Enrichment of valuable minerals from ore using the heap extraction method |
| abstract |
The present invention relates to a process for extracting valuable metals from sulfide ore, which includes the steps of crushing ore in a primary crusher (14) to a size of approximately 40 cm and less, passing the crushed ore through one or more of the following beneficiation processes such as bulk sorting ( 16) and sieving (20) followed by coarse flotation (46/50) or gravity separation or magnetic separation. A stream (54) of waste from the preconcentration process or processes having a particle size greater than 100 μm is placed in a pile (26) and subjected to a pile leach. This integrated process uses the beneficiation techniques best suited to the characteristics of a specific ore body; and during the enrichment, a low-grade stream is formed at the same time, which gives a significantly higher recovery than can be achieved with normal high-leaching of low-grade unsorted ore. |
