中，根据矿石性质改为混汞加浮选联合流程，总回收率提高7.81%(混汞回收率达64.6%)，尾矿品位由0.74g/t降到0.32g/t，年获效益为158万元。混汞法提金工艺关键在于如何采取防护措施，消除汞毒污染。
 2.氰化法提金工艺　

 氰化法提金工艺是现代从矿石或精矿中提取金的主要方法。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。我国黄金矿山现有氰化厂基本采用两类提金工艺流程，一类是以浓密机进行连续逆流洗涤，用锌粉置换沉淀回收金的所谓常规氰化法提金工艺流程（CCD法和CCF法），另一类则是无须过滤洗涤，采用活性炭直接从氰化矿浆中吸附回收金的无过滤氰化炭浆工艺流程(CIP法和CIL法)。

椰壳活性炭的吸附性能影响因素：

活性炭的吸附能力与水温的高低、水质的好坏等有一定关系。水温越高，活性炭的吸附能力就越强；若水温高达30℃以上时，吸附能力达到极限，并有逐渐降低的可能。当水质呈酸性时，活性炭对阴离子物质的吸附能力便相对减弱；当水质呈碱性时，活性炭对阳离子物质的吸附能力减弱。所以，水质的PH不稳定，也会影响到活性炭的吸附能力。

椰壳活性炭注意事项： 　　

1、运输与装卸：活性炭在运输过程中，不得用铁钩拖拽，应防止与坚硬物质混装，不可强烈振动、磨擦、踩、砸，严禁抛掷，应轻装轻卸，以减少炭粒破碎，影响使用。

2、储存：应储存于阴凉干燥处，防止内外包装袋破裂，防止受潮和吸附空气中其它物质，影响使用效果。严禁与有毒有害气体或易挥发物质混放，存放要远离污染源。

3、严禁水浸：活性炭属于多孔性吸附类物质，所以在运输、储存和使用过程中，都要绝对防止水浸，因水浸后，水填充了活性孔隙，减少了活性炭比表面与气体的直接接触，严重影响使用效果。

4、防止焦油类物质：在使用过程中，应禁止焦油类粘稠物质进入活性炭床，以免堵塞活性炭孔隙或遮盖了活性炭展开表面，使气体不能与活性炭展开表面接触，失去应用效果，如气体中含有此类物质，应在气体进入活性炭床前进行清除（最好有除焦设备）以达到好的应用效果。

5、防火：活性炭在储存或运输时，防止与火源直接接触，以防着火。活性炭再生时避免进氧并再生彻底，再生后必须用蒸气冷却降至800℃以下，否则温度高，遇氧，活性炭自燃。

6、使用：装填时应先筛去因搬运产生的碎粒与粉尘。然后层层均匀铺开，不得从进料孔处直接倒入，以免使大小颗粒装填不均，最终造成气体偏流，影响使用效果。装填结束，开车前应先吹空，吹出活性炭表面粘附粉尘，避免开车后粉尘带入后工段而影响正常生产。

7、安全需知：湿的活性炭需要从空气中除去氧，在安全密闭的容器内氧的消耗会造成有毒的环境，假如工人进到含有活性炭的容器内适当取样或低含氧空间作业，应遵守国家相关标准及作业规范。

Gold refining process:

1. The amalgamation of leaching gold

Amalgamation amalgamating technology is a kind of ancient amalgamating process, which is simple, and economic, suitable for coarse monomer gold recovery. A lot of gold mines in our country still continue to use this method. With the gold production and the development of science and technology progress, amalgamation amalgamating process also constantly improving and perfecting. Due to the environmental protection requirements increasingly strict, some mine cancelled amalgamated homework, as heavy choose, flotation and leaching gold cyanidation replaced process. In the gold production, according to the ore properties to amalgamated and flotation combined process, the total recovery rate is 7.81% (amalgamated recovery 64.6%), tailings grade from 0.74 g/t to 0.32 g/t, the benefit for 1.58 million yuan. Amalgamation amalgamating technology the key lies in how to take protective measures to eliminate the mercury poison pollution.

2. Cyanidation amalgamating process

Cyanidation leaching gold from ore is the modern technology to extract gold or concentrate the main method. Cyanation amalgamating process include: cyanide leaching, leaching pulp washing filtering, cyanide liquid or cyanide pulp zhongjin extraction and finished products such as smelting several basic process. China s gold mine existing cyanide plant basic using two kinds of amalgamating process, one kind is a thickener for continuous countercurrent washing, with dust replacement precipitation gold recovery of so-called conventional cyanidation amalgamating process (CCD method and CCF method), the other is without filter washing, using activated carbon adsorption directly from cyanide pulp in the recovery of gold no filter cyaniding carbon plasma process (CIP method and CIL method).

Coconut shell activated carbon adsorption performance influence factors:

Activated carbon adsorption capacity and the water level, water quality and so on have particular concern. The higher the temperature, activated carbon adsorption ability is stronger; If the water temperature as high as more than 30℃, the adsorption capacity the reaching of the limit, and gradually reduce the possible. When water is acidic, activated carbon adsorption ability of anion material and relative weakening; When water is alkaline, activated carbon adsorption ability of cation material weakened. So, the quality of the PH is not stable, will also affect the activated carbon adsorption ability.

Coconut shell activated carbon note:

1, transport and handling: activated carbon in the transport process, shall not use the iron hook drag, should prevent and hard material conventional, not strong vibration, friction, step on it, is strictly prohibited, casting, should be light light discharge, in order to reduce carbon grain crushing, the influence is used. 2, storage: should be stored in a cool and dry place, prevent inside and outside packing bag burst, prevent moisture and adsorption air other material, the influence is used effect. With no toxic or harmful gases or volatile substances readjusting, deposit to stay away from pollution. 3, it is strictly prohibited to water immersion: activated carbon belong to the porous adsorption kind material, so in the transportation, storage and use process, will absolutely prevent water immersion, due to flooding, water filling the active pore, reduce the activated carbon surface and gas than the direct contact, the serious influence use effect. 4, prevent tar class material: in use process, should be prohibited from tar kind of viscous material into the activated carbon bed, lest jam activated carbon pore or cover the activated carbon on the surface, make gas can t and activated carbon on the surface contact, lose application effect, such as gas contains such material, should be in gas into activated carbon bed remove (had better have decoking equipment) in order to achieve good application effect. 5, fire: activated carbon in storage or transportation, prevent direct contact with fire, in case of fire.
