Depending upon the medium used for beneficiation of coal, the various processes are classified as WET or DRY. Those processes using water as medium are WET processes and are known as Washing Processes. The coal beneficiation plants using wet processes are named as Coal washeries.
Coal beneficiation is a generic term that is used to designate the various operations performed on the ROM coal to prepare it for specific end uses, such as feed to a coke oven or a coal-fired boiler or to a coal conversion process …
Medium coking coals cannot be directly used to produce coke without prior treatment, such as beneficiation, or requires blending with a better quality of coal. This category of coal can be further classified into high (VM > 32%), medium (VM 20–32%), and low (VM 15–20%) volatile coals.
Tharisa, the platinum group metals (PGMs) and chrome co-producer, has announced that cold commissioning of its Vulcan ultra-fine chrome recovery and beneficiation plant has commenced. The timetable to completion of the new $55 million plant remains firmly on track with initial saleable production due before year end, it says.
Mineral processing, mineral beneficiation, or upgradation involves handling three primary types of ROM material, which have been blasted, fragmented, and brought out from an in situ position. These materials can be used directly or by simple or complex processing and even by applying extractive metallurgy like hydrometallurgical or pyrometallurgical …
