2.1 Leaching. Most copper leaching is done by piling broken ore (∼0.5% Cu) into flat-surface, 3–10m high, 10 4 –10 5 m 2 heaps of ore and then sprinkling dilute sulfuric acid lixiviant on to the heap surface. The lixiviant trickles down through the heap and leaches copper from its minerals to produce a pregnant leach solution containing 1–5kg Cum −3.
Heap Leaching In Mine Design Strong Ability. Average ore grades recovered by heap leaching are 0.9 grams of gold per metric ton of ore 0.03 ozshort ton, with an extreme cutoff grade of 0.2 grams of gold per metric ton 0.006 ozshort ton at the round mountain mine in central nevada spickelmier 1993.Relative ore grade dictates the choice of two heap leaching methodologies.

2015-1-22 · Heap leaching is a tried and tested mining technique enabling the processing of different kinds for a strong environmental impact. This BREF document covers fourteen different metals, including gold, that are mined and/or processed in the European Union (EU-15), the acceding
The power of these models lies in their ability to rapidly and reliably show the effect of alternative configurations and leaching conditions. Developing the model forces a rigorous examination of the process design. Simulation results are often counter-intuitive,
