国内金精矿氰化提金技术现状

Present Situation of Gold Cyaniding Withdraw Gold Technology in Domestic

金精矿氰化提金技术是我国黄金工业主要直接产金的手段 ,它包括简单含金银矿物的精矿二浸二洗工艺 ,还包括一些富含铜、铅等金属需要添加某种助浸剂的氰化技术 ,小秦岭一带矿山生产金银铜铅锌与硫多金属精矿 ,即需要焙烧后酸浸除去硫铜铅再氰化 ,而湖南湘西金矿所产金锑钨精矿也需焙烧后处理 ,若含砷金精矿需要经过焙烧、热压及细菌氧化后再氰化提金 ,并已逐步进行工业化生产。总之 ,随着社会进步与科研工作不断深入发展 ,我国金精矿氰化提金工艺技术日臻完善 ,并将会在今后工业生产中作出更大贡献。

Gold concentrate cyaniding withdraw gold technology is mainly and directly produce gold in our country gold industry.It simple including two soak and two washing technics of concentrate rich in gold and silver mineral and cyaniding technology of some metal rich in copper(Cu)and lead(pb) need to add a certain infusion.The mine located in small qinling range produce metal concentrate rich in much gold?silver?copper?lead?zinc and sulpher,which need roast to get rid of sulpher?copper and lead via sour infusion,then can be cyanided.Howver,Hunan Xiangxi Gold Mine produce concentrate rich in gold ?stibiurn(sb) and wolfram(w) also need roast and gold concentrate rich in arsenic(As) need roast ?hot pressure and bacterial oxidation,then withdraw gold via cyanided,approaching into industrialization production.In a word,our country's gold concentrate cyaniding withdraw gold technology be getting better and better with social advancement and deeply develop work,and will make greater controbution in the industrial production in the future.
