【 摘 要 】

The potassium feldspar ore in a certain area of Chengde contains K2O 9.82%, Na2O 2.41%, which belongs to the high quality feldspar ore. It cannot be exploited and utilized because of the high iron content. An experimental research was carried out to remove iron from a feldspar ores in this area by the technique of high gradient magnetic separation respectively. The properties of potassium feldspar ore were analyzed, and the technology for iron removal from potash feldspar ore was expounded. The optimum parameters were determined. Finally, the content of Fe2O3in the potash feldspar was reduced from the original 0.88% to 0.082%, significantly reduced the content of Fe2O3. The effect of iron removal was ideal, and the products can meet the requirements of high-grade daily porcelain on feldspar raw materials.
