Abstract

abstract the present disclosure is directed to a process for recovering a precious metal from a pregnant leach solution using a resin extractant. the precious metal is eluted from the loaded resin using an eluant comprising trithionate. the barren resin is contacted with a sulfide, bisulfide, and/or polysulfide to convert sorbed trithionate to thiosulfate. the desorbed thiosulfate is contacted with an oxidant and converted to trithionate for eluant recycle. 5508-80-pct ************************************************** tradução do resumo resumo patente de invenção: "método para recuperar materiais preciosos e cobre a partir de soluções lixiviadas". a presente invenção refere-se a um processo para recuperar um metal precioso a partir de uma solução lixiviada fértil utilizando um extratante do tipo resina. o metal precioso é eluído da resina carregada utilizando um eluente compreendendo tritionato. a resina exaurida (barren resin) é colocada em contato com sulfeto, bissulfeto e/ou polissulfeto para converter o tritionato sorvido em tiossulfato. o tiossulfato dessorvido é colocado em contato com um oxidante e convertido em tritionato para reciclo do eluente. 6/3
