For manufacturers of useful mineral ore many kinds of cross-containing complex, uneven fabric inlay ore particle size, different height and minerals can be optional grinding difference and large production costs, low resource utilization and higher product hetero series Technical difficulties, research and development of a number of key mineral processing technologies:
1, can be solved similar floating multi-metal sulfide minerals separation between the technical problems, indium zinc concentrate grade increased from 45.21% to 47.50%, zinc from the actual recovery rate 56.94% to 74.36%.
2. The new three-phase composite spiral chute with independent intellectual property rights is used in the tin- mineral circuit to increase the total tin recovery by 3%.
3. In the fine-grain flotation of cassiterite, the new high-efficiency floating tin combination agent BY-5 and BY-9 were combined and synthesized with P86, so that the recovery rate of tin operation was increased from 30% to 65%.
4. Developed and applied new combination equipment and technology such as high-frequency vibration fine screen, cone cone concentrator and numerical control dosing machine, which greatly simplified the beneficiation process. The ore dressing cost decreased from 126.78 yuan/ton of raw ore in 1996 to 2000. 71.69 yuan / ton of raw ore. On average, the company increases profits and taxes by more than 70 million yuan per year.
