Abstract

PROCEDIMIENTO PARA CONCENTRAR SILVITA EN UN SISTEMA DE FLOTACION DE MINERAL SILVINITA. AL SISTEMA DE FLOTACION SE AÑADE, COMO DEPRESOR SELECTIVO, UNA CANTIDAD EFICAZ DE UN COPOLIMERO O SALES DEL MISMO SOLUBLES EN AGUA. EL COPOLIMERO TIENE LA ESTRUCTURA GENERAL QUE SE INDICA, EN DONDE R Y R SON, INDIVIDUALMENTE, HIDROGENO O UN RADICAL METILO, X ES HIDROGENO, METAL ALCALINO O EL ION AMONIO, N Y M SON NUMEROS ENTEROS TALES QUE EL GRADO DE HIDROLISIS SEA DE 5 A 66% Y N, M Y A TIENEN UN VALOR NUMERO TAL QUE EL PESO MOLECULAR TOTAL DEL COPOLIMERO SEA DE 200 A 85.000. SE DEJA QUE EL DEPRESOR REACCIONE QUIMICAMENTE CON LA SUPERFICIE MINERAL DE LA GANGA PARA PRODUCIR PELICULAS PROTECTORAS INSOLUBLES DE NATURALEZA HUMECTABLE QUE NO REACCIONARAN CON LOS COLECTORES. FINALMENTE SE SEPARA LA SILVINITA DE LA GANGA DEPRIMIDA.
