May 18, 2017  Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of high-grade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes, a fine granulometry is produced, and thus iron agglomeration ...

The ore concentration is defined as the chemical process of eliminating impurities like sand, rocks, silt, grit etc. from the ore to extract the metals. In simple words, the concentration of ore is the method of separating ore from the gangue, as the gangue or matrix particles are

Agglomeration - an overview ScienceDirect Topics

Agglomeration helps to maintain quality standards of recycled plastics such as bulk density, particle size, ash content, chloride loading or residual moisture. A frequent prerequisite for further processing is the conversion of mixed plastics into a semi-finished product. This conversion can be achieved by agglomeration, e.g. in a circular die (Fig. VI.5.6).

Mineral processing - Wikipedia

Concentration. There are a number of ways to increase the concentration of the wanted minerals: in any particular case, the method chosen will depend on the relative physical and surface chemical properties of the mineral and the gangue. Concentration is defined as the number of moles of a solute in a volume of the solution.
