One of the most important methods in the beneficiation of sulfide ores is flotation. Flotation experiments on a laboratory scale are mainly carried out through batch flotation and microflotation tests. In this study, comparative flotation experiments of pyrite minerals were conducted under the same conditions using the two methods mentioned above. A series of experiments were carried out with different pH values and collector dosages selected as flotation parameters. The highest flotation recovery was obtained at a pH of 7.5 with the use of PAX. Furthermore, within the conditions studied, a correlation of 94% was found between the two flotation techniques when using PAX, while it was 98% in the use of PEX. In this study. It was shown that the microflotation method can be used to estimate the efficiency values that can be obtained with batch flotation experiments.

MİKROFLOTASYON VE FLOTASYON HÜCRESİ İLE YAPILAN TESTLERİN FLOTASYON VERİMLİLİKLERİNİN KARŞILAŞTIRMALI ANALİZİ

Öz

Sülfürlü cevherlerin zenginleştirilmesinde kullanılan en önemli yöntemlerden birisi flotasyondur. Laboratuvar ölçeğinde flotasyon deneyleri yoğun olarak kesikli flotasyon ve mikroflotasyon testleri aracılığı ile gerçekleştirilmektedir. Bu çalışmada, bahsedilen iki yöntem kullanılarak, pirit mineralinin aynı şartlar altında karşılaştırılmalı flotasyon deneyleri gerçekleştirilmiştir. Flotasyon parametreleri olarak farklı pH ve toplayıcı dozajları seçilerek bir dizi deney yapılmıştır. En yüksek flotasyon verimleri pH 7,5 da PAX kullanımında elde edilmiştir. Ayrıca çalışılan koşullar aralığında, iki flotasyon tekniği arasında PAX kullanımında %94, PEX kullanımda ise %98 korelasyon olduğu tespit edilmiştir. Bu çalışmada kesikli flotasyon testleri ile elde edilebilecek verim değerlerinin tahmini için mikroflotasyon yönteminin kullanabileceği gösterilmiştir
