LOSS OF SILICON FROM COPPER ENRICHMENT FACTORY WASTE USING AMMONIUM FLUORIDE
Keywords:
waste, oxide compounds of iron, silicon dioxide in an ammorphic state, sublimation cremation, ammonium fluorite, water solution of ammonia, ammonium hexaphthorsilicate, magnetic sorting, selective melting, silicified residue.Abstract
Waste storage sections and waste in the otvallar under JSC” olmalık KMK " are now considered reserves for the extraction of non-ferrous and rare metals. To date, the landfills contain a total of about 1,750,000 tons of waste, mainly generated by the flotation enrichment of copper. The content of copper in this waste is 0.17%. In addition to copper, the following metals are present: Au, Ag, Pb, Zn, s, Fe, SO2, Al2O3, etc. Therefore, the solution to the problem of waste recycling for the extraction of these raw materials has been very important in recent times.
