    • Gim-Krumm, Minghai; Donoso, Pablo; Zuñiga, Rommy; Estay, Humberto; Troncoso, Elizabeth (Elsevier B.V., 2018)
      Human digestion is a complex process that involves several phenomena: chemical and enzymatic reactions, absorption, hydrodynamic processes, and mass transfer. The most accurate way to determine the bioavailability of ...
    • Estay, Humberto; Troncoso, Elizabeth; Ruby-Figueroa, René; Romero, Julio (MDPI, 2018-04)
      Cyanide recovery in the gold-mining industry is a crucial step in terms of the cost of operation. Currently, a process such as AVR (acidification, volatilization and recycling), based on packed towers for stripping and ...
    • Estay, Humberto; Díaz Quezada, Simón (Springer, 2020)
      The heap leaching process has been widely used for recovering different metals since its first application at the end of the 1960s. In Chile, copper production via heap leaching has accounted for between 30 and 40% of ...
    • Estay, Humberto (Elsevier B.V., 2018)
      © 2018 Elsevier B.V. Almost twenty years ago, the first paper about the SART process was published, and eleven years ago the first SART plant was commissioned and operated at Telfer mine, in Australia. Up to this moment, ...
    • Estay, Humberto (Elsevier, 2018)
      Almost twenty years ago, the first paper about the SART process was published, and eleven years ago the first SART plant was commissioned and operated at Telfer mine, in Australia. Up to this moment, seven SART processes have ...
    • Rodríguez, Bárbara; Armendáriz Ontiveros, María; Hernández Quezada, Rodrigo Alejandro; Huitron Segovia, Esther; Estay, Humberto; García García, Alejandra; García, Andreina (MDPI, 2020)
      The influence of the lateral size and the content of graphene oxide (GO) flakes in specific oxygenate functional groups on the anti-biofouling properties and performance of thin-film composite membrane (TFC) was studied. ...
    • Díaz Aburto, Isaac; Hidalgo, Jacqueline; Fuentes Mendoza, Eliana; González Poggini, Sergio; Estay, Humberto; Colet Lagrille, Melanie (Korean Electrochemistry Society, 2021)
      Mo,Cu-doped CeO2 (CMCuO) nanopowders were synthesized by the nitrate-fuel combustion method aiming to improve the electrical and electrochemical properties of its Mo-doped CeO2 (CMO) parent by the addition of copper. An ...
    • Estay, Humberto; Gim-Krumm, Minghai; Seriche, Gabriel; Quilaqueo, Michelle; Barros, Lorena; Ruby Figueroa, René; Romero, Julio; Troncoso, Elizabeth (Elsevier, 2020)
      The SART (Sulfidization, Acidification, Recycling and Thickening) process has been successfully installed to recover cyanide and copper in seven worldwide gold cyanidation plants in the last 15 years. This technology has ...
    • Estay, Humberto; Troncoso, Elizabeth; Ruby Figueroa, Rene; Romero, Julio (Elsevier, 2018)
      Gas filled membrane absorption process (GFMA), or hollow fiber gas membranes process (HFGM) can replace two units operations (absorption and stripping) in a unique stage based on membrane contactors. But its application ...
    • González, Carol; Abarca González, Daniela Alejandra; Zúñiga, Rommy N.; Estay, Humberto; Troncoso, Elizabeth (MDPI, 2020)
      This work deepens our understanding of starch digestion and the consequent absorption of hydrolytic products generated in the human small intestine. Gelatinized starch dispersions were digested with -amylase in an in ...
    • Quezada, Rodrigo; Quintero Giraldo, Yurieth; Salgado Herrera, José; Estay, Humberto; García, Andreina (MDPI, 2020)
      Type of metal and metal-oxide NPs added to modify Thin-Film Composites Reverse Osmosis Membranes (TFC-RO) can alter their anti-biofouling properties by changing the dissolution process. The development of a mathematical ...
