Embodiment 1

[0025] The neutral leaching pH of the roasted ore is 4.5, and the 500ml zinc sulfate solution with a germanium content of 0.08mg / L is statically placed in a permanent magnetic field strength of 15T for 30 minutes, and the supernatant Ge is measured to be 0.062mg / L.

Embodiment 2

[0027] A 500ml zinc sulfate solution with a neutral leaching pH of 5.0 and a germanium content of 0.46mg / L of the roasted ore was placed in a permanent magnetic field of 300T for a holding time of 50 minutes, and the supernatant Ge was measured to be 0.07mg / L.

Embodiment 3

[0029] The neutral leaching pH of the roasted ore is 5.4, and the 500ml zinc sulfate solution with a germanium content of 1.65mg / L is statically placed in a permanent magnetic field strength of 800T for 60 minutes, and the supernatant Ge is measured at 0.064mg / L.

[0030] In the present invention, germanium is a charged colloid in the zinc sulfate solution. Under the action of a magnetic field, the charged germanium colloid moves in a directional direction and condenses into large particles, thereby realizing the purification of germanium in the zinc sulfate solution. The magnetic field generator of the present invention The magnetic field used is a permanent magnetic field or an electromagnetic field. The germanium in the zinc sulfate solution can be condensed into large particles under the action of the magnetic field, which has a good removal effect on germanium, short operation time, no need to input raw materials, low production cost, and labor intensity small.

Abstract

The present invention relates to a purification method of germanium in zinc sulfate solution by using magnetic field and belongs to the field of metallurgical and chemical industry. This method comprises the following steps: 1) passing a neutral leaching zinc sulfate solution containing 0.08-2.0mg / L of germanium and with temperature of 60-90 DEG C and pH value of 4.5-5.4 from a wet zinc metallurgical process through a magnetic field generator; 2) keeping the zinc sulfate solution containing germanium in the magnetic field generator for 30-60 min; and 3) conducting liquid-solid separation on the zinc sulfate solution after magnetic field treatment. The germanium in zinc sulfate solution is charged colloid, and in the magnetic field, charged germanium colloid directionally move and agglomerate into large particulate matters, in order to achieve purification of germanium in the zinc sulfate solution. The magnetic field generator uses a permanent magnetic field or electromagnetic field, so that the germanium in zinc sulfate solution in the magnetic field can condense into large particulate matters. The method has the advantages of good germanium removal effect, short work time, no raw material investment, low production costs and low labor intensity.

Description

technical field [0001] The invention relates to a method for purifying germanium in a zinc sulfate solution by applying a magnetic field, belonging to the fields of metallurgy and chemical industry. Background technique [0002] In the hydrometallurgical process, it is necessary to purify and remove germanium in the solution. The existing known methods are the iron hydroxide adsorption method and the zinc powder purification method. The operation time is long, the consumption of zinc powder is high, and the overall production cost is high. . [0003] Therefore, it is necessary to improve the existing method for purifying germanium in zinc sulfate solution, so that no new impurities are introduced in the purification process, the purification method is simple, and the purification rate of germanium is high. Contents of the invention [0004] In order to overcome the above-mentioned deficiencies in the prior art, the present invention provides a method for applying a mag...
