    • A comminution model for secondary fragmentation assessment for block caving 
      Gómez, René; Castro Ruiz, Raúl; Casali Bacelli, Aldo; Palma, Sergio; Hekmat, Asieh (Springer, 2017)
      Predicting the rock fragmentation obtained in drawpoints or secondary fragmentation is crucial in Block caving application since many engineering decisions are based on this key variable. These can include drawpoints size ...
    • Control of a grinding mill circuit using fractional order controllers 
      Águila Camacho, Norelys; Le Roux, Johan D.; Duarte Mermoud, Manuel; Orchard Concha, Marcos (Elsevier, 2017)
      This paper presents the design and application of fractional single-input–single-output (SISO) controllers to a grinding mill circuit, which is a multiple-input–multiple-output (MIMO) process. Two kinds of controllers are ...
    • Fractional order controllers for throughput and product quality control in a grinding mill circuit 
      Aguila Camacho, Norelys; Duarte Mermoud, Manuel; Orchard Concha, Marcos (Elsevier, 2020)
      This paper presents the design and application of a multiple-input–multiple-output fractional order proportional-integral (MIMO FOPI) controller to a grinding mill circuit. The MIMO FOPI controller pa- rameters are tuned ...
    • Heating pre-treatment of copper ores and its effects on the bond work index 
      Cisternas, Nataly; Tobosque, Pablo; Sbarbaro, Daniel; Munnier González, Carlos Roberto; Kracht Gajardo, Willy Andrés; Carrasco, Claudia (MDPI, 2022)
      Comminution is the stage with the largest energy consumption in the mining process. Therefore, several pre-treatments have been proposed to reduce the energy requirements of this stage. This work analyzed the effect of a ...
