    and refining. Those savings result from the omission of energy-intensive ore grinding and flotation. Limited resources of oxidized copper ores, the long leaching time of chalcopyrite, and an inability to recover gold inhibit growth of this method. In the treatment of copper concen-trates, hydrometallurgical leaching methods have long been studied

    Copper grinding process. This is the process of separating precious minerals from waste rock. At Britannia the copper ore contained just over 1% copper (though in the early years it was around 8%). The remaining 99% was mostly waste rock, called ‘tailings’. In the rock, chemical and physical bonds hold the valuable minerals to the waste rock
