Özet
Bu çalışmada, Eskişehir ili sınırları içerisinde bulunan ve ülkemiz açısından ekonomik değeri oldukça
yüksek olan bastnasit cevherinde bulunan Barit (BaSO4) mineralinin flotasyon tekniği ile seçici olarak
cevherden ayırımı ve yüksek saflıkta barit elde edilmesi amaçlanmıştır. İlgili bölgeden tekniğe uygun
olarak alınan cevher numunesi kırıtıcı-öğütücü yardımı ile öğütülmüş ve uygun tanecik boyutuna
getirilmiştir. Uygun tanecik boyutundaki cevher numunesine eleme işlemi uygulanmış ve bu sayede uygun
tanecik boyutlu ve homojenize edilmiş numune elde edilmiştir. Homojenize edilmiş numune içerisinde
bulunan mineral analizi için uygun çözünürleştirilme işlemi yapıldıktan sonra analizler yapılmış, cevher
bünyesinde bulunan, bastnasit, barit ve fluorit gibi minerallerin numune içerisindeki miktarları tespit
edilmiştir. Ön flotasyon işlemleri ile baritin flotasyon verimleri incelenmiş ancak istenilen düzeyde
zenginleştirilme yapılamamıştır. Flotasyon veriminin düşük olmasının cevherin minerolojik yapısından
kaynaklandığı düşünülmüş ve cevherin kristal yapısını değiştirmek amacıyla flotasyon işleminden önce
sülfürleme prosesi gerçekleştirilmiştir. Sülfürleme prosesinden sona gerçekleştirilen flotasyon
çalışmalarında baritin flotasyon veriminde ciddi oranda artış olduğu yapılan deneyler sonucunda
görülmüştür. Tespit edilen optimum flotasyon koşullarında yapılan deneylerde cevher bünyesinde yer alan
baritin % 92.04 flotasyon verimi ile cevherdeki tenörürünün % 31,13’den % 91.14’e yükseldiği tespit
edilmiştir.
In this study, it is aimed to selectively separate the barite (BaSO4) mineral found in bastnasite ore, which is located within the borders of Eskişehir province of our country and has a very important place in terms of economic return to our country, from the ore by flotation technique and to obtain high purity barite. The ore sample taken from the relevant region in accordance with the technique was ground with the help of a crusher-grinder and brought to the appropriate particle size. Sieve process was applied to the ore sample, which was brought to the appropriate particle size, and by this means, the appropriate particle size and homogenized sample was obtained. After the appropriate solubilization process for the mineral analysis in the homogenized sample, analyzes were made and the amounts of minerals such as bastnasite, barite and fluorite in the sample were determined. Pre-flotation processes and barite flotation yields were investigated, but the desired level of enrichment could not be achieved. It was thought that the low retention efficiency of the flotation efficiency was due to the mineralogical structure of the ore and it was subjected to sulphidation before flotation in order to change the crystal structure of the ore. As a result of the experiments, it was observed that there is a significant increase in the flotation efficiency of barite in the flotation processes performed after the sulfuration process. In the experiments carried out under the determined optimum flotation conditions, it was determined that the barite contained in the ore increased from 31.13% to 91.14% with a flotation efficiency of 92.04%.
