摘要

长石通常与钛和铁矿物结合在一起。长石应通过通常的磁选或/和高品位浮选与其他矿物分离。然而,由于性质相似,长石很难通过浮选从脉石矿物中分离出来。在本研究中,通过云母浮选研究了铁的降解性,并使用中央复合设计(CCD)对结果进行了规划和分析。在研究过程中,模拟了固体比、pH、收集器数量和气流对所获得的清洁长石的铁含量和产率的影响。然后,进行了最佳条件的估计和验证试验。通过云母浮选,铁含量降低到0.14%。然而,这一减少数额被认为是不够的。最后,铁含量降低到0.05%。考虑到优质长石的最大铁含量为0.1%,可以说,在没有磁选等不同工艺的情况下,两阶段浮选是成功的。

Modelling of the flotation process by Central Composite Design for obtaining superior grade feldspar
Feldspar is usually found in conjunction with titanium and iron minerals. Feldspar should be separated from other minerals by generally magnetic separation or/and flotation with high grade. However, due to the similarities in the properties, feldspars are difficult to separate from gangue minerals by flotation. In this study, the degradability of iron was investigated by mica flotation, and Central Composite Design (CCD) was used to plan and analyze the results. During the study, the effect of solid ratio, pH, collector amount and airflow on the iron content and the yield of the obtained clean feldspar were modelled. Then, estimation of the optimum conditions and verification tests were performed. The iron content was reduced to 0.14% by mica flotation. However, this reduction amount was found to be insufficient. Finally, iron content was reduced to 0.05%. Considering that the maximum iron content of the superior grade feldspar is 0.1%, it can be said that two stage flotation is successful without different processes such as magnetic separation.

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.
