Abstract
The invention discloses a method capable of enabling cassiterite to be separated from pyrrhotite. The method is characterized in that a separation device is hung above the surface of a shaking table, a hanging direction is perpendicular to a material supply direction, and the length completely covers the ore pulp width of the surface of the shaking table; after the shaking table normally works, ore pulp enters an ore feeding groove and is spread on the surface of the shaking table; a water feeding groove discharges flushing water; when the pyrrhotite passes through a lower part of the separation device, the partial pyrrhotite is attracted by permanent magnetic blocks in the separation device due to magnetic property and adsorbed at the bottom of each stainless steel box, the rest part is pulled to the surface of the ore pulp due to attraction of the permanent magnetic blocks in the separation device, and the pyrrhotite passes over table strips of the shaking table and reaches a tailing region under the action of the flushing water in the water feeding groove, so that the cassiterite is radically separated from the pyrrhotite. The method can radically prevent the pyrrhotite from being crowded in tin concentrates, thereby improving the grade of the tin concentrates and increasing the recovery rate of the tin concentrates; moreover, a system does not need any power and is simple in structure, safe, reliable, convenient to operate and low in manufacturing cost.
Description
Technical field
The present invention relates to a kind of method and system that cassiterite can be made to be separated with magnetic iron ore, belong to technical field of beneficiation.
Background technology
At present, in ore dressing plant, the valuable mineral can recycled from Tin concentrate is cassiterite, and the recovery of cassiterite adopts shaking table to reclaim mostly.
The principle that shaking table reclaims is, utilizes the larger specific gravity reclaiming mineral and non-recycled mineral poor.Wherein, the mineral that proportion is larger take the lead in being deposited in the riffling groove of shaking table surface bottom, along with the differential of the shaking table head of a bed is moved to concentrate district; And the comparatively light and mineral deposition that particle is thicker of proportion is on the surface of shaking table surface, is rinsed by the horizontal flushing water in shaking table feed trough, cross shaking table riffling, flow to mine tailing district, reach the object of separation.
But because of the often association of cassiterite and magnetic iron ore, if the content of magnetic iron ore is higher in raw ore, again because the proportion of cassiterite is 6.8 ~ 7.1 and magnetic iron ore proportion is 4.6 ~ 4.7, proportion difference is less.When separation by shaking table, magnetic iron ore can be got in Tin concentrate, causes both separation difficulty, affects grade and the rate of recovery of Tin concentrate.
Therefore, for containing the higher ore dressing plant of magnetic iron ore in raw ore, before selected shaking table, flotation or wet magnetic separator is often utilized to remove magnetic iron ore in advance.When flotation, because magnetic iron ore is difficult to activation, remove magnetic iron ore not thorough; After flotation, utilize cassiterite not have magnetic, and the magnetic feature of magnetic iron ore tool, residual magnetic iron ore removed by recycling wet magnetic separator, but because of ore pulp fluctuating range and frequency comparatively large, be also difficult to thoroughly remove totally.
Therefore, when shaking table reclaims cassiterite, magnetic iron ore can be got in Tin concentrate, reduces Tin concentrate grade and the rate of recovery.Utilize flotation and wet magnetic separator, thoroughly can not remove magnetic iron ore, when separation by shaking table, magnetic iron ore still can be got in Tin concentrate, thus reduces Tin concentrate grade and the rate of recovery.
