Abstract

SE REFIERE A UN METODO PARA ELIMINAR EL POLVO DE UNA MINA, DONDE EL MINERAL OBTENIDO ES TRATADO CON UNA SOLUCION PARA LIXIVIAR SEGUIDA DE UNA EXTRACCION POR SOLVENTES, QUE COMPRENDE MOJAR EL POLVO CON UNA MEZCLA ACUOSA QUE CONTIENE: A) POR LO MENOS 10 ppm HASTA 1000 ppm, DE ALQUIL POLIGLUCOSIDO, CON UN GRADO DE POLIMERIZACION DE 1,4 A 1,6; DONDE, EL GRUPO ALQUIL CONTIENE UN PROMEDIO DE 8 A 12 ATOMOS DE CARBONO, DE FORMULA R1O(Z)a, SIENDO R1 UN RADICAL ALQUIL MONOVALENTE, Z UN RESIDUO DE GLUCOSA, Y a UN NUMERO ENTRE 1,4 Y 1,6; Y, B) UN MATERIAL AGLUTINANTE HIDROFILO. DONDE, LA MEZCLA ACUOSA PRODUCE POCA ESPUMA Y ES COMPATIBLE CON EL PROCESO DE EXTRACCION POR SOLVENTESREFERS TO A METHOD TO ELIMINATE THE DUST FROM A MINE, WHERE THE MINERAL OBTAINED IS TREATED WITH A SOLUTION TO LEACH FOLLOWED BY AN EXTRACTION BY SOLVENTS, WHICH INCLUDES WETTING THE DUST WITH A WATERY MIXTURE CONTAINING: A) AT LEAST 10 ppm UP TO 1000 ppm, OF ALKYL POLYGLUCOSIDE, WITH A DEGREE OF POLYMERIZATION OF 1.4 TO 1.6; WHERE, THE RENTAL GROUP CONTAINS AN AVERAGE OF 8 TO 12 CARBON ATOMS, OF FORMULA R1O (Z) a, R1 BEING A MONOVALENT RADICAL ALKYL, Z A RESIDUE OF GLUCOSE, AND A NUMBER BETWEEN 1.4 AND 1.6; AND, B) A HYDROPHILE BINDING MATERIAL. WHERE THE AQUEOUS MIXTURE PRODUCES LITTLE FOAM AND IS COMPATIBLE WITH THE SOLVENT EXTRACTION PROCESS
