Environmental impact of iron ore mining
In most cases, ores are mined and then subjected to various mechanical and chemical metallurgical processes in order to extract the metals and convert them to metallic (chemically uncombined) form. Metal recovery from ore entails three types of operations. - The metal separation (ore dressing) - Initial chemical treatment
