| Abstract: |
| Certain mineral processing tailings in Hunan contains Sn 0.15%, and tin mainly exists in the form of cassiterite. Due to the fine particle size, it was difficult to recover tin from it by single gravity separation or flotation. Due to the difficulty of recovery, this tin resource has been stored in tailings pond for a long time, resulting in resource waste. In order to comprehensively utilize the tin resources, a systematic beneficiation was carried out. Finally, the tin resource was recovered by the combined process of centrifuge desliming-flotation(One roughing, two scavenging and four cleaning). The locked-circuit test index is as follows: tin concentrate contains Sn 16.11% and recovery 69.91%. |
