Publikováno v: Russian Metallurgy (Metally). 2020:507-516

The results of studying the reducing roasting of the high-iron (65% Fe2O3) niobium–rare earth ore of the Chuktukon deposit with the production of high-phosphorous cast iron and niobium–rare earth slag are discussed. The optimum reducing roasting

Genesis, Features of Mineral Composition, and Problems of the Development of Rare Metal–Titanium Placers in the West Siberian Megaprovince

Autor: D. S. Klyucharev, E. N. Levchenko, A. V. Lalomov

Publikováno v: Lithology and Mineral Resources. 55:139-151

The coastal-marine rare metal–titanium placers of the West Siberian megaprovince were formed in a relatively short Eocene–Late Oligocene interval. A similar formation mechanism and commonality of primary sources of ore matter were responsible for

Autor: V. A. Kobelev, L. A. Smirnov, S. A. Spirin, E. N. Levchenko, V. A. Rovnushkin, O. G. Reznitskikh

Publikováno v: Theoretical Foundations of Chemical Engineering. 53:899-907

Magnesium—strontium-containing limestones are overburden and lie together with celestite ore, the extraction of which is economically justified under their conditions of use. The results of determination of mineralogical composition of limestone, s

Mineral assemblages of titanium-zirconium sands at the Central deposit, the east European platform

Autor: V. V. Barsegyan, I. A. Chizhova, E. N. Levchenko, E. A. Andrianova, V. T. Dubinchuk, A. I. Stekhin, N. G. Patyk-Kara, A. A. Bochneva

Publikováno v: Geology of Ore Deposits. 50:218-239

The study of mineral assemblages at the Central deposit allowed us to substantially refine the evolutionary model of the deposit and reveal the two main factors that control the variability of its mineralic space: (1) heterogeneity of the ore layer,
