Abstract

To determine the effectiveness of high-gradient magnetic separation (HGMS) for kaolin clay purification and coal desulfurization in China and to develop suitable technology, a superconducting HGMS facility has been constructed and put into operation. The working separation chamber is 80 mm in diameter and 400 mm in length. The magnet is wound with 0.75-mm and 0.5-mm diameter NbTi superconducting composite. The winding is compact and wax-filled. Tests prove that the magnet can operate at 5 T. Special attention has been paid to design and construction of the magnet cryostat. In the wet benefication mode, there are two separation systems available; one is an upward pumping feeding system and another is downward gravity feeding. The rate of flow and the linear velocity are 0-0.5 L/s and 0-100 cm/s, respectively. Preliminary sample test results for kaolin clay purification and coal desulfurization show the feasibility of magnetic separation
