Shitouding ore section of Caojiawa gold deposit is located at the footwall of Zhaoping fault belt in the northwestern Jiaodong gold concentration area.Field exploration and drilling found that this section has strong pyritic sericite alteration,which is the main symbol of ore-forming surrounding rocks in this area.It has good metallogenic prospects,but no breakthrough has been made in prospecting work.After carrying out 1∶10 000 soil geochemical survey,we used correlation analysis and R-type cluster analysis and other methods to study the distribution characteristics of element anomalies in the working area from the perspective of geostatistics.With previous geological data and current exploration situation,the anomalies were delineated and four target areas of H1~H4 were divided,all of which had good metallogenic prospects.Regarding the geochemical prediction and geophysical results,it is found that the variation coefficient of gold in H4 and H2 target areas was 0.976,and the average anomaly value was 4.9×10-9~5.3×10-9,which was consistent with the geophysical results.It is speculated that the anomaly is caused by ore.

欧洲科学家提出新型黄金提取工艺
芬兰阿尔托大学的研究人员在Chemical Engineering期刊发表论文“Electro-hydrometallurgical chloride process for selective gold recovery from refractory telluride gold ores: A mini-pilot study”,描述了一种新的、可扩大规模的、无毒的氰化物替代品,以用于从矿石中提取黄金。新工艺是基于氯化物浸出和回收黄金。
该研究的第一作者Ivan Korolev在一份媒体声明中表示,“通过我们的工艺,能够使用氯化物回收的黄金量高达84%。相比之下,在我们的对照实验中,对同一矿石使用标准氰化物工艺的产率仅为64%。”
这种新方法被称为电沉积—氧化还原置换(EDRR),结合了电解和络合。其中,电解使用电流来还原浸提液中存在的金或其他金属,络合将其他金属的颗粒添加到溶液中与金反应。Korolev及其同事用铜来测试这种方法,施加短脉冲电流,在电极上形成金属薄层并引发反应,从而促使金逐层置换铜。
实验室工作是与芬兰采矿技术巨头美卓奥图泰合作进行的。Korolev表示,“与美卓奥图泰的合作使我们能够以一种更接近现实情况的方式开发这种方法。我们最初的回收率约为9%,但随后增长到了25%,并很快达到了70%,有时甚至接近95%。”
据称,这是首次在大规模环境下进行这样的实验。鉴于其积极的结果,预计会令矿业企业对这项技术感兴趣,并愿意在现场进行测试。Korolev表示,“过去的提取方法总是会留下一些有价金属。现在,随着对金属需求的不断增长,即使是这些少量的金属也很重要。我认为仍然可以用我们的电沉积—氧化还原置换技术提高产量。也许达不到100%,但我相信可以达到90%或更多。”
