and adsorption process are carried out at the same time.

cycle, high automatic level ,high benefit, etc.
• The product of CIL process is gold-loaded carbon，which need to
be dealt by desorption and electrolysis as well as smelting.

Desorption and Electrolysis
The desorption of gold-loaded carbon is essentially the process of replacement of Au
(CN) 2
- on carbon by excess OH- or CN- in desorption solution. In the process of
electrolysis, the gold of the ion state is obtained from the anode plate, and the metal
gold is deposited on the surface of the cathode（carbon fiber or steel wool).
The product of this step is gold slime,with 20-50% of gold and other mentals such as
silver, copper, and so on.
解吸电解：解吸的本质就是载金炭上的Au (CN) 2
- 被解吸液中过量的OH- 或 CN-置换的过程；
电解过程中，离子状态的金从阳极板中得到电子，还原成金属金在阴极（碳纤维或钢毛）表面上
沉积下来。
本步骤的产品为含有20-50%的金以及其他例如银、铜等金属的金泥

• Environmental gold leaching agent：as a kind of low toxicity and environment-friendly
leaching agent, a lot of brands of environmental gold leaching agents leaded by”
JINCHAN” have attracted too much attention in recently years, and widely used in the
gold mine around the world. The way to use this kind of agent is no different than that
way in using sodium cyanide.This is one of the greatest discoveries in gold production
industry
• 环保提金剂：作为一种低毒、环保型的浸出药剂，以“金蝉”为首的环保提金剂，在近年来得到了黄
金生产行业的极大青睐。其不需改变原有浸出流程，既可用于堆浸、也能用于搅拌浸出，浸出液的
处理方式与氰化钠浸出的浸出液的方式一致，在世界上大大小小的黄金生产矿山得到了广泛的应用。

• CILO: when leaching, using pure oxygen or hydrogen peroxide to
replace the compressed air, which can accelerate leaching kinetics,
reduce the leaching time, sometimes it can also increase the
leaching rate of gold and silver; the result of reducing the
consumption of leaching agent is also very good, while leaching the
fine grinding ore, it has better result than compressed air;
• It has obvious results in South Africa Welkom gold metallurgy factory,
Queensland Australia Selwyn mine, Hebei Dongping gold mine,
Zhangjiakou gold mine,and now it is gradually being popularized
and applied.
• 富氧浸出：即在浸出的时候，采用纯氧气或者双氧水代替压缩空气，加速浸
出动力学，减少浸出时间，有时也会增加金银的浸出率；降低氰化物消耗；
• 在南非Welkom金选冶厂、澳大利亚昆士兰州Selwyn矿、河北东坪金矿、张
家口金矿等地取得了较为明显的结果，正在逐步的被推广和应用。

• Adsorption column applied in the CIL process.
• As the water using in the grinding contains a certain grade of
leaching agent, so the leaching action will be carried out at the
grinding process. this result in that the overflow of the thickener will
also has a certain grade of gold. If the overflow can be dealt by the
active carbon in the adsorption column, the gold will be recovered
in time and to avoid the excessive backlog of gold in the water
system, this measure can also reduce the adsorption pressure for the
following steps.
• In total,this application can reduce the gold grade of the tailing
solution and improve the recovery rate of gold.
• 炭浸厂吸附柱的应用：由于磨矿采用的回水中含有一定的浸出药剂成分，在
磨矿的过程当中，浸金反应就已经开始发生，因此浓密机溢流水中也就存在
一定品位的金，如果将浓密机溢流水经过吸附柱中的活性炭吸附过后，可以
及时的回收金，避免水系统中积压过多的金，也能降低吸附作业阶段的吸附
压力，达到降低尾液提高金的回收率的作用。

• Resin Adsorption Method（RIL）:
• The gold absorption resin is used to adsorpt the gold instead of
activated carbon, it has the advantages of high adsorption
capacity, no wear and strong selectivity,and so on. However, due to
the complexity of the subsequent treatment and high price, the
price performance ratio is low,and has not been used too much, but
of course it will get more applications with the progress of science
and technology.
• 树脂提金法：该法采用吸金树脂替代活性炭，具有吸附容量高，不产生磨损，
吸附选择性强等优点，但由于后续处理复杂，价格高昂等原因，性价比偏低，
但随着科技的进步，它一定会得到更多的应用

separated from the surface oxidizing ore,and the tailing is the raw ore for the
heap leaching.After adding cement and pelletized, the raw ore is transported to
the heap leaching field by the belt conveyors. and then the solution containing
sodium cyanide is dripped onto the ore heap, and permeate down, finally flow
out with the dissociated gold from the lower part of the heap. the solution will be
treated by CIC system,and the gold will be absorbed by the active carbon, then
sent to the desorption and electrolysis system.
