Tailings Dams Briefing Transcript | BHP

The amount of tailings that remain is controlled by what grade the ore is, meaning the percentage of valuable minerals in the ore. For example, if the grade of an ore is 1 percent copper, 99 percent of the total ore would be deposited as tailings. Iron ores generally have higher grades than sulphide or gold ores, often going over 50 per cent or ...
