Open Data Verified Data
pyrite is the main sulfur-containing mineral in pyrite ores. Often containing cobalt, nickel, and sometimes copper, gold and silver. Equiaxed crystal system, the crystal is often cubic or pentameric dodecahedron, aggregation is often dense Block, granular or impregnated. The color is light brass or golden yellow, the stripe is green black or black, the metallic luster, brittle, differential fracture, hardness 6~6.5, density 4.9~5.2g/cm3. With weak conductivity, insoluble in water and dilute hydrochloric acid, soluble in nitric acid and sulfur precipitation. When burned on a fire, a blue flame is produced and a pungent sulfur dioxide odor is emitted. Pyrite is the most widely distributed sulfide in the crust, can be formed in a variety of geological processes I in limestone, volcanic rocks and coal beds can be formed separately deposits; Also often with copper, lead, zinc and other non-ferrous metals symbiotic, the formation of multi-metal pyrite bed.

硫精矿 - Preparation Method
Open Data Verified Data
most of the small and medium-sized iron and sulfur mines use underground mining method, and the main mining method is the sublevel caving method. Open-pit mining method is used for a small number of large mines with shallow ore deposits. The general process flow of pit mining and the general process flow of open mining are the same as those of the_phosphorite elbow. Mineral processing methods mainly include flotation, gravity separation and magnetic separation. The general beneficiation process flow is the same as that of "phosphate rock". For single pyrite, multi-metal pyrite and less carbonaceous coal-series pyrite, the grinding-classification-flotation process is generally used; for the coal-series pyrite containing more carbonaceous material and clay, the gravity separation-flotation or the flotation-re-selection combined process is adopted.

硫精矿 - Use
Open Data Verified Data
More than 85% of pyrite is used to produce sulfuric acid, followed by sulfur extraction. Pyrite when associated with copper, lead, zinc, silver, gold, cobalt, nickel and other elements reached a certain content can be comprehensive recycling.

硫精矿 - Safety
Open Data Verified Data
toxicity and protection: in the process of underground mining of pyrite, ventilation and dust management must be strengthened, and the concentration of SO2, CO, H2S and other harmful gases in the mining site must be kept at any time, and pay attention to the discovery of various signs of spontaneous combustion of ore fire, in order to prevent poisoning and fire.
