| Use | Use 1, for medicine, arsenic and arsenic compounds. 2, arsenic minerals are mainly used to extract arsenic, arsenic acid and arsenic compounds, such as calcium arsenate, sodium arsenate, lead arsenate and so on. In the metallurgical industry for the refining of arsenic alloy; Arsenic-lead alloy in the military industry for the manufacture of warhead, military poisons and pyrotechnic; Arsenic-copper alloy and arsenic-lead alloy used in the manufacture of radar parts and automobiles; in the light industry for the manufacture of milky white glass, decolorizing glass, washing wool, tanning agent and used for wood preservation; In agriculture for pesticides, herbicides, rodenticides and other arsenic containing pesticides; in the pharmaceutical industry can be used as drugs and strong irritant, high-grade realgar and orpiment ore can be directly used for traditional Chinese medicine, the drug name of arsenic products called arsenic. Realgar concentrate powder can be used in the manufacture of fireworks, fireworks and mosquito coils. |
use underground mining, shaft and inclined shaft joint development. The mining method uses the empty field mining method. See "Phosphate Block Rock" for the underground mining process ". The beneficiation method is flotation. In order to make full use of lean ore resources, Hunan Realgar Mine has carried out flotation tests. The beneficiation process includes one-stage grinding (negative 200 is 65%), one-time roughing and one-time sweeping, with concentrate grade above 93.83%.
