8 Types of Gold Ore

Jul 12, 2021The amount of iron oxide copper gold ore is about 10 million to 4 billion tons. IOCG ore contains copper with a grade of 0.2% to 5% and gold with a content of 0.1 to 1.41 grams per ton. Iron oxide copper gold ore tends to be conical on the edge of granite, or appears as long banded breccia or massive iron oxide ore in faults or shears.
