Us6569391b1 Heap Leaching Copper Ore Using Sodium

The heap leaching of copper bearing ores is improved by using sodium nitrate as an oxidizing chemical reactive in a sulphuric acid leaching solution. In particular, the ore is crushed to 6 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.
