Abstract

Flotation is one of the widely used mineral processing methods where hydrophobic particles are separated from hydrophilic particles using air bubbles. Since some minerals such as talc, graphite, molybdenite, hard coal, and sulphur is naturally hydrophobic, it is possible to float them without collector. The effect of flotation chemicals such as collector and frothers which are very expensive, and the water quality is very important in the flotation method. For this reason, the decrease in the amount of these chemicals for the flotation method or even not to use any of these chemicals may reduce the cost of mineral processing. Dissolved air flotation (DAF) is a clarification process that can be used to remove particles. In addition, when water scarcity and contamination are considered, water circulation and use of bore water which contains a high amount of salt, will be essential for mineral processing plants in the future. In this context, the aim of this study was to investigate the flotation behavior of natural hydrophobic mineral talc in solutions (NaCl and MgCl2) without collector using a lab scale DAF. The flotation results showed that flotation yield of talc increased 14% in the presence of salt ions. Based on the results obtained from this study, it can be concluded the effect of dissolved ions such as Na+ and Mg2+ on talc flotation is ion specific.

浮选是一种广泛使用的矿物加工方法，其中使用气泡将疏水颗粒与亲水颗粒分离。由于滑石、石墨、辉钼矿、硬煤和硫等一些矿物具有天然疏水性，因此可以在没有收集器的情况下使其漂浮。浮选化学物质（如捕收剂和起泡剂）的效果非常昂贵，水质在浮选方法中非常重要。出于这个原因，用于浮选方法的这些化学物质的量的减少或者甚至不使用这些化学物质中的任何一种都可以降低矿物加工的成本。溶解空气浮选（DAF）是一种可用于去除颗粒的澄清过程。此外，考虑到缺水和污染，水循环和使用含盐量高的地下水对未来的选矿厂至关重要。在这种情况下，本研究的目的是使用实验室规模的DAF研究天然疏水矿物滑石在没有捕收剂的溶液（NaCl和MgCl2）中的浮选行为。浮选结果表明，在盐离子存在下，滑石的浮选收率提高了14%。根据本研究的结果，可以得出Na+和Mg2+等溶解离子对滑石浮选的影响是离子特异性的。Orijinal Araştırma/原创研究ÇÖZÜNMÜŞHAVA FLOTASYONU。

期刊介绍： Scientific Mining Journal, which is published i n open access electronic environment and i n printed, is a periodical scientific journal of Union of Chambers of Turkish Engineers and Architects Chamber of Mining Engineers. The name of the journal was "Mining" until June 2016 and it has been changed to "Scientific Mining Journal" since September 2016 because it can be confused with popular journals with similar names and the ISSN number has been updated from 0024-9416 to 2564-7024. Scientific Mining Journal, published four times a year (March-June-September-December), aims to disseminate original scientific studies which are conducted according to the scientific norms and publication ethics at national and international scale, to scientists, mining engineers, the public; and thus to share scientific knowledge with society. The journal is in both Turkish and English. The journal covers theoretical, experimental, and applied research articles, which reflects the findings and results of an original research i n the field of mining engineering; review articles, which assess, evaluates, and interprets the findings of a comprehensive review of sufficient number of scientific articles and summarize them at present information and technology level; technical notes, which may be defined as a short article that describes a novel methodology o r technique; a case studies, which are based on the theoretical o r real professional practice and involves systematic data collection and analysis.
