Embodiment Construction

[0139] 1. Mineral processing test of Shouwangfen copper-iron mine in Hebei Province

[0140] The mine is a skarn-type copper-iron deposit. Ore is divided into three categories:

[0141] (1) White ore (talc, actinolite, diopside contains copper, and the color is whitish), the metal mineral intercalation particle size is coarse, and the selectability is good;

[0142] (2) Black ore (serpentine, magnetite containing copper, black in color), the ore is dense in texture, strong in toughness, and the distribution of metal minerals is fine, so it is a refractory ore;

[0143] (3) Magnetite copper-containing ore has high hardness, high density, brittle texture, and coarse metal mineral intercalation, which is a medium optional ore.

[0144] Metal minerals in the ore include magnetite, pyrrhotite, hematite, chalcopyrite, azurite, black copper ore, malachite, aluminum pyroxene, sphalerite, sulfur cobalt ore, gold and silver ore, silver Gold ore, silver-silver ore, native gold, etc. ...

Abstract

The invention relates to a magnetoelectric combined separation method for a plurality of element minerals and equipment thereof, which belongs to a field of mineral processing technology, mineral processing equipment and comprehensive utilization of mineral resources in mineral processing industry. Through comprehensive utilizing modern technologies such as a magnetic separation method, an electric separation method, a reverse rotating magnetic field, corona and an electrostatic composite electric field and a new electrode structure, isotopic ion excitation source, an electrostatic focusing quality analyzer, a particle speed selector, a magnetic field quality analyzer, etc., no water and chemicals are demanded; comprehensive treatment of the plurality of elements minerals with complex components and separation of minerals of fine particles which are difficult to be treated realize comprehensive separation operation of the plurality of mineral elements in the minerals and solve the difficult problems that the plurality of the element minerals in natural minerals or tail minerals can not be separated by current mineral processing technology and mineral processing equipment and content of harmful substances such as sulfur and phosphorus in iron concentrate in steel smelting industry is too high. The invention has the advantages of simple mineral processing technology, high equipment efficiency, high grade concentrate, low mineral processing cost, energy saving, environment protection and high-efficiency development and comprehensive utilization of national mineral resources.

Description

1. Technical field [0001] The invention relates to a method and equipment for magnetoelectric joint separation of various elemental minerals, belonging to the field of mineral processing technology and mineral processing equipment in the mineral processing industry, and the efficient development and comprehensive utilization of mineral resources. 2. Background technology [0002] At present, the mineral processing technology for mineral separation usually adopts the following methods: gravity separation, flotation, magnetic separation, electric separation, chemical mineral processing, and almost all the equipment manufactured by the mineral processing technology can only be used for the main separation. 1-2 kinds of mineral products, other mineral products in the minerals are discarded in large quantities because they cannot be separated or the cost of mineral separation is too high, resulting in a large waste of mineral resources. [0003] Magnetic separation is a mineral s...
