El procesamiento de minerales<\/a> en plantas de concentraci\u00f3n<\/a> incluye una serie de operaciones sucesivas cuyo resultado es la separaci\u00f3n de los componentes minerales de las impurezas. Seg\u00fan su finalidad, los procesos de procesamiento de minerales se dividen en preparatorios<\/a>, principales<\/a> (de concentraci\u00f3n) y auxiliares<\/a> (finales).<\/p>\n

Los procesos preparatorios est\u00e1n dise\u00f1ados para la liberaci\u00f3n de los minerales como resultado de la destrucci\u00f3n de las uniones entre los minerales y la roca est\u00e9ril o de las uniones de algunos minerales con otros, formando una mezcla mec\u00e1nica de part\u00edculas y fragmentos de diferente composici\u00f3n mineral, as\u00ed como para llevar los minerales al tama\u00f1o requerido para el enriquecimiento posterior. Los procesos preparatorios incluyen la trituraci\u00f3n<\/a> y la molienda<\/a>.<\/p>\n

En las plantas de concentraci\u00f3n y en las plantas metal\u00fargicas, la trituraci\u00f3n y la molienda de los minerales se realizan con un alto grado de reducci\u00f3n del tama\u00f1o de las part\u00edculas antes del enriquecimiento. Por ejemplo, en algunos casos los minerales deben molerse hasta un tama\u00f1o de part\u00edcula inferior a 0,1 mm.<\/p>\n

Lograr un grado tan alto de fragmentaci\u00f3n<\/a> en una m\u00e1quina de trituraci\u00f3n es casi imposible. Debido a su dise\u00f1o, las m\u00e1quinas de trituraci\u00f3n y molienda (trituradoras y molinos) funcionan eficazmente solo dentro de un grado de molienda<\/a> limitado. Por lo tanto, una forma racional de triturar y moler el material desde el tama\u00f1o original hasta el tama\u00f1o requerido es utilizar varias m\u00e1quinas de trituraci\u00f3n y molienda que funcionen de manera secuencial.<\/p>\n

\"mineral_processing_at_concentrating_plants_2\"<\/a><\/p>\n

Dependiendo del tama\u00f1o del material triturado y del producto triturado, las etapas de trituraci\u00f3n tienen nombres especiales: la primera etapa \u2013 trituraci\u00f3n gruesa (de 1500\u2013300 mm a 350\u2013100 mm); la segunda etapa \u2013 trituraci\u00f3n secundaria (de 350\u2013100 mm a 100\u201340 mm); la tercera etapa \u2013 trituraci\u00f3n fina (de 100\u201340 mm a 30\u20135 mm).<\/p>\n

La operaci\u00f3n posterior, a la que entra el material despu\u00e9s de la trituraci\u00f3n secundaria o fina (fragmentos menores de 50 mm), se denomina molienda. Como resultado del proceso de molienda se obtiene un producto cuyo tama\u00f1o de part\u00edcula es inferior a 5 mm.<\/p>\n

Entre los elementos de trituraci\u00f3n de las trituradoras existe un espacio que se llena con el material bajo carga y permanece libre en vac\u00edo. Gracias a este \u201cespacio de calibraci\u00f3n\u201d, las trituradoras producen un producto en trozos con predominio de fracciones gruesas. En los molinos, los elementos de molienda est\u00e1n separados por una capa de material solo bajo carga y, en vac\u00edo, entran en contacto. Los molinos producen un producto pulverulento con predominio de fracciones finas, ya que el espacio de trabajo entre los medios de molienda<\/a> (bolas de molienda) es pr\u00e1cticamente cero.<\/p>\n

As\u00ed, gracias al uso sistem\u00e1tico de trituradoras<\/a> y molinos<\/a>, se logra la liberaci\u00f3n de los minerales para formar una mezcla mec\u00e1nica de part\u00edculas de diferente composici\u00f3n mineral, adecuada para la posterior separaci\u00f3n en el proceso de enriquecimiento<\/a>, as\u00ed como la operaci\u00f3n de homogeneizaci\u00f3n de minerales, que puede realizarse en minas, canteras y plantas de concentraci\u00f3n.<\/p>\n","protected":false},"excerpt":{"rendered":"
