WebBiobeneficiation of Iron Ores . World demand for iron ores to meet the ever-increasing requirements of iron and steel industries has made it imperative to utilize all available resources including lean grade ores, mined wastes, processed tailings, and blue dust fines accumulated at mine sites. Most of such resources exist as finer particles ... 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. Bioleaching is more cost-effective than smelting processes.
