Mining Scheduling with Geopit

There are two methods for mining scheduling: the Maximizing Method and the Stationary Method.

Maximizing Method
For a long time, mine planning emphasized the maximization of the enterprise’s cash flow. This approach takes into account a preference for high grade ores (rich ore has more value) that results in mining high grades at the beginning, and low grades at the end of the mine life cycle. For ore types such as gold or copper, this is the best method to plan the mine sequence.

Stationary Method
Industrial ore types, such as iron, manganese, phosphate, or limestone for cement, require a different approach, once they have been subjected to rigid quality specifications to determine constant grades. To take these characteristics into account, it is necessary to change the mining scheduling method. In this new scenario, the grades must remain constant, so that the ore retains its commercial value.

Mining Scheduling with Geopit
Geopit is a software program used for mining scheduling through the stationary method. It is used by major companies, such as CVRD, Votorantim, Bunge Fertilizantes, Holcim, FMG (Australia). It was developed for mining scheduling that incorporates sophisticated mass and grade control (blending), along with many tools that give the user total control of the process.

SRK Consulting represents Geopit worldwide, except in Australia.
