2.1Leaching. Mostcopper leachingis done by piling brokenore(∼0.5% Cu) into flat-surface, 3–10m high, 10 4 –10 5 m 2 heaps oforeand then sprinkling dilute sulfuric acid lixiviant on to theheapsurface. The lixiviant trickles down through theheapand leachescopperfrom its minerals to produce a pregnantleachsolution containing 1–5kg Cum −3.
