“…This paper is concerned with both the dynamics and steadystate distribution of a system of particles composed of different densities and sizes in a liquid-fluidized bed. This kind of system occurs in mineral processing (Rubiera et al, 1997;Galvin, 2003), where the particles cover a wide range of sizes and densities. Liquid fluidization has also been used in food technology, biochemical processing, and hydrometallurgy (Di Felice, 1995).…”

“…So, determination of washability characteristics of lignites and understanding the physical separation requirements beforehand should include the consideration of particle size. Although fine coal cleaning is off great importance by many researchers [18][19][20][21][22][23], still the washability characterization of lignites has significance in terms of ash and sulfur reduction which are crucial in terms of the processes of further utilization. In addition to the abovementioned, Hacifazlioglu and Toroglu [24] have investigated the optimum design and operating parameters of slime coal cleaning in a pilot scale Jameson cell.…”

In the scope of this study, in order to determine the floatability characteristics of lignites, 5 samples were collected from various lignite reserves of Turkey namely Dursunbey, Çayırhan, Ilgın, Ermenek, and Gürmin-Merzifon. Collected samples were analyzed in terms of float and sink analysis. As regards to float and sink analysis, the original samples were floated and sinked in 2 different ZnCl2 solutions of densities 1.40 and 1.60 g cm-3. Proximate analysis of each original sample for the corresponding lignite was carried out in the beginning of this study. In terms of proximate analysis performed, Dursunbey lignite sample has the lowest ash content of 24.86 % while Gürmin Merzifon lignite sample has the highest ash content of 45.02 %, respectively. Accordingly, 5 float and sink analysis graphic obtained and they would help one to understand and easily figure out the optimum medium density for cleaning.

“…It consists of a central perforated cone containing horizontal ribs along the inside wall. As a result, the mineral grains remain mobile, allowing more heavy particles to penetrate the fluidized bed [17]. As the magnitude of the applied centrifugal force increases, the size of the particles to be recovered becomes smaller [18,19].…”

The quality of coals from, Erzurum varies widely. Two coal samples from this area were compared. The first has a composition of 19% ash, 5700 kcal, and 3% sulfur while the other has 49.20% ash, 3000 kcal, and 1.6% sulfur composition. It is understood that the first coal sample is a high-quality coal. Although the ash content of the second coal sample is determined to be high and the calorie value is low, the low sulfur content is advantageous for the environment. This study aimed at increasing the quality of coal samples by carrying out experiments for reducing the ratio of ash and sulfur with Knelson’s enrichment processes. Chemical analysis, sieve analysis experiments, %ash, %moisture, and %calorie values of each fraction are determined from two different C1 and C2 coal samples taken from the Balkaya village belonging to Şenkaya, Erzurum. Then, %ash, %yield, and %sulfur analyzes were carried out on the coal samples using the Knelson gravity separator enrichment method, and the results were evaluated for coal samples.
