一、前言 在试验室试验研究的基础上(试验结果已在本刊一九八一年第四期“含金黄铁矿烧渣提金的研究”一文中发表),一九八二年在河北省迁西县化工厂进行了日处理25吨规模的含金烧渣氰化提金的工业试验。首次在国内把金精矿氰化尾矿烧渣的氰化提金工艺应用于工业生产,并获得了较好的技术经济效果,达到了变废为宝的目的,为我国在含金烧渣中回收黄金开辟了一个新途径。于一九八二年十二月冶金部黄金局对这一科技成果进行了技术鉴定。
I. Preface On the basis of the laboratory test and research (the test result has been published in the article entitled “Study on Gold Extraction from Gold-bearing Pyrite Cinders”, Issue 4, 1981), in 1982, Provincial Qianxi County Chemical Plant for the day processing 25 tons of gold-containing gold slag gold cyanide industrial test. For the first time in the country gold concentrate cyanide tailings cyanide gold extraction process used in industrial production, and obtained a good technical and economic results, reaching the purpose of turning waste into treasure for our gold-bearing slag In the recovery of gold opened up a new way. In December 1982, the Ministry of Metallurgical Administration conducted a technical appraisal of this scientific achievement.
