The heap leaching of copper bearing ores is improved by using sodium nitrate as an oxidiing chemical reactive in a sulphuric acid leaching solution. In particular the ore is crushed to lt6 mm and stored in heaps less than twelve meters high. The heaps are irrigated with a dilute solution consisting essentially of sulphuric acid and sodium nitrate to produce a leach product
