Re-thinking complex orebodies: Consequences for the

2019-5-20  By 2050, the demand for copper is projected to increase 300% above current levels (Elshkaki et al., 2018). While copper is one of the most widely recycled metals, the recycled content in new products is expected to remain below 25% for the foreseeable future (Graedel et al, 2011). Accessing new and undeveloped copper orebodies is therefore critical to meeting projected demand.
