Potassium sodium feldspar raw ore is produced from weathered granite or feldspar sand ore, and ore washing is an effective pretreatment step. Mine washing is mainly to remove clay, fine mud and mica and other impurities, through the erosion of water flow, these impurities can be separated from potassium and sodium feldspar. PTMS MAGNETIC SEPARATOR The iron removal process can not only reduce the Fe ₂ O ₃ content in feldspar ore, but also improve the potassium and sodium content in feldspar ore.
Some potassium-sodium feldspar deposits with more clay quality can significantly improve the quality of ore after washing, and reduce the difficulty of subsequent PTMS MAGNETIC SEPARATOR iron removal. The grinding of feldspar is mainly divided into dry grinding and wet grinding. Relatively speaking, the efficiency of wet grinding is higher than that of dry grinding and it is not easy to appear "overgrinding" phenomenon. In order to avoid bringing iron impurities in the grinding process, the grinding process of feldspar ore generally does not use iron medium grinding, mostly using stone wheel rolling, intermittent gravel grinding or porcelain ball grinding.
In the ceramic industry, the quality of feldspar is high. In order to avoid iron pollution, stone wheel rolling or porcelain ball grinding is mostly used; in the glass industry, feldspar processing mostly uses steel rod medium grinding, with high grinding efficiency and uniform particle size, but iron pollution, which leads to low quality of feldspar, and PTMS MAGNETIC SEPARATOR iron removal is required.
