The highly efficient permanent magnet technology developed by Hubei Shengrong Environmental Protection & Energy Technology Co., Ltd. has recently obtained two international invention patents.

The “method for axially sorting the inner surface of the permanent magnet arc groove” and “axial separation method and equipment for the eccentric inner surface of the permanent magnet cylinder” developed by the company are the core components of the high-performance permanent magnet integrated sorting technology. section. High-performance permanent magnet integrated sorting technology utilizes the difference in the susceptibility of the material composition ratio, and carries out a permanent magnet and physical comprehensive sorting. The material composition has a relatively larger magnetic susceptibility (high magnetic portion) and a relatively small magnetic susceptibility. Parts (low magnetic or non-magnetic parts) are separated and the two parts are separately disposed or utilized. This technology uses a new type of permanent magnetic material independently developed by the special magnetic circuit process to produce a high gradient magnetic field, can be a variety of (especially fine-grained) weakly magnetic substances for physical selective separation, not only from the low grade High-grade concentrates are selected from the tailings, and higher-grade concentrates can be separated from tailings (slags).

The application of this technology can significantly increase the yield and recovery rate of the target products (such as manganese concentrates, iron concentrates, etc.), and reduce the loss of heavy metals in tailings slag. The new permanent magnet magnetic system layout adopts a closed type magnetic system composed of a self-developed permanent magnetic material, which has a high magnetic force and can be widely applied to include waste catalysts, manganese tailings slag, iron tailing slag, and hematite, brown Iron ore, copper tailings slag, aluminum slag (red mud), tailings slag, nickel molybdenum tailings slag processing and other fields.
