Proceso de separaci\u00f3n por gravedad de la wolframita<\/h2><\/div><\/div>\n\t
\n\t\t
\n\t\t\t

El mineral de wolframita tiene una alta tasa de agotamiento, baja ley, tama\u00f1o de grano grueso, alta densidad, baja dureza, f\u00e1cil formaci\u00f3n de lodo y color profundo, que se extrae principalmente mediante el proceso de separaci\u00f3n por gravedad. La producci\u00f3n china de beneficio de mineral de wolframita tiene una historia de m\u00e1s de 70 a\u00f1os y ha acumulado una rica experiencia, que puede resumirse en las siguientes partes.
\n1. Preenriquecimiento, lanzamiento temprano de la roca est\u00e9ril, luego lavado, deslimado, clasificaci\u00f3n, trituraci\u00f3n.
\nLa relaci\u00f3n de diluci\u00f3n de la miner\u00eda de wolframita es generalmente alrededor de 80%. La cantidad de roca circundante en el mineral es grande, y son f\u00e1ciles de distinguir con la roca que contiene wolframita. La preselecci\u00f3n de la roca est\u00e9ril aumenta la capacidad y la eficacia del proceso de beneficio, y reduce el desgaste de la trituradora de roca.<\/p>\n

2. Separaci\u00f3n por gravedad, clasificaci\u00f3n y selecci\u00f3n. Concentrador Jig - mesa vibratoria para recuperar la wolframita de part\u00edculas gruesas.<\/p>\n

3. Concentraci\u00f3n de limo fino de wolframita
\nEl limo fino de wolframita incluye el limo primario y el secundario, que representan alrededor de 10% del mineral original. La ley de tungsteno es superior a la del mineral original, la ley es de 14% a 15%. Extraer tungsteno del limo es un m\u00e9todo importante para mejorar la tasa de recuperaci\u00f3n de tungsteno.
\nLas m\u00e1quinas de concentraci\u00f3n de lodos de wolframita cuentan con mesas agitadoras, concentradores centr\u00edfugos, tolva de cinta, flotaci\u00f3n y separaci\u00f3n magn\u00e9tica. La tasa de recuperaci\u00f3n de lodo fino ha aumentado de 10% ~ 50% a 60%~70%.<\/p>\n
