“…They in particular determine the results of deashing and desulphurization of coal. In fact, the obtained results confirmed known data [12,13] about the decisive influence of the above-mentioned technological factors on the process. The second part of research examines the influence of aqueous phase on the progress and results of the process: lake water and seawater (the water of the Mediterranean Sea, Aegean Sea, and the water of the Black Sea).…”

“…We shall note that the range of original pulp densities in the conducted experiments, ρ ws =50-600 g/cm 3 , is considerably wider than that in articles [9,[11][12][13][14]. At the same time, lower limits of ρ ws are close (we have 5 %, in [9] -7.5 %, in [11] -11.1 %).…”

“…Study [12] established the following factors that influence the process of oil aggregation of stone coal: type of oil, the content of coal in the pulp, oil content, agglomeration duration, dimensionality of original coal, agglomeration, pH of the pulp, rate of agitation. Authors registered not only ash content reduction, but also desulphurisation of the original coal.…”

“…However, further increase in agitation rate to 2000 rpm, resulted in a decrease in ash reduction adversely affecting the selectivity. This may be due to the trap of mineral particles into the agglomerates as a consequence of excessive turbulence induced in the system [8,9]. In addition, increase in 2500 rpm may be due to break of aggregates to contact an increase with the aggregates and stirring blade, because the increment of agitation rate may also increase the collision chances of granulated aggregates with each other.…”

Nowadays, coal production increases continuously due to an increase in mechanization in coal mining and demand in its related fields of application worldwide. Coal production in China is especially an increasing trend and a large amount of waste fine coal is produced. Waste fine coals usually contain large amounts of ash and inorganic sulfur due to non-selective coal mining of the coal. Therefore, waste fine coals are available as a resource and cause spontaneous combustion leading in turn to air pollution because of their coal contents and small particle sizes which increases the surface area liable to be wet and oxidized, and the disposal site of waste fine coals cause land occupation, soil pollution and water contamination.In this study, a vegetable oil agglomeration process was performed for coal recovery from Chongqing Nantong waste fine coals in China. The oil agglomeration process has been used to mineral oil of exhaustible resource. Therefore, in this study, several kinds of vegetable oils are selected as oil agglutinative agents because the vegetable oils which are renewable, available and less-pollutant energy resources. The effects of the parameters including particle sizes, agitation conditions, chemical structure and viscosity of vegetable oils were investigated based on the combustible matter recovery, ash reduction and efficiency index. It was concluded that particle sizes of waste fine coal, agitation rate and agitation time will influence on the recovery efficiency of combustible matter from its original waste coal by the colza oil agglomeration. Furthermore, a wide range of vegetable oil alteration grades including prepared waste vegetable oil samples and therefore, of oil properties, such as chemical structural changes and unsaturated carbonaceous functional groups by the oxidation processes in the used waste vegetable oils have to be achieved.
