Recycle Process of Tungsten Tin Ore

Tungsten tin ore is a brittle mineral. It is very easy to grind powder in the process of mineral processing, and the fine grain tungsten Tin Mineral Reseparation is difficult to be recycled. Therefore, it is very important to discuss the recycley process of tungsten ore. A few successful cases of tungsten tin mine recycley are listed for your reference.

The main metal minerals in a tungsten tin ore are wolframite, a small amount of cassiterite, scheelite, tungsten, magnetite, hematite, limonite, and a very small amount of pyrite and chalcopyrite. Gangue minerals are mainly quartz and muscovite, followed by feldspar, and a small amount of fluorite, calcite, tourmaline, biotite and so on. The granularity of the wolframite in the ore is coarser. Guan Tong adopted gravity magnetic combined process. First, tungsten tin crude concentrate was obtained by gravity separation and tungsten tin was separated by magnetic separation. When the grade of raw ore is 0.40% WO₃ and 0.12%Sn, the grade of tungsten concentrate is 65.03% WO₃, the recycley rate is 79.74%, the grade of tin concentrate is 39.32%Sn, and the recycley rate is 53.30%.

According to the characteristics of a polymetallic ore in Hunan, Lin is used to float sulfide ore in advance, float sulphur tailings at normal temperature floating scheelite, and to produce qualified Scheelite Concentrate by acid dipping dephosphorization by Scheelite Flotation. For the raw ore containing 0.617% WO₃ and 0.043%Sn, the tungsten concentrate has a grade of 65.65% WO₃ , the recycley rate is 85.09%, the tin grade is 28.20%Sn, the recycley rate is 25.95%, and all the scheelite and cassiterite are effectively recycleed.

A tungsten tin mine in Yunnan contains tungsten 0.323% WO₃ and tin 0.140%Sn. On the basis of ore process mineralogy and experimental research, Li Wei adopted a process of grinding to -0.5mm, coarse selection of rocking bed, mixed concentrate desulphurization, iron removal and flotation separation of tungsten tin. The yield of tungsten concentrate was 0.31%, tungsten grade was 71.06% WO₃, tungsten recycley rate was 67.69%, tin 0.56%Sn, tin concentrate yield 0.12%, tin grade 58.18%Sn, tin recycley 50.94%, containing tungsten 3.80%, tin rich medium mineral rate 0.21%, tin grade 4.22%Sn, tin recycley rate of 6.87%, containing tungsten 2.69% WO₃, comprehensive tin recycley rate of 57.81% technical indicators.
