Obogashchenie Rud

The first article in this issue: “Upon ores disintegration selectivity estimation” (the authors: G.D. Krasnov, et al.), in the section “Ore Preparation” in practice continues the discussion of the problem of mineral materials selective disintegration, raised in the theoretical works by E.A. Khopunov, published in the previous issues of the journal. The experiments performed in different apparatuses: ball and rod mills, inertia cone crusher and high-pressure rolls, with disintegrated product particle-size distribution analysis, demonstrate the advantage of the methods with dominant bulk compression mechanism.

The article “All-round chemical-dressing technology for processing of rischorrites” (the authors: Ye.S. Gorbunova, et al.), in the section “Processing Technology” deserves attention owing to the reflected in the title all-round comprehensive solution to a question of the Khibini Mountains high-potassium nepheline-feldspar rocks processing with production of non-chlorine potash fertilizers, alumina and amorphous silica.

The section “Process Theory”, that recently appeared in the journal, is increasingly in demand. The authors of the article “Upon vibration effect on flow of liquid in tray, and associated nonlinear effects” (I.I. Blekhman, et al.), tried to answer the question: is it possible to cause directed flow of liquid upon flat surface by means of vibration? The experiments described in the article showed that only violent vibration produced a small effect through various nonlinear effects. Description of cellular structures formed on vibrating surface of liquid and an attempt of theoretical analysis of this phenomenon are of a certain interest. The aim of the author of the article “Special features of pneumatic mineral dressing methods” (N.F. Merinov) is to attract attention of the specialists to pneumatic mineral dressing methods as most economical. The article presents a detailed comparison of special features of behavior of mineral particles of various density and size with regard to free and hindered falling in water and in air.

The idea, earlier expounded in the article “Loose material classification under vibratory segregation conditions – device, modeling, experiment” (“Obogashchenie Rud” No. 5, 2010), also published in the section “Process Theory”, served as a basis for development of a wedge wire screen model, with its main performance parameters being analyzed in the article “A vibrating sizing screen model (wedge wire screen) study” (the authors: А.V. Bortnikov, et al.), published in this issue of the journal in the section “Equipment”.

The review of the world practice of copper-porphyry ores dressing (the article by I.Sh. Sataev, V.F. Baranov), presenting the new technical developments applied at foreign concentrating plants, may be useful for Russian specialists in the way of operating technologies improvement, new processing solutions development, existing operations upgrade.
