Rather than meaning that the maximum potential of a resource has been exploited, beneficiation refers to business practices which benefit the communities where products are mined, harvested, and otherwise taken. Historically, major companies have tended to enter small communities, take resources, and then leave, with no benefit to the populace.

Thermal beneficiation also eliminates ammonia issues and can improve fineness and uniformity. Successful thermal beneficiation technologies have been commercially deployed since 1999 (Keppeler, 2001). This technology produces more than a million tons of marketable fly ash per year in the eastern United States.

As shown in Table 3, the beneficiation degree in case D (965) is higher than in case C (252). Although case D has a higher beneficiation degree, the total energy consumption and GHG emissions of producing one tonne FeMo are smaller than for case C, which are 29.1 GJ/t FeMo and 3.16 tCO 2 -eq/t FeMo, respectively.

Beneficiation is followed by processing activities such as smelting and refining. The beneficiation process begins with milling, which is followed by flotation for further beneficiation. At the first stage, extracted ores undergo the milling operation to produce uniformly sized particles for crushing, grinding, wet or dry concentration.
