In the mining industry or extractive metallurgy, beneficiation is any process that improves (benefits) the economic value of the ore by removing the gangue minerals, which results in a higher grade product (ore concentrate) and a waste stream (tailings). There are many different types of beneficiation, with each step furthering the concentration of the original ore.
WebSome advantages of bioleaching include: Bioleaching can stabilise sulphate toxins from the mine without causing harm to the environment. Poisonous sulfur dioxide emissions harm the environment and can cause health problems for miners, and bioleaching avoids this process entirely.
