The way to use this kind of agent is no different than that way in using cyanide sodium. 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。 能赚钱的石头才是矿！ The Profitable Rock is Ore!

Some New Applications on Leaching 浸金的一些新应用 2 • 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。 能赚钱的石头才是矿！ The Profitable Rock is Ore!

Some New Applications on Leaching 浸金的一些新应用 3 • 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。 能赚钱的石头才是矿！ The Profitable Rock is Ore!

Some New Applications on Leaching 浸金的一些新应用 4 • 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 cause 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 能赚钱的石头才是矿！ The Profitable Rock is Ore!
