Tin ore leaching bismuth iron trichloride, tin slag available mineral leaching recovered.
The leaching residue component is (%): Sn 3 to 4; Bi 0.3 to 0.5; Pb 2 to 3, As 13 to 15, S 25 to 28, and Te 23 to 35.
Its beneficiation process is shown in Figure 1.

Technical conditions: The flotation operation uses butyl yellow drug as the collector of sulfur- arsenic iron ore, turpentine as the foaming agent, and the flotation slurry is heated to 60 ° C to inhibit tin and antimony, so that it mainly enters the tailings.
Through operations such as coarse floatation, fine floatation and arsenic-free flotation, the ferrite iron ore and high arsenic rich sawing ore are produced, and the flotation tailings are re-elected by two shakers to produce crude tin concentrate and low-lying medium ore. The crude pan concentrate is subjected to arsenic removal flotation to produce high arsenic rich tin ore and low arsenic tin concentrate. The mineral composition of the sorted materials is as follows.

Main equipment: ball mill φ600×2000 mm one; flotation machine; impeller diameter φ300 mm, 3A, 10 sets; 4 mud-slot shaker shakers.
Equal wall thickness motor is much more advanced than normal Downhole Motors. The practice tells that equal wall thickness motor has larger torque, longer service life and better high temperature resistant. Besides, equal wall thickness motor has obvious advantages in deep well, high-density drilling fluid well and small curvature radius horizontal well.
