摘要: Abstract Although the process of heap leaching is an established technology for treating minerals, such as copper, gold, silver, uranium and saltpeter, well remediating soil, no studies to date have investigated optimization. This work presents a methodology design planning systems optimize process. consists creation superstructure that represents set alternatives search optimal solution; from this superstructure, mixed integer nonlinear programming (MINLP) model was generated, BARON-GAMS solver used find solution. method applied extraction copper with one, two three heaps, effects price, ore grade other variables were analyzed each system. From results, it can be concluded processes, including issues.
