Tungsten Tin Ore Dressing Guide
Tungsten tin ore is a brittle mineral, which is extremely easy to be milled and polished during mineral processing, causing inconvenience to mineral processing.
Some scholars have proposed a method of mineral processing for tungsten tin ores. The content of Sn in the mineral materials is 0.083 to 0.32% and the content of WO3 is 0.035 ~ 0.46%. The steps and the pharmaceutical system are as follows:
(1) The tungsten tin minerals are removed to some monomers and the jigging branch separation technology is used to separate the minerals into coarse heavy minerals and fine grain aggregates, and then the coarse and fine grain aggregate minerals are reselected.
(2) Coarse and heavy minerals are selected by spiral chute, and the coarse concentrate and spiral chute tailings are obtained, and the spiral chute coarse concentrate rocking bed is selected. The coarse tungsten and tin concentrate 1, the rocking bed middle mine 1 and the rocking tailings tailings 1 are obtained.
(3) The fine aggregate mineral is recycled by shaking table and coarse and fine process. Tungsten tin concentrate 2, rocking bed middling 2 and shaking table tailings 2 are obtained.
(4) The spiral chute tailings, the rocking bed middling 1 and the rocking bed tailings 1 and the shaking table middling 2 are combined to regrinding, and the tungsten tin coarse concentrate 3 is obtained.
(5) Tungsten tin coarse concentrate 1, tungsten tin coarse concentrate 2 and tungsten tin concentrate 3 are combined, the sulphuric acid solution of 1000 ~ 2000g/t with mass concentration of 5%, 100 ~ 300g/t of copper sulfate solution with mass concentration, 5% of Ding Ji xanthate solution of mass concentration 1% and 30 to 50g/t of 2# oil raw liquid are used to remove sulfide ore and obtain tungsten tin mixture.
(6) Tungsten tin mixed concentrate was selected under the condition of magnetic field strength 10000 ~ 13500Gs wet strong magnetic separation. Tungsten tin separation was selected under the condition of 8000 ~ 10000Gs wet strong magnetic separation, and tungsten concentrate and tin concentrate were obtained respectively.
