Ultrasonik işlemin düşük dereceli kömürün kolon flotasyonu üzerine etkisi

Abstract

Bu çalışmada, ultrasonik işlemin düşük dereceli linyit kömürünün kolon flotasyonu üzerindeki etkisi araştırılmıştır. Ayrıca ultrasonun gücü ve tedavi süresi flotasyon süreçini önemli derecede etkilemiş ve en iyi değerler 60 Watt ultrason gücünde ve 3 dakikalık muamele süresinde elde edilmiştir. Ultrasonik işlemin güç değerlerinin ve muamele süresinin daha fazla artması flotasyon başarısını olumsuz yönde etkilemiştir. Ayrıca, optimum kül içeriği ve yanabilir verim değerleri 1000 g/ton toplayıcı ve 2000 g/ton köpürtücü konsantrasyon değerlerinde elde edilmiştir. Ultrasonik işlem flotasyon reaktiflerinin aktivitesinin artırarak flotasyon sürecini iyileştirmiştir. Ayrıca ultrasonla yapılan deneylerde temas açısı değerlerinin aynı deneysel koşullar altında klasik yapılan deneylere göre daha yüksek olduğu tespit edilmiştir. Sonuç olarak,% 28,01 kül içeriğine sahip kömür, ultrasonik işlem kullanılarak% 13,94 kül içeriği ve % 76,25 verim ile zenginleştirilmiştir.
