Many mining companies want to be able to accurately model leach lag so they can develop truly optimal mine plans for leach operations. We are pleased to let you know that the wait is almost over: this major industry-first innovation will be a part of Minemax Scheduler 6.3, and will soon be available for all maintained users.

Traditional modeling methods in strategic mine planning software assume that ore is completely processed at the time of delivery, and do not consider time-delayed ore processing as apparent in leaching flowsheets. However, a typical leach cycle can take anywhere from one month to multiple years. This means the financial model used during the schedule optimization won’t be accurate, and the resulting schedule will not accurately account for metal production or the revenue associated with it. Currently, many mine planners end up post-processing their schedule outside their strategic mine planning software in order to account for this delayed recovery.

Armed with Minemax Scheduler 6.3 with Leach Modeling, mine planners will be able to use explicit time-delayed recoveries to accurately model leach lag during the schedule optimization. This means they will have the guarantee that their schedule achieves the best NPV and their reporting is accurate. They will get what they have been waiting for – the truly optimal schedule.

Minemax Scheduler 6.3 will also include further advanced Capital Expenditure functionality such as capacity contractions and better ability to control Capex spending.
