This article talks about the territories of Uzbekistan, which are rich in ore and nonmetallic minerals, lists measures for rational use available mineral raw materials Fergana Valley, particular Namangan region, development on this basis regions construction industry.
In recent years, the industrial use and importance of boron compounds has further increased with the potential application of boron as hydrogen carrier in the form of BH4 in the exploitation of hydrogen as clean energy. Boron compounds can be produced from a variety of boron minerals and boronrich brines. Colemanite (Ca2B6O11.5H2O), ulexite (NaCaB5O6(OH)6.5H2O) and borax (Na2B4O5(OH)4.8H2O) are...
at the present time, flotation is the primary method for copper minerals separation from copper ores. the main copper ores that is extracted in the world is sulphide ore. the sulphide minerals are floated readily by using sulphydryl collectors. in the case of using xanthates , which are among the sulphydryl collectors, used more in the flotation of sulphide minerals of copper, the flotation of ...

The Qatruyeh iron occurrences are located in the eastern edge of the Sanandaj-Sirjan metamorphic zone, southwestern Iran (at 50 Km northeastern of Neyriz), and are hosted by a Late Proterozoic to Early Paleozoic sequence which is dominated by metamorphosed carbonate rocks. The Iron ores occur as layered, massive and disseminated magnetite and in lesser amount as hematite-bearing veins and veinl...
In the course of geological prospecting fulfilled with participation FGBI TsNIGRI within Chayangro ore cluster Dodykhta-Uryakh region in southeastern Baikal-Patom metallogenic province, Dzhalagun lode gold prospect field same name was studied and its economic significance has been proved. It substantiated that is closely similar to typical deposits Bodaibo sense formation phasing, character hyd...
Based on the JK Drop Weight test and principle of selective crushing, a multicomponent complex ore with its component minerals, i.e., pyrrhotite, sphalerite, quartz, was used to explore impact crushing characteristics relationship between minerals. Results show that order resistance is quartz > pyrrhotite sphalerite. The particle-size-distribution characteristic curve products always “sandwi...
