Heap Leaching Oxide and Sulfide Copper Ores

The acid consumptions curves for the oxide copper ore (number 3) with a high iron oxidetactile gangue were somewhat different than those of oxide copperporphery gangue ore number 1. In tests 9 through 14 the incremental acid curves were generally low at the start, fairly high after 3 to 4 days of leaching, and very high thereafter.
