Description

Technical Field

[0001] The invention belongs to the technical field of fluorite concentrate quality, and specifically relates to a method for improving the quality of fluorite concentrate. Background Art

[0002] A skarn-type polymetallic mine produces fluorite concentrate with a CaF2 grade of 90.34%, a CaCO3 grade of 4.52%, a SiO2 grade of 3.64%, an S grade of 0.04%, and a P grade of 0.03% through flotation. Due to the low CaF2 grade of the concentrate and the high content of impurities such as CaCO3 and SiO2, the fluorite concentrate is currently sold as metallurgical-grade fluorite, and the overall economic benefits are relatively low. The CaF2 grade of the fluorite concentrate is low, and the content of impurities such as CaCO3 and SiO2 is relatively high, resulting in a low grade of the concentrate product. The CaCO3 and SiO2 impurity element minerals in the fluorite concentrate are mostly fine-grained poor conjoined bodies, which makes it difficult to suppress the fluorite flotation process; in addition, the existing flotation tanks cannot be cleaned after use, which affects the cleaning efficiency and reduces the cleaning effect.
