Oil Agglomeration
Oil agglomerationResearch into the process of preparation of Ukrainian coal by the oil aggregation method / V. Biletskyi, P. Molchanov, M. Sokur, G. Gayko, V. Savyk, V. Orlovskyy, M. Liakh, T. Yatsyshyn, R. Fursa / Eastern-European Journal of Enterprise Technologies – 2017. – Vol. 3. – № 5 (87) – P. 45–53. – URL: http://journals.uran.ua/eejet/issue/view/6296. is one of the special processes of mineral processing. It is based on differences in surface properties of desired and undesired minerals i.e., carbonaceous coal particles and gangue minerals. It is used for dressing, dehydration of finely dispersed naturally hydrophobic minerals – most often coal, in the first tests – for sulphide ores, in addition, adhesion minerals processing of gold and diamonds. The product of oil agglomeration of coal is carbonaceous agglomerate or granulate Granulation is the process of forming grains or granules from a powdery or solid substance, producing a granular material.

Mineral Processing
In the field of extractive metallurgy, mineral processing, also known as ore dressing, is the process of separating commercially valuable minerals from their ores. History Before the advent of heavy machinery the raw ore was broken up using hammers wielded by hand, a process called "spalling". Before long, mechanical means were found to achieve this. For instance, stamp mills were used in Samarkand as early as 973. They were also in use in medieval Persia. By the 11th century, stamp mills were in widespread use throughout the medieval Islamic world, from Islamic Spain and North Africa in the west to Central Asia in the east. A later example was the Cornish stamps, consisting of a series of iron hammers mounted in a vertical frame, raised by cams on the shaft of a waterwheel and falling onto the ore under gravity. The simplest method of separating ore from gangue consists of picking out the individual crystals of each. This is a very tedious process, particularly when the in ...

Agglomerate
Agglomerate (from the Latin ''agglomerare'' meaning "to form into a ball") is a coarse accumulation of large blocks of volcanic material that contains at least 75% bombs. Volcanic bombs differ from volcanic blocks in that their shape records fluidal surfaces: they may, for example, have ropy, cauliform, scoriaceous, folded, spindle, spatter, ribbon, ragged, or amoeboid shapes. Globular masses of lava may have been shot from the crater at a time when partly molten lava was exposed, and was frequently shattered by sudden outbursts of steam. These bombs were viscous at the moment of ejection and by rotation in the air acquired their shape. They are commonly in diameter, but specimens as large as have been observed. There is less variety in their composition at any one volcanic centre than in the case of the lithic blocks, and their composition indicates the type of magma being erupted. Agglomerates are typically found near volcanic vents and within volcanic conduits, where they m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Granulate
Granulation is the process of forming grains or granules from a powdery or solid substance, producing a granular material. It is applied in several technological processes in the chemical and pharmaceutical industries. Typically, granulation involves agglomeration of fine particles into larger granules, typically of size range between 0.2 and 4.0 mm depending on their subsequent use. Less commonly, it involves shredding or grinding solid material into finer granules or pellets. From powder The granulation process combines one or more powder particles and forms a granule that will allow tableting to be within required limits. It is the process of collecting particles together by creating bonds between them. Bonds are formed by compression or by using a binding agent. Granulation is extensively used in the pharmaceutical industry, for manufacturing of tablets and pellets. This way predictable and repeatable process is possible and granules of consistent quality can be produced ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
