Abstract
DONDE LOS PROCESOS COMPRENDEN: a) PROPORCIONAR UNA SOLUCION CARGADA DE LIXIVIACION QUE COMPRENDE VALORES DE COBRE; b) PONER EN CONTACTO DICHA SOLUCION CON UNA FASE ORGANICA QUE CONTIENE UN EXTRACTANTE DE COBRE A UNA TEMPERATURA DE EXTRACCION, Text, PARA FORMAR UNA FASE ORGANICA CARGADA QUE TIENE LOS VALORES DE COBRE; Y, c) PONER EN CONTACTO LA FASE ORGANICA CARGADA RESULTANTE CON UNA SOLUCION DE REEXTRACCION ACUOSA A UNA TEMPERATURA DE REEXTRACCION, Treext, PARA FORMAR UNA SOLUCION DE REEXTRACCION ENRIQUECIDA DE COBRE, EN DONDE LA DIFERENCIA EN LA TEMPERATURA (DT) ES LA TEMPERATURA DE REEXTRACCION MENOS LA TEMPERATURA DE EXTRACCION SIENDO DICHO DT MENOR O IGUAL A 10°C. SE UTILIZAN UNO O MAS INTERCAMBIADORES DE CALOR PARA DISMINUIR LA Treext, TRANSFIRIENDO CALOR DESDE UN ELECTROLITO POBRE QUE SALE DE LA ETAPA DE RECUPERACION ELECTROLITICA A LA SOLUCION DE REEXTRACCION DE COBRE O A LA FUENTE DE AGUA, FORMANDO UN ELECTROLITO POBRE ENFRIADO USADO AL MENOS COMO UNA PORCION DE LA SOLUCION DE REEXTRACCION ACUOSA; O SE UTILIZAN PARA ELEVAR LA TEMPERATURA DE EXTRACCION DE LA SOLUCION CARGADA DE LIXIVIACIONWHERE THE PROCESSES INCLUDE: a) PROVIDE A SOLUTION LOADED WITH LEACHING THAT INCLUDES COPPER SECURITIES; b) PUT IN CONTACT SAID SOLUTION WITH AN ORGANIC PHASE CONTAINING A COPPER EXTRACTANT AT AN EXTRACTION TEMPERATURE, Text, TO FORM A CHARGED ORGANIC PHASE THAT HAS THE VALUES OF COPPER; AND, c) CONTACT THE RESULTING CHARGED ORGANIC PHASE WITH AN AQUEOUS REEXTRACTION SOLUTION AT A REEXTRACTION TEMPERATURE, Treext, TO FORM AN ENRICHED COPPER REEXTRACTION SOLUTION, WHERE THE DIFFERENCE IN TEMPERATURE (DT) IS RE-EXTRACTION MINUS THE EXTRACTION TEMPERATURE, SAID DT BEING LESS OR EQUAL TO 10 ° C. ONE OR MORE HEAT EXCHANGERS ARE USED TO DECREASE Treext, TRANSFERRING HEAT FROM A POOR ELECTROLYTE THAT COMES OUT OF THE ELECTROLYTIC RECOVERY STAGE TO THE COPPER RE-EXTRACTION SOLUTION OR TO THE WATER SOURCE, FORMING A POOR ELECTROLYTE USER PORTION OF THE AQUEOUS REEXTRACTION SOLUTION; OR THEY ARE USED TO RAISE THE EXTRACTION TEMPERATURE OF THE SOLUTION CHARGED WITH LEACHING
