氰化处理

Depending on the characteristics of the low grade oxidized ore on the surface in Woxi,and by small scaled column leaching tests and commercially scaled heap leaching tests,a flowsheet of heap leaching-carbon adsorption-disadsorption and electrowinning was applied,where masking agent was used to reduce the influence of Arsenic and antimonial on cyanidation.

根据沃溪区低品位地表氧化矿矿石的性质特点，通过小型柱浸试验和堆浸工业试验，采用堆浸—活性炭吸附—解吸电解工艺处理该矿石，工艺中采用隐蔽剂以消除砷、锑矿物对氰化的影响，金回收指标较好，经济效益可观。

Toward this end, the olefin 51 was treated with cyanogen azide and, indeed, produced the ring expanded ketone 52

为了证明这一看法，他用氰化迭氮处理烯烃(51)就得到扩大的环酮。

Direct cyanidation will be taken and roasting process will not be necessary after removal of arsenic.

In order to investigate theinfluence of nitrogen on the transformation characteristics, carburized samples with prac-tically the same carbon content as the cyanided ones were also prepared and examined.

为了探索氮对过冷奥氏体转变特性的影响，还将这两种钢进行了固体渗碳处理，使渗碳试样具有和高温氰化试样实际上相同的含碳量，然后将二者进行了平行试验。

Carburizing, cyaniding, and induction hardening are some of the processes commonly used to produce the case hardening effect.

碳化、氰化、感应淬火是局部淬火中经常使用的处理方法。

Application of calcium peroxide has become wider and wider.It was not only used in the fields of rice direct sowing,edible fungus production,soil improvement,aquiculture,wastewater treatment,chemical production,and air purification etc.,but also it has been used as food and feed additive,fruit and vegetable preservative,assisting agent for gold extraction by cyanidation and so on.

过氧化钙可用于水稻直播、食用菌生产、土壤改良、水产养殖、污水处理、化工生产与空气净化等领域，可用作食品和饲料添加剂、水果和蔬菜保鲜剂、氰化法提金助剂等，有着越来越广泛的用途。

NOVELTY - Alkali chemicals are added to the cyanogen group gold-containing liquid, to obtain an alkaline liquid. Zinc is added to the alkaline liquid, and the formed deposit is dissolved in aqua regia. A reducing agent is added to the deposit solution and a deposit is produced. Gold is then separated by heat-processing the deposit.

本发明的新颖性在于：将碱性化学物质添加到氰化含金液中，以获取碱液；将锌加入到碱液中，并将形成的沉积物溶解到王水中；然后在沉积溶液中加入一种还原剂，形成新的沉积物；最后通过加热处理沉积物来分离金。
