Metal antimony and antimony compounds are widely used in the production of wear-resistant alloys, various flame retardants, enamel, glass, rubber, paint, pigment, ceramics or the like. The main bismuth-containing sulphide mineral is strontium ore (Sb2S3), which is commonly used for flotation recovery. The bismuth oxide mineral is mainly Huanghuahua (Sb204·H20, density 4500~5500kg/m3), which is commonly used for sorting. China's resource reserves and alfalfa production rank first in the world. In 2008, the production of refined 锑 1. 84 x 105t.
Located in Lengshuijiang City, Hunan Province, the tin mine is the largest antimony mine in the world. The ore processed by the North Plant is a sulfide-oxidized mixed strontium ore. The hand-selected one-selection-flotation-re-election process shown in Figure 1 is used. Under the condition that the original ore grade is 3.74%, the grade of tantalum is produced. .48% of the total antimony concentrate, the total recovery of plutonium is 83. 22%.

Plate Heat Exchanger Y Series
Flow field simulation analysis technology, the fluid flow field is equally distributed, the columnar flow in the diversion area, the spiral flow in the heat exchange area, the flow shape is beautiful and there is no dead zone.
Stress analysis technology reduces the internal stress of cold forming, the plate is flat, and there is no deformation after repeated disassembly and assembly.
Lightning-shaped corrugated design technology creates more developed turbulence on the main heat exchange surface and produces a scale-inhibiting effect; the perfect stress relief structure makes the plates flat and free of warping deformation. The unit has many contacts and uniform depth, and has stronger pressure-bearing reliability and repair and maintenance reliability.
Corrugated arc point support technology has excellent anti-deformation and rebound capabilities, improves support strength and reduces internal stress in the plate; it can effectively avoid gaps, retention and deposition of debris.
The unique four-corner auxiliary automatic alignment and positioning technology makes plate assembly more accurate, greatly reduces assembly errors, and makes assembly and maintenance fast and convenient.
The classic five-point plate positioning technology makes the plate assembly more accurate and compensates for the thermal expansion of the plate during PHE operation.
S(mart)-foil detachable plate positioning card technology for large plates, the positioning mechanism has high strength and no deformation in positioning, making the plate more flexible in the guide rod movement and more accurate in positioning
