Mineral beneficiation during construction/operation may have impact on groundwater quantity and quality. Pollutants from the tailings are likely to enter the groundwater. This is likely to increase concentration of leachable pollutants from waste and ore concentrate, which may migrate to the neighboring groundwater.

Beneficiation (Metallurgy)
Microbially induced mineral beneficiation involves three strategies, namely, selective bioleaching of the undesirable mineral from an ore or concentrate, selective flotation of the mineral, or selective dispersion/flocculation. Such microbially induced beneficiation will find applications in a number of areas such as: Desulfurization of coals ...
Mineral Beneficiation : A Concise Basic Course
Mineral Beneficiation. : Mineral Beneficiation or ore dressing of run-of-mine ore is an upgrading process to achieve uniform quality, size and maximum tenor ore through the removal of less valuable material. Beneficiation benefits the costs of freight, handling, and extraction (smelting) reduce, and the loss of metal through slag.
22.4: Beneficiation
Page ID. Beneficiation is any process which removes the gangue minerals from ore to produce a higher grade product, and a waste stream. Beneficiation may involve physical or chemical processes. Often, as in the case of panning for gold, the desired ore or metal is denser than the gangue. The latter can be suspended in a stream of water and ...

Mineral Processing. Swapan Kumar Haldar, in Mineral Exploration (Second Edition), 2018. 13.2.4.3 In-Stream Analyzer and Process Control. Mineral beneficiation, particularly base and noble metals, is sensitive to optimum use of reagents, recovery of metals, and clean concentrate.High fluctuation of feed grade at flotation cells yields loss of metals to tailing.
Mineral Beneficiation | Hazen Research
Mineral beneficiation is the process of concentration, and was first described in Agricola's famous treatise, De Re Metallica, published in 1556. The earliest ores to be discovered and processed were of such high grade that they did not require beneficiation, and they satisfied mankind's needs for nearly 3,000 years. By the end of the ...
