As the development of reforming and opening, our beneficiation technology has undergone enormous changes, which has gone beyond the international level in the technology and quality. Commonly used ore beneficiation equipments include: crusher, ball mill, screening & classification equipment, magnetic separator, flotation machine, dryer, etc. The development of ore beatification equipment and technology is synchronization, the process is dominant, the device is the foundation. Hongxing ore dressing process include magnetic separation process, flotation process, lead and zinc mineral process, etc. Each process has different operating processes depending on the raw materials.
The main technical and economic indicators of Hongxing lead and zinc ore dressing process have reached the world advanced level. Poly-metallic sulfide ore flotation process has made significant progress; the new technology of high basicity flotation and mixed concentrate asynchronous priority flotation has been successfully applied in production; more than 40 percent of lead and zinc ore dressing use no-cyanide process; oxidation...
