THAMES CANTOLLA, Martin Ignacio; VALDEZ, Silvana Karina  y  ORCE SCHWARZ, Agustina Maria. Multi-criteria selection for the processing of lithium brines in Argentina. Ing. Ind. [online]. 2021, vol.42, n.3, pp. 78-91.  Epub 23-Oct-2021. ISSN 1815-5936.

One of the most critical and complex steps, in mining, is selecting the appropriate production method, based on multiple parameters. This makes it difficult and therefore the importance of developing and 27 sub-criteria, to evaluate 6 methods of extraction of lithium from brine (alternatives). A hierarchical structure with three levels is proposed for the analysis. The best alternative was obtains based on a tool that facilitates this task. The objective of this work is to use the Fuzzy Analysis Hierarchical Process (FAHP) to develop a model for decision making with multiple criteria that allow selecting appropriate lithium brine mining methods in Northwest Argentina. The model developed considers 5 criteria global evaluation. The best alternative was obtained based on global evaluation. This tool can be applied for decision-making by new mining companies in the sector.
