Webbeneficiation: [noun] the treatment of raw material (such as iron ore) to improve physical or chemical properties especially in preparation for smelting. 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. http://article.sapub.org/10.5923.j.mining.20120102.01.html shush machine for babies
