It can be argued that adoption of SX-EW across the industry enabled the exploitation of relatively low-grade deposits (< 0.5% Cu by weight) through heap and dump leaching (Kordosky 2002) and by extension, bioleaching.Higher-grade deposits can be processed more efficiently through direct smelting or smelting of flotation concentrates.
