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.

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.
