氰化法

For a long time,the extraction of gold composition from gold-ore was generally to use the methods of mercurization or cyanidation etc..

长期以来，黄金成分从含金原料中的提取，通常都是应用传统的混汞法或氰化法等方式。

Various technologies of cyanidation have been studied systematically for gold extraction from a low copper-containing ore.

首先研究了铜矿物类型对金氰化浸出的影响，提出了氰化易溶铜的概念，结果表明，当浸出原料中氰化易溶铜含量大于0.1％时就不适于采用直接氰化法提金。

"Cyanide process: or MacArthur-Forrest process, Method of extracting silver and gold from their ore s by dissolving them in a dilute solution of sodium cyanide or potassium cyanide."

氰化法：亦称麦克阿瑟－福莱斯特法，是将含金和银的矿石溶解于氰化钠和氰化钾稀溶液中，以提取金和银的一种方法。

The productions of glycin oxidation are complicated and the cost is high. The cyanogenesis is poisonous and unsafe.

国内外合成羟基乙酸的方法主要有甘氨酸氧化法、氰化法、醛类羧化法、甲醛和甲酸甲酯偶联法、草酸电解法、氯乙酸水解法等。

The major methods involved in this paper are cyanidation,thiocarbamide process,thiocyanate process,thiosulfate process, multi-sulfide process,haloid process,and other reagents procss;the advantages and disadvantages of the methods as well as the suitability of these methods for treating various silver bearing ores are generally analyzed.

综述了国内外关于银浸出技术的各种方法，主要内容包括氰化法、硫脲法、硫氰酸盐法、硫代硫酸盐法、多硫化物法、卤化物法和其他试剂法等，简要分析了各种方法适用的含银矿石及其利弊。

Adopting this craft to produce the inferior gold potassium of cyaniding,it is reliable that the craft is simple,the production process is easy to control,but the dependence on raw materials of quality of the products is strong.

其中氰化亚金具有极大的现实意义：一方面，钠、钾、钙的金氰络盐是易溶化合物，它们可以通过在空气中氧的参与下溶于相应的氰化物中而制得，这是氰化法从矿石中提金的基础；另一方面，金的氰化物在高科技领域中的应用日益广泛。

This paper puts forward the Theory of Oxidant supplying Oxygen which better explains the leaching mechanism. This theory absorbs and denies the five theories brought up about gold leaching mechanism with cyanide, analyses and caculates from them odynamics and kinetics respectively. These give reliable theorial basis for further catching the mechanism and essence of cyaniding and non cyaniding ways.

论文对氰化浸金机理的五种理论进行了论证和分析，从热力学和动力学上分别进行了理论分析和计算，提出了比较合理的解释浸金机理的供氧体氧化剂理论，为深入理解氰化法和非氰化法提金的机理和本质，提供了理论基础。

Various testings were conducted on the ore and the conclusions are as follows:Gold leaching rate is lower than 17% by all sliming cynidation;Gold leaching effect is poor by floatation and roasting cynidation;Bio preoxidizing cynidation and alkali soaking cynidation get the best results,the highest gold leading rate is up to 92 4%,and they are the effective meth...

通过各种选矿试验，该矿矿石用全泥氰化法金浸出率低于17％，浮选、焙烧氰化法浸出效果也不好，而用细菌预氧化、碱浸预氧化氰化法效果较好，金浸出率最高可达92.4％，是处理该类矿石较有效的选矿方法。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
