"STUDY TECHNOGENIC SAND - processing waste Copper ores and identify possible ALLOCATION COPPER AND MOLYBDENUM-CONTAINING FRACTIONS BASED ON THE USE OF TECHNOLOGY EMC
Determination of capacity allocation copper concentrates and molybdenum-containing minerals and quartz from man-made materials - sand, with the help of technology EMC
and other dry methods.
The chemical composition of sand according to the customer includes their potential market value, which for copper is 2 kg / m 1,78 $ / kg ~ 3 $ / t, and accounting molybdenum provided a marginal increment of about 5%. It was assumed that copper and molybdenum are predominantly in the form of sulfides and associated with pyrite FeS2. The survey showed that copper content in the 7 times lower than the balance, and molybdenum - 100. Residual minerals containing copper and molybdenum, not associated with pyrite. Copper is mainly located in the thin non-magnetic fraction, molybdenum and silver - in the ferromagnetic fraction, together with magnetite. Discovered in the heavy fraction increased content of zirconium and rare earth elements, as well as tin, silver and cobalt. Sand containing SiO2 90-95% can not be obtained without the use elektroseparatsii. The optimal scheme of processing methods, dry sand separation.
