lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. the results, high-quality fine ore powders, are known as fines. magnetite. magnetite is magnetic, and hence easily separated from the gangue minerals and,rare earth elements a review of applications occurrence,jul 01, 2019 even 50 extraction from the ore will be economical due to high price of hree. as the area is well exposed and outcrops have high relief, the cost through opencast mining will be minimum bhushan and somani, 2019. 4.1.2. residual deposits. residual deposits formed from deep weathering of igneous rocks, pegmatites, iron-oxide copper-gold deposits.
a good deal of data is lacking about the processes of ore formation, ranging from how metals are released from source rocks through transport to deposition and post-deposition alteration. modeling of these processes has been limited by significant gaps in thermodynamic and kinetic data on ore and gangue waste minerals, wall-rock minerals, and,copper production amp environmental impact,depending on whether an ore is sulfide or oxide, the process follows one of two routes. beneficiation beneficiation is the concentration of ore through separation into desirable mineral-the part of the ore that is useable and gangue pronounced gang the part of the ore that is commercially worthless.
