Kinetic Analysis of The Jameson Flotation Cell's Performance in Ultra-Clean Fine Coal Beneficiation

Öz

This study evaluates and optimizes the Jameson flotation cell's performance in the ultra-clean bituminous coal's beneficiation. The experimental design considered three key parameters: frother dosage (15 ppm), bias rate (0,75 cm/s), and a fixed particle size (38 µm). These variables effects on combustible recovery (CR, %) and the flotation rate constant (k), which represents flotation kinetics, were analyzed. Experimental results demonstrate that the Jameson cell achieves high efficiency and rapid flotation kinetics, particularly at fine particle sizes. Additionally, it was observed that the applied bias and frother dosage significantly influence foam stability and bubble-particle interactions, thereby shaping the overall performance.

Ultra Temiz İnce Kömür Zenginleştirme İşleminde Jameson Flotasyon Hücresinin Performansının Kinetik Analizi

Öz

Bu çalışma, ultra temiz bitümlü kömürün zenginleştirilmesinde Jameson flotasyon hücresinin performansını değerlendirmekte ve optimize etmektedir. Deneysel tasarımda üç temel parametre dikkate alınmıştır: köpürtücü dozajı (15 ppm), bias hızı (0,75 cm/s) ve sabit partikül boyutu (38 µm). Bu değişkenlerin yanabilir kısım verimi (CR, %) ve flotasyon kinetiğini temsil eden flotasyon hızı sabiti (k) üzerindeki etkileri analiz edilmiştir. Deneysel sonuçlar, Jameson hücresinin özellikle ince partikül boyutlarında yüksek verimlilik ve hızlı flotasyon kinetiği sağladığını göstermektedir. Ek olarak, uygulanan bias ve köpürtücü dozajının köpük stabilitesini ve kabarcık-partikül etkileşimlerini önemli ölçüde etkilediği ve böylece genel performansı şekillendirdiği gözlemlenmiştir.
