Mineral processing or mineral beneficiation or upgradation involves handling of three primary types of ROM ore material which has been blasted, fragmented and brought out from in situ position. These materials can be used directly or by simple or complex processing and even applying extractive metallurgy like hydrometallurgical or pyrometallurgical methods.

2018-6-1 Minerals bearing REE are available in mining reserves such as in mineral rocks mined from dry lands or placer deposit dug from watery reserves (Jordens et al., 2013, Rezaee Ebrahim Saraee et al., 2009, Sultan and Shazili, 2009). However, the concentration of REE in most of rock forming mineral is not economically efficient for commercial refining.
