Problems solved by technology

However, the effect of the existing beneficiation process is not ideal when it is used for the beneficiation of colloidal tin ore
[0005] The molecular formula and structure of colloidal tin have not yet been fully clarified. Because tin-containing minerals are wrapped in a layer of jelly, it is called colloidal tin. It is insoluble in acid and lighter than water. Therefore, in the re-election process, often Run away with the water, resulting in a low recovery rate of beneficiation
The low recovery rate of colloidal tin beneficiation has always been a worldwide problem, and there is no better way to solve it

Embodiment 1

[0025] A method for improving the beneficiation recovery rate of colloidal tin ore body, the concrete steps are:

[0026] 1) After the cassiterite and colloidal cassiterite are ground and mixed according to a certain ratio, the cassiterite is divided into two parts, which are respectively selected into the IV-1 ore body and the VI-1 ore body of the Pengshan Tin Mine in Jiangxi, and the IV-1 ore The mass percentage of cassiterite Sn in the body is 0.6% to 0.8%, the mass percentage of cassiterite Sn in the Ⅵ-1 ore body is 0.6% to 0.75%, and the colloidal cassiterite is selected from the Ⅶ- 1 Ore body, wherein the mass percentage of Sn is 40% to 45%, SnO 2 The mass percentage is 55% to 60%. The mixing ratio is mixed uniformly according to the mass ratio IV-1:VI-1:VII-1=1:1:1. After mixing, the mixed powder is sieved, and then the sifted powder is soaked in a mixed acid of hydrochloric acid and hydrofluoric acid to remove impurities, and after the removal of impurities is comple...

Embodiment 2

[0032] A method for improving the beneficiation recovery rate of colloidal tin ore body, the concrete steps are:

[0033] 1) After the cassiterite and colloidal cassiterite are ground and mixed according to a certain ratio, the cassiterite is divided into two parts, which are respectively selected into the IV-1 ore body and the VI-1 ore body of the Pengshan Tin Mine in Jiangxi, and the IV-1 ore The mass percentage of cassiterite Sn in the body is 0.6% to 0.8%, the mass percentage of cassiterite Sn in the Ⅵ-1 ore body is 0.6% to 0.75%, and the colloidal cassiterite is selected from the Ⅶ- 1 Ore body, wherein the mass percentage of Sn is 40% to 45%, SnO 2 The mass percentage is 55% to 60%. The mixing ratio is mixed uniformly according to the mass ratio IV-1:VI-1:VII-1=2:1:1. After mixing, the mixed powder is sieved, and then the sifted powder is soaked in a mixed acid of hydrochloric acid and hydrofluoric acid to remove impurities, and after the removal of impurities is comple...

Embodiment 3

[0039] A method for improving the beneficiation recovery rate of colloidal tin ore body, the concrete steps are:

[0040] 1) After the cassiterite and colloidal cassiterite are ground and mixed according to a certain ratio, the cassiterite is divided into two parts, which are respectively selected into the IV-1 ore body and the VI-1 ore body of the Pengshan Tin Mine in Jiangxi, and the IV-1 ore The mass percentage of cassiterite Sn in the body is 0.6% to 0.8%, the mass percentage of cassiterite Sn in the Ⅵ-1 ore body is 0.6% to 0.75%, and the colloidal cassiterite is selected from the Ⅶ- 1 Ore body, wherein the mass percentage of Sn is 40% to 45%, SnO 2 The mass percentage is 55% to 60%. The mixing ratio is mixed uniformly according to the mass ratio IV-1:VI-1:VII-1=1:2:1.

Abstract

The invention discloses a method of raising a colloidal tin ore dressing recovery percentage. The method specifically comprises the following steps: 1) tinstone and colloidal tinstone are subjected to ore grinding treatment separately and then are mixed according to a certain proportion, mixed powder is screened after the mixing, then screened powder is soaked in mixed acid of hydrochloric acid and hydrofluoric acid for impurity removal, and after the impurity removal is completed, the mixed powder is washed and dried; 2) the mixed powder is subjected to magnetic separation; 3) the mixed powder after the magnetic separation enters a hanging trough type flotator for floatation, during which a NaOH solution or a HCl solution is used to adjust PH of floatation ore pulp to be 3-5, and a collecting agent is added to the floatation ore pulp for preventing colloidal tin from losing; and 4) the mixed powder after the floatation enters a shaking table for gravity separation, and tin concentrate is obtained after the gravity separation. Under the condition that no ore dressing flow is changed, the problem that the colloidal tin ore dressing recovery percentage is low is solved effectively, the economic benefits of an enterprise are improved substantially, and the three rates of ore dressing are raised remarkably.

Description

technical field [0001] The invention belongs to the technical field of beneficiation, in particular to a method for improving the recovery rate of colloidal tin ore body beneficiation. Background technique [0002] Tin has many uses. Pure tin reacts slowly with weak organic acids, so it is often used in the manufacture of tinned sheets, which are used as food packaging materials. Tin can also be used to make coatings for some mechanical parts. Tin can be alloyed with almost all metals, and is widely used in shipbuilding, aviation, chemical industry, atomic energy, medical equipment and other departments; niobium-tin intermetallic compounds can be used as superconducting materials; tin-silver alloys are used as dental metal materials. [0003] There are more than 50 kinds of tin-containing minerals known in nature, and there are about 20 kinds of main tin minerals. There are nine kinds of natural elements and intermetallic compounds in tin minerals, which mainly appear in ...
