Abstract

Bu çalışmada, Yozgat/Sorgun linyit kömürünün flotasyon yöntemi ile zenginleştirilmesinde etkili olan bazı temel proses parametrelerinin kül içeriği ve yanabilir verim üzerine etkileri araştırılmıştır. Deneysel çalışmalarda; pülp pH’sı (2, 3, 5, 7, 9 ve 12), katı oranı (%10, %15 ve %20), flotasyon süresi (2, 4, 5 ve 6 dakika) ve kömür tane boyutu (-75 µm, -125 µm, -250 µm ve -500 µm) parametreleri optimize edilmiştir. Deney sonuçlarına göre optimum flotasyon koşulları; pülp pH’sı 7, katı oranı %15, flotasyon süresi 5 dakika ve kömür tane boyutu -500 µm olarak belirlenmiştir. Bu koşullarda kömürün kül içeriği %38.7’den %34.8’e düşürülmüş ve yanabilir verim %63.9 olarak elde edilmiştir. Ayrıca, linyit kömürünün kalorifik değeri 3563 kcal/kg’dan 4144 kcal/kg’a yükseltilmiştir. Elde edilen sonuçlar, düşük kaliteli linyit kömürünün flotasyon yöntemi ile zenginleştirilmesinin mümkün olduğunu ve proses parametrelerinin seçiminin ürün kalitesi ve verim üzerinde önemli bir etkiye sahip olduğunu göstermektedir.

Abstract

In this study, the effects of some basic process parameters on ash content and combustible recovery in the beneficiation of Yozgat/Sorgun lignite coal by flotation method were investigated. In the experimental studies, the parameters of pulp pH (2, 3, 5, 7, 9 and 12), solid ratio (10%, 15% and 20%), flotation time (2, 4, 5 and 6 minutes) and coal particle size (-75 µm, -125 µm, -250 µm and -500 µm) were optimized. According to the experimental results, the optimum flotation conditions were determined as pulp pH 7, 15% solid ratio, 5 minutes flotation time and coal particle size of -500 µm. Under these conditions, the ash content of the coal was reduced from 38.7% to 34.8% and the combustible recovery was obtained as 63.9%. In addition, the calorific value of the lignite coal was increased from 3563 kcal/kg to 4144 kcal/kg. The results obtained show that it is possible to enrich low quality lignite coal by flotation and that the choice of process parameters has a significant effect on product quality and recovery.
