摘要： The disclosed invention provides a process for enhanced recovery of one or more metal values from heap and/or dump leaching of ores containing the metal values, the process comprising: (a) providing a high grade leach solution obtained by heap or dump leaching of fresh high grade ore containing a first metal value; (b) subjecting the high grade leach solution to a first solvent extraction of the first metal value and applying the resulting first aqueous raffinate to leach fresh high grade ore; (c) providing a low grade leach solution obtained by heap or dump leaching of partially leached ore or fresh low grade ore of the first metal value; and (d) subjecting the low grade leach solution to a second solvent extraction of the first metal value, separate from the first solvent extraction of the first metal value, and applying the resulting separate, second aqueous to leach partially leached ore or fresh low grade ore, wherein the first and second aqueous raffinates are not intermixed prior to being applied to their respective ores for leaching. Alternatively, the first and second raffinates may be intermixed prior to being applied to their respective ores for leaching, providing that the aqueous raffinate applied to fresh high grade ore comprises at least 60% by volume of the first aqueous raffinate and the aqueous raffinate applied to partially leached ore or fresh low grade ore comprises at least 60% by volume of the second aqueous raffinate.

摘要： Suggested is an improved process for metal recovery from ore using agitation leaching comprising dividing leaching of the crushed and mined ore into at least two sequential leaching-solids-liquid separation-solvent extraction sub-circuits, with no significant dilution during solids-liquid separation in these units, and the raffinate from solvent extraction being recycled back to the leaching, with the underflow pulp from the second liquid-solids separator being sent to a final solid-liquid separator, with water washing, from which the washed solids are sent to disposal and the clarified aqueous wash solution is sent to a final solvent extraction, with some or all of the metal-depleted aqueous raffinate from this final solvent extraction being optionally neutralized, and/or being circulated back to the third solid-liquid separation as wash solution and/or to recovery of other metals and/or to disposal to maximize metal recovery and maintain water balance.
