The added rare metal resources are limited, and most of the rare metal is a scattered metal without independent mineral resources and exists along with other mineral resources.
Rhenium is silver white metal or grey to black powder; melting Point3180 deg.C, boiling point 5627 deg.C, and relative density 20.53. Rhenium metal is very hard, wear resistant and corrosion resistant. The surface is the same as platinum, and pure rhenium is soft and has good mechanical properties. Dissolved in dilute nitric acid or hydrogen peroxide solution. Insoluble in hydrochloric acid and hydrofluoric acid. At high temperature, combine with sulfur vapor to form rhenium sulfide ReS2. Does not react with hydrogen and nitrogen, but can absorb H2. Valency is 3, 4, 6 and 7. Can be oxidized to a very stable rhenium heptoxide Re2O7This is a particular property of rhenium. The rhenium supply is 80% from the extraction of the roasted soot collection from mining the rhenium-containing minerals, and 20% from the recycling of secondary resources. At present, the recovery method of metal rhenium mainly adopts electrochemical dissolution, high-temperature oxidation and other methods, rhenium-containing alloy processing powder is oxidized at high temperature, sublimed rhenium oxide is collected, and the recovery rate of rhenium depends on the granularity of the alloy powder.
