40 years Germany has been producing iron ore lepidolite from a tungsten-tin ore with magnetic separation and flotation. The mine only recovered tungsten and tin minerals in the 1920s, while iron-lithium mica was abandoned as tailings. Due to the market demand, the iron-lithium mica concentrate was recovered from the accumulated tailings by magnetic separation method, and then the iron-lithium mica beneficiation workshop was built. In 1945, the plant with a scale of 600 tons/day was built, respectively, using magnetic separation and magnetic separation. The iron-lithium mica concentrate is produced by combining two processes of flotation, and the concentrate grade is 95%-97% iron-lithium mica, and the recovery rate is 50%-70%. There are two types of ore processed, as shown in Table 1, and the production process is shown in Figures 1 and 2.

VM70-15C is specially designed to produce disc brushes. It is equipped with two drilling heads and one tufting head, and is suitable for the production of disc brushes. It can be used to produce flat brushes too when the platform is changed.
