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. 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...
