Resumo: | Abstract Increasing throughput during the mining cycle operation frequently generates significant capital gains for a company. However, it is necessary to evaluate plant capacity and expand it for obtaining the required throughput increase. Therefore, studies including different scenarios, installation of new equipment and/or optimization of existing ones are required. This study describes the sampling methodology, sample characterization, modeling and simulation of Mineração Serra Grande industrial grinding circuit, an AngloGold Ashanti company, located in Crixás, State of Goiás, Brazil. The studied scenarios were: (1) adding a third ball mill in series with existing two ball mills, (2) adding a third ball mill in parallel with existing mills, (3) adding a vertical mill in series with existing mills and (4) adding high pressure grinding rolls to existing mills. The four simulations were carried out for designing the respective circuit, assessing the interference with existing equipment and installations, as well as comparing the energy consumption among the selected expansion alternatives. Apart from the HPGR alternative, all other three simulations resulted in the required P80 and capacity. Among the three selected simulations, the Vertimill alternative showed the smallest installed power. |
