Jig gravity separation process of pyrite

Abstract

The invention provides a jigging gravity separation process for pyrite, the steps of which are as follows: firstly, the mixture of the ground pyrite and waste rock monomer is transported to the first jigging box, and the power driving device transmits the power to the first jigging box To the agitation mechanism, the agitation mechanism makes the medium water in the first jigging box and the second jigging box produce sawtooth wave vibration, and the first jigging box performs a concentrate gravity separation on pyrite and waste rock monomers and concentrates Deposited on the bottom of the first jigging box; then, the power drive device transmits the power to the transmission mechanism, and the transmission mechanism guides the pyrite, waste rock monomer and medium water in the first jigging box to the second jigging box Then, the second jigging box performs secondary concentrate gravity separation on pyrite and waste rock monomers, and the concentrate is deposited on the bottom of the second jigging box, and the tailings are discharged from the hopper of the second jigging box Discharging; in the process of step 1 to step 3, the discharge device dehydrates and discharges the concentrate at the bottom of the first jigging box and the bottom of the second jigging box.

Description

technical field [0001] The invention relates to a beneficiation jig machine, in particular to a jigging gravity separation process of pyrite. Background technique [0002] The jig machine is a kind of mineral separation machine, which uses the difference in density to re-select minerals and waste rocks. Generally, the density of minerals is greater than that of waste rocks. The minerals and waste rocks are separated by strong vibration of sawtooth water waves, so that the minerals It is deposited at the bottom of the medium water, and the waste rock is floating on the top of the medium water. During the beneficiation process of pyrite, the ground mixture of pyrite and waste rock is transported to the hydraulic jig by a belt conveyor. Gravity separation is carried out, and the concentrate (pyrite) and tailings (waste rock monomer and a small amount of pyrite) are obtained in one separation, the concentrate sinks to the bottom of the jigging chamber, and the tailings are suspe...

AI Technical Summary

Problems solved by technology

[0003] Ordinary jigging machines vibrate the water medium in a sawtooth wave through the agitation of the diaphragm at the bottom of the jigging chamber. Since the diaphragm needs to overcome the pressure and gravity of the medium water, each diaphragm needs to be driven and agitated by a separate motor. The disadvantage is that The energy consumption is high, and the pressure borne by the diaphragm is relatively large and easy to be damaged. In order to solve the above-mentioned problems, the inventors designed a kind of ingenious structure, simple principle, single motor and double jigging chamber, which can continuously carry out pyrite ore separation and beneficiation efficiency.
