sodium gold cyanide

Technology of non-cyanide Cu-Zn-Sn-Ni tetrabasic alloy imitative gold electroplating on FRP was studied using potassium pyrophosphate as main complexing agent, potassium sodium tartrate as auxiliary complexing agent and laboratory-synthesized copper pyrophosphate and zinc pyrophosphate as main salts.

以焦磷酸钾为主络合剂、酒石酸钾钠为辅助络合剂，自制焦磷酸铜、焦磷酸锌为主盐进行了玻璃钢无氰Cu-Zn-Sn-Ni四元合金电镀工艺研究。

The free cyanogen determinator is used to make density analysis of free sodium cyanide in the cyanide leaching solution of gold ore.

游离氰测定仪用于金矿氰化液中的游离氰化钠浓度分析。

In the first 5 hours of leaching, the impure mineral consumed most of free sodium cyanide of the liquor, in that case, the rate of gold leaching is low.

在搅拌浸出最初的5小时内，杂质矿物消耗了溶液中大部分的游离氰化钠，金的浸出率偏低。
