Hunan Shizhuyuan Polymetallic Mineral Concentrator
Hunan Shizhuyuan Polymetallic Mineral ConcentratorWolframite has a mud volume of 100 tons/day, a concentration of 24%, a tungsten grade of 1-2%, a tin grade of 0.3, and a fine particle ore of -400 mesh accounting for about 90%. A mixed concentrate with a tungsten grade of 25% and a tin grade of more than 6% can be obtained by adopting a beneficiation process consisting of 26 suspended vibration cone concentrators. The tungsten recovery rate is 45%, the tin recovery rate is 40%, and the annual output is 202 tons of tungsten trioxide, tin metal 36 tons, with an annual output value of more than 2200 million yuan.
Compared with the original process "shaker + flotation", the operating cost of the suspended vibration cone concentrator is only 1/6 of the original process, the tungsten grade is increased by more than 10%, and the fine cassiterite is recovered.
