Abstract

DONDE UNA SOLUCION LIXIVIANTE SE PONE EN CONTACTO CON UNA MENA PARA EXTRAER EL METAL DEL MISMO, SIENDO DICHA SOLUCION DE 1 ppm A 1000 ppm DE UNA AYUDA DE DRENAJE QUE COMPRENDE UN ALCOHOL ALIFATICO ETOXILADO DE FORMULA: HO[CH2CH2-O]nR DONDE R ES C4-C20 ALQUENILO Y n ES DE 2 A 20. SE REFIERE ADEMAS A UN METODO PARA LIXIVIAR ORO A PARTIR DE UNA MENA QUE LO CONTIENE, DONDE UN SISTEMA LIXIVIANTE BASADO EN CIANURO Y LA AYUDA DE DRENAJE SE CONTACTA CON LA MENA PARA RETIRAR ORO, SIENDO EL pH DEL SISTEMA LIXIVIANTE DE 9 A 11,5WHERE A LEACHING SOLUTION IS CONTACTED WITH AN ORE TO EXTRACT THE METAL FROM IT, SAID A SOLUTION FROM 1 ppm TO 1000 ppm OF A DRAINAGE AID THAT INCLUDES AN ETHOXYLATED ALIPHATIC ALCOHOL OF FORMULA: HO [CH2CHON-O] IT IS C4-C20 ALKENYL AND n IS FROM 2 TO 20. IT ALSO REFERS TO A METHOD TO LEACH GOLD FROM A MENA CONTAINING IT, WHERE A CYANIDE-BASED LEACHING SYSTEM AND THE DRAINAGE ASSISTANCE IS CONTACTED WITH THE MENA TO REMOVE GOLD, BEING THE pH OF THE LEACHING SYSTEM FROM 9 TO 11.5
