Tungsten Slime Recycle – Tabling Method

Tungsten ore is fragile, during beneficiation process, tungsten slime is easily formed. So tungsten tailings still contain many effective tungsten metal elements. According to statistics, tungsten metal in slime usually accounts for 11%~14% of original ore. 

Therefore, tungsten slime recycle can improve resource application rate and lower cost. So tungsten slime is often dealt with separate process.

Tabling method is a tungsten slime processing method in early times in China. It uses single table to process concentrated tungsten slime, the main process is sieving. To promote grade of concentrate recycled from tungsten slime, many mines will sieve it for several times. However, the maximum recycle rate is only 35% and can not be improved any more. for tungsten slime less than 37um, it is too fine for tabling.

Although there are many shortcomings of tabling method, we can not abandon it completely. In those years when technology were backward, the simple and stable recycle method was mainly applied by enterprises. Although the recycle rate is only 35%, 27%~35% are stable. Furthermore, progress of any method is made through practice, from simple to complex. Tabling method is outdated today, but has indelible historic impact.
