Obogashchenie Rud

The first issue of the journal “Obogashchenie Rud” (2012), besides a new cover, will also attract attention of specialists by its publications. Here are some of them.

The article by G.N. Mashevsky, et al., considers a new approach to controlling the process of sulfide minerals selective flotation separation from pyrite in lime medium, the advantages of process control based on pulp рН controlled by means of molybdenum electrode are proved, comparison is drawn with respect to conventionally applied methods of рН-metry and conductometry.
The article by V.V. Zuev continues the series of the author's publications dedicated to application of the modified system of energy coefficients, developed by academician Fersman, to justification of the core-electron concept explaining structure and properties of minerals. The establishment of the fundamental regularity, consisting in that core-electron energy in minerals exceeds binding electron energy by an order of magnitude greater, permitted to appreciably simplify the formula of minerals core-electron interaction energy estimation.

The article by V.I. Kibirev, et al., considers the essentials of the project of deep thickening of tailings with thickened tailings hydraulic transport and disposal system, successfully introduced at the Nurkazgan Concentrator of “Karagandatsvetmet” Operation, “Kazakhmus Corporation” (Republic of Kazakhstan). It is shown, that application of high-throughput thickening equipment provided for decrease in disposed tailings slurry quantity by the factor of three and allowed to commission the concentrating plant ahead of schedule.

The article by Yu.S. Golovina, et al., is dedicated to the 30th anniversary of the Talnakh Concentrator operation, being a part of the “Norilsk Nickel” Mine-and-Mill Complex transpolar operations. The main milestones of the Talnakh Concentrator upgrade and technical re-equipment Project realization with the capacity increase to 16 million tons per year by total ores quantity are presented. New engineering and technical solutions, taken as a basis for the next Project design stage, started in 2011, with the view to provide for construction and commissioning of the rehabilitated Plant, are considered.
