Abstract

Bu çalışmada, sülfürlü bakır-molibden cevherinden (%0,458 Cu, %0,042 Mo) elde edilen toplu Cu-Mo konsantresinin (%12,02 Cu, %1,37 Mo) biyoflotasyon yöntemiyle zenginleştirme olanakları araştırılmıştır. Pülp pH’sı, bakteri türü ve bakteriyel kıvamlama süresi değişkenlerinin Cu-Mo konsantresinden seçimli olarak kalkopirit ve molibdenit konsantrelerin kazanımına etkileri incelenmiştir. Toplu konsantreden kalkopiritin bastırılması amacıyla asidofilik Acidithiobacillus ferrooxidans ve Acidithiobacillus thiooxidans türü bakteriler kullanılmıştır. Düşük pH’da (2-2.5) yapılan biyoflotasyon deneylerinde seçimliliğin olmadığı görülmüştür. At. ferrooxidans ile pH 5-6 aralığında yapılan biyoflotasyon sonucunda, %3,2 Mo içeren %88,2 verimle bir molibdenit konsantresi ve %15,65 Cu içeren %80,6 verimle bir kalkopirit konsantresi üretilmiştir. At. ferrooxidans türü bakterinin, At. thiooxidans’a göre kalkopiriti daha etkin şekilde bastırdığı belirlenmiştir.

嗜酸性细菌对硫病毒molide浓度的选择性生物处理

此时，研究了从硫病毒性钼中获得的总Cu-Mo浓度（12,02Cu，%1,37Mo），以通过生物法削弱总Cu-Mo的浓度（%0458Cu，%0042Mo）。纸浆pH值已被分析为选择性从细菌和细菌降解期的Cu-Mo浓度变化，并显示了钙和钼浓度的影响。氧化亚铁酸硫杆菌和氧化硫酸硫杆菌已被用于抑制钙骨炎的总浓度。在低pH（2-2.5）的生物运动试验中，别无选择。作为在pH 5-6和马力氧化铁之间进行的生物活化的结果，在3.2MB中产生88.2%的钼浓缩物，在15.65Cu中产生80.6%的钙浓缩物。马的铁氧化物类型是由马的氧化硫决定的，氧化硫能更有效地推动钾。

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.
