Problems solved by technology

However, since the size of the centrifugal force and the rising water flow cannot interact and match each other, it can only be used for concentration, desliming and separation of minerals with large differences in specific gravity.
It is difficult to select mineral elements whose specific gravity difference is less than 1.5, and the separation effect is not ideal
Mineral elements whose specific gravity difference is less than 1.25 cannot be effectively sorted

Embodiment Construction

[0005] The basic beneficiation method is as follows:

[0006] 1. Weakly magnetic or non-magnetic minerals→primary separation and enrichment by type 2 layering machine→impurity removal and purification by type 1 layering machine→concentrate (product).

[0007] For weakly magnetic or non-magnetic minerals, the layered concentrator manufactured by the above mineral processing principle, the mineral processing method that implements the gravity separation process is called "layered method".

[0008] 2. Magnetic minerals → magnetic separation → a type of layering machine selection impurity removal and purification → concentrate (product).

[0009] For medium and strong magnetic minerals, the mineral separation method using a magnetic separation machine and a layered separation machine manufactured using the above separation principles is called the "magnetic separation method".

Abstract

The mineral element separating process includes the following steps: crushing, sieving, grinding, grading, initial sorting in type-II laminating machine, and eliminating impurity and purification in type-I laminating machine. The present invention has smart structure and wide separation range, can separate mineral elements with specific weight difference within 0.5, and makes it possible to treat tail mineral and dregs to realize comprehensive utilization.

Description

Technical field: [0001] The invention relates to a separation method, in particular to a mineral element separation method. Background technique: [0002] The ore pulp flows into the barrel of the concentrator at a certain tangent through the pulp inlet, and moves circularly along the barrel under the action of centrifugal force. The heavy ore particles are thrown to the edge of the barrel by centrifugal force and settle down along the barrel wall. The light ore particles are pushed to the liquid surface by the rising water flow. This is the working principle of general centrifugal gravity separation machinery. However, since the magnitude of the centrifugal force and the rising water flow cannot interact and match each other, it can only be used for concentration, desliming and separation of minerals with large differences in specific gravity. It is difficult to separate mineral elements whose specific gravity difference is less than 1.5, and the selection effect is not ...
