Abstract
SE PRESENTA UN PROCESO PARA RECUPERAR PLOMO, COMPRENDIENDO LAS FASES DE: ALIMENTAR SOSA CAUSTICA FUNDIDA, MINERAL BRUTO QUE CONTENGA PLOMO Y UN GAS QUE CONTENGA OXIGENO, DENTRO DE UNA ZONA DE REACCION QUE TENGA UNA TEMPERATURA DE 600 A 700 C, OBTENIENDOSE METAL DE COBRE EXTRAIDO DEL PROCESO Y UN SULFATO SODICO CONTENIENDO LA MASA FUNDIDA, CINZ, SULFUROS DE COBRE Y GANGA. LA MASA FUNDIDA SE DESCARGA DE LA ZONA DE REACCION Y SE SOMETE A UNA PRIMERA OPERACION DE LIXIVIACION PARA OBTENER, COMO RESULTADO, UNA PASTA FANGOSA, QUE REPRESENTA UNA MEZCLA DE PARTICULAS SOLIDAS DE SULFATO SODICO, SULFATOS DE CINC Y COBRE, GANGA Y UNA SOLUCION ACUOSA QUE CONTIENE ESENCIALMENTE SOSA CAUSTICA. POSTERIORMENTE, LA PASTA FANGOSA SE FILTRA PARA PRODUCIR UNA SOLUCION ACUOSA CONCENTRADA, QUE CONTIENE ESENCIALMENTE SOSA CAUSTICA Y UN RESIDUO SOLIDO. LA SOLUCION DE SOSA CAUSTICA CONCENTRADA SE SOMETE A UN ESPESAMIENTO POR EVAPORACION, Y LA MASA FUNDIDA DE SOSA CAUSTICA RESULTANTE SE LLEVA A LA ZONA DE REACCION. EL RESIDUO RESULTANTE SE SOMETE A UNA SEGUNDA OPERACION DE LIXIVIACION PARA OBTENER UNA SUSPENSION QUE SE FILTRA, PARA OBTENER POR ULTIMO UNA ESPECIE DE TORTA QUE REPRESENTA LAS PARTICULAS SOLIDAS DE LOS SULFUROS DE CINC Y PLOMO RESPECTIVAMENTE, Y GANGA QUE TIENE, ABSORBIDA SOBRE SU SUPERFICIE, UNA SOLUCION DE SULFATO SODICO Y UNA SOLUCION ACUOSA CONTENIENDO ESENCIALMENTE SULFATO SODICO. LA CITADA SOLUCION SE SOMETE A UN TRATAMIENTO ELECTROQUIMICO PARA OBTENER ACIDO SULFURICO EXTRAIDO DEL PROCESO, Y ALCALI QUE SE LLEVA A LA CITADA PRIMERA OPERACION DE LIXIVIACION. LA ESPECIE DE TORTA SE LAVA PARA OBTENER UNA SOLUCION DE SULFATO SODICO, QUE SE LLEVA DESPUES A UNA SEGUNDA OPERACION DE LIXIVIACION.
