[Chemical composition] The composition is relatively fixed, containing a small amount of As, Pb, Ag, Cu and Fe, and most of the elements are mechanically mixed.
[crystal structure] orthorhombic system 
a 0 =1.120 nm, b 0 =1.128 nm, c 0 =0.383 nm; Z=4. 
Figure L-12 Crystal structure of stibnite
(quoted from Pan Zhaoyu et al., 1993)
The crystal structure has a chain structure (Fig. L-12), and the chain is closely connected by S and Sb, and these chains are parallel to the c-axis. The distance between S and Sb in the chain is about 0.32 nm. The bond force is weak, so that the symmetry is shown along this direction {010}, and the crystal form extends along the direction of the chain in the structure, and is columnar parallel to the c-axis.

(quoted from Pan Zhaoyu et al., 1993)
 oblique square column: m{110}, n{210}; parallel double-sided: b010}; oblique square double cone: s{111}, p{331}, t{341}
[Form] The single crystal is columnar or needle-shaped, and the cylinder has obvious longitudinal stripes (Fig. L-13). Larger crystals tend to show curvature. The aggregates are often radial or densely granulated (Figure L-14).
Figure L-14 stibnite cluster
[Physical properties] steel gray or gray lead, surface often blue Qiang color; black streak; crystals often with dark blue Qiang color; metallic luster; opaque. Cleavage parallel {010} complete. The cleavage plane often has a horizontal polycrystalline double crystal grain. Hardness 2. The relative density is 4.6. Crisp.
[genesis and production] is mainly produced in low-temperature hydrothermal deposits, and is symbiotic with cinnabar, quartz , fluorite , barite and calcite .
China's Hunan Xinhua tin mine is the world's most famous and largest source of stibnite.
[Identification features] lead gray, columnar crystal form, longitudinal stripes on the cylinder surface (poly-grain), horizontal stripes on the cleavage surface (polycrystalline twin crystal). For the fine-grained block, the KOH is dropped thereon, and immediately appears yellow, and then turns into an orange-red color, thereby distinguishing it from a similar stibnite .
[Main use] It is an important ore mineral of bismuth. The crystals are large or beautiful and can be highly ornamental and collectible.
Description
Vibrating Conveyors consist of vibration motor,trough,vibration damper,support base and other accessories.it offers a simple and efficient means to meter and convey dry bulk material.Two highly efficient, externally mounted vibrators provide quiet, linear motion and make bulk material moving forward smoothly. There are no dead angle, bearings or seals which can degrade material, leak or require maintenance.These open or enclosed units will handle nearly any material, regardless of size and bulk density in a reliable and economical manner.
The vibrating conveyor can be designed for screening,drying or cooling usage ,by adding the electricity weighing module,the machine can have function of precise feeding.
Feature
* Simple structure and easy for maintenance
* Long service life and no vulnerable part
* Low noise and large capacity
* Low power consumption
* Up to 8 meters long
Application
The machine is available in the industries such as metallurgy, mining, pharmacy, food, chemical, metal powder and nonmetal material etc.
Our machines have an automatic 12 months guarantee against faulty material and workmanship valid from the date of dispatch in China or date of arrival at foreign border.
If any problem of the machine under instruction within one year,we are responsible for replacement incuding delivery fee and maintenance.
Lifelong service is offered with cost charge after one year.
