INVESTIGATION OF THE ENTRAINMENT OF FINE SIZED CALCITE AND CHROMITE PARTICLES BY A FLOTATION COLUMN WITH NEGATIVE BIAS REGIME
Öz: Negatively Biased Flotation Column (NBFC) is a tool, which is developed for the flotation of coarse-sized ores. Unlike the conventional flotation column, in this column, there is no froth zone and wash-water is usually not used. Therefore, hydrodynamically entrainment of fine-sized particles into the concentrate is possible, and this may result in a decrease in the grade or yield of the concentrate. In this study, operating parameters that can affect the entrainment of fine-sized particles were investigated. Calcite with a grade of 99.4% (CaCO3) and chromite concentrates with a grade of 54.8% (Cr2O3) were used in the experiments. Parameters such as superficial water flowrate, particle size, air flow rate, frother dosage and particle density were used in the experiments. As a result of the experiments, it was determined that the amount of entrainment increased as the particle size and density decreased, and decreased with increasing superficial water flowrate, air flow rate and frother dosage.
Anahtar Kelime: NEGATİF BİAS REJİMİNE SAHİP BİR FLOTASYON KOLONU İLE İNCE BOYUTLU KALSİT VE KROMİT TANELERİNİN SÜRÜKLENMESİNİN ARAŞTIRILMASI
Öz: Negatif Biaslı Flotasyon Kolonu (NBFK), iri boyutlu cevherlerin flotasyonu için geliştirilmiş bir araçtır. Klasik flotasyon kolonundan farklı olarak bu kolonda köpük bölgesi yoktur ve genellikle yıkama suyu kullanılmaz. Bu nedenle, ince boyutlu parçacıkların konsantreye hidrodinamik olarak sürüklenmesi mümkündür ve bu, konsantrenin tenöründe veya veriminde bir düşüşe neden olabilir. Bu çalışmada, ince boyutlu taneciklerin sürüklenmesini etkileyebilecek çalışma parametreleri araştırılmıştır. Deneylerde %99.4 (CaCO3) tenörlü kalsit ve %54,8 (Cr2O3) tenörlü kromit konsantreleri kullanılmıştır. Deneylerde yüzeysel su akış hızı, tanecik boyutu, hava akış hızı, köpürtücü dozajı ve tanecik yoğunluğu gibi parametreler kullanılmıştır. Deneyler sonucunda, tanecik boyutu ve yoğunluğu azaldıkça sürüklenme miktarının arttığı, artan yüzeysel su akış hızı, hava akış hızı ve köpürtücü dozajı ile azaldığı tespit edilmiştir.
