Obogashchenie Rud

The first article (the authors: V.F. Baranov, I.Sh. Sataev) is an overview of various ore-preparation circuits design and implementation practices at foreign and Russian concentrating plants processing porphyry copper ores. Special attention is given to the two competitive methods: ore semiautogenous grinding and press-roll crushing.

The articles of the section “Processing Technology” are dedicated to Namibian offshore phosphorites material composition and dressability studies (the authors – V. I. Beloborodov, et al.,) and a redox alternative of apatite-nepheline ore thermochemical processing method of Prof. O.N. Tikhomirov (the authors – V.M. Sizyakov, A.K. Orlov).

The article by А.М. Vasilyev is dedicated to the basic issue of the gravity concentration, covering all formulas for ball-shaped particles free-fall final velocity calculation, earlier derived by different authors, as well as the calculations results by these formulas. The article may be recommended as a reference material.

The article by E.А. Khopunov considers the theoretical evidence for discussion of loading factors in selective disintegration of ores. The article continues the subject raised in the author’s publications in the previous issues of the journal. The total series of articles on various aspects of selective disintegration of ores is dedicated to the memory of V.I. Revnivtsev, who in his research work devoted much attention to this question. In March of 2011 a seminar was held at the “Mekhanobr” dedicated to the 80th anniversary of V.I. Revnivtsev, the director of the “Mekhanobr” Institute in 1976-1989. The current issue of the journal includes a publication on this event.

The section “Equipment” presents a new rotary sample divider, developed and produced by “Mekhanobr-Tekhnika” Research-and-Engineering Corporation, designed for samples preparation for analytical and processing studies (the article by А.V. Bortnikov, et al.). The device has a 100-liter sample receptacle and is intended for 20-25 mm size material. In the article by А.Ye. Pelevin, specialties of a hydraulic vibratory screen separation characteristic are considered. The difference between actual screen separation characteristic and the conventional separation characteristic is shown, and the factors causing this difference are analyzed.

In the section “Design Work”, the article by А.N. Smirnov considers the main technical concepts for the ОАО Aleksandrinskaya Mining Company concentrating plant rehabilitation project, planning the plant capacity increase by the factor of two. The project has been developed owing to the change in the plant’s raw materials source.
