Abstract

Flotasyon işlemlerinde tane boyutu ve tane morfolojisi gibi tanelerin fiziksel özellikleri, hem tane-tane hem de tane-kabarcık etkileşimlerinde önemli bir rol oynar ve bu da onları flotasyon işlemlerinin değerlendirilmesinde çok önemli kılmaktadır. Bu çalışmada, farklı sürelerde pürüzlendirilen galen tanelerinin pürüzlülük süresine bağlı olarak elde edilen morfolojik özelliklerinin flotasyon verimi ve topaklanma özelliklerine etkisi araştırılmıştır. Deneysel çalışmaların sonuçlarına göre artan pürüzlülük değerlerinde tanelerin flotasyon ve topaklanma özelliklerinin önemli oranda arttığı belirlenmiştir. Sonuç olarak tanelerin tercihli üretimi ile flotasyonun daha düşük kollektör konsantrasyonlarına ötelenerek daha verimli hale getirilebileceği belirlenmiştir.

Effect of Particle Roughness on Flotation and Aggregation of Galena Mineral

Abstract

Physical properties of particles such as particle size and particle morphology plays an important role on both particle-particle and particle-bubble interactions which makes them very important on evaluation of flotation processes. In this study, the contribution of roughness of galena particles produced as a function of abrasion time was investigated on their flotation recovery and aggregation characteristics. According to the results of experimental studies, it was found that the flotation and aggregation characteristics increased in proportion to their roughness value. As a result, it was determined that with the preferential production of particles, flotation can be made more efficient by shifting to lower collector concentrations.
