Anhydrous mineral separation method

Abstract

The invention discloses a mineral separation method. The mineral separation method comprises the following steps: to-be-separated granular raw ore is fed into an inner cavity of a transversely arranged separation cylinder of a separator, wherein the central axis of the separation cylinder is transversely arranged; the separation cylinder is driven to rotate around the central axis, and applying a magnetic field to the raw ore in the inner cavity around the periphery of the separation cylinder, so that the granules of the raw ore simultaneously move upwards from the bottom of the separation cylinder along the inner wall of the separation cylinder while advancing, and granules drop due to the gravity action, and the first granules which can be influenced by the magnetic field in the raw ore can be stirred and rolled in the upward moving and dropping processes, are mutually combined into material agglomerates, attached to the cylindrical wall of the separation cylinder, move upwards along with rotation of the cylindrical wall of the separation cylinder and reach a blanking area above the separation cylinder; and the first granules can drop to a receiving device of the separator in the blanking area by virtue of a blanking mechanism, and allowing the granules to leave the separator by virtue of the receiving device.

Description

technical field [0001] The present invention relates to the screening of minerals, more specifically, to a sorting method for anhydrous raw ore materials or tailings. Background technique [0002] Mineral resources are an important support for the development of the national economy and one of the indispensable elements for the survival and development of human society. As a mature industrial technology, mineral processing has a history of nearly a hundred years. However, under the condition that rich ore resources are gradually decreasing, the existing beneficiation technology and means have a serious problem of wasting mineral resources. [0003] Since various metal minerals exist in the form of mutual association, one mineral with high content is accompanied by one or more other minerals with relatively low content. For example, iron ore may also be accompanied by minerals such as sulfur ore, copper ore, and silicon ore. At present, my country's mineral processing indu...

AI Technical Summary

Problems solved by technology

This beneficiation method will waste many effective mineral components, and the tailings still contain many valuable mineral components

[0005] In addition, it is generally necessary to use water as a medium in beneficiation, but in water-scarce areas, or in beneficiation sites where it is inconvenient to access water sources at the beneficiation site, it is difficult for current beneficiation technologies to achieve high-efficiency mineral separation.
