CONTENTS A.I. Kalashnik, A.Yu. D ’yakov GEORADAR RESEARCH OF THE GEOLOGICAL AND STRUCTURAL COMPOSITION OF THE WORKING LEDGE OF THE PIT AIMED AT OPTIMIZATION OF PARAMETERS FOR DBW CARRYING OUT The article is devoted to research of the underground massif of rocks in th e sites of d e e p working ledges of the pit "Zheleznui" of J SC Kovdorsky GOK. Results of g eo ra d a r re s e a rc h e s of the rock massif composing a ledge are given together with visual and telemetric inspection before work and after drilling of explosive wells. An interconnection of structural defects in rocks with their dielectric transmissivity was stated. G eo rad a r s o u n d in g -b a s e d a p p r o a c h e s are propo sed to operative estimation of structural defects into the explosive block of a working ledge of an op en -ca st mine. Keywords: pit, ledge, DBW, georadar sounding, structural fracturing, operative estimation. Authors Anatoly I.

Kasikov ICTREMRM KSC RAS: RESEARCH AND DEVELOPMENT IN CHEMISTRY AND TECHNOLOGY OF COBALT A survey of research carried out by ICTREMRM KSC RAS in the a r e a of chemistry and technology of cobalt is presented. Being a strategic element, cobalt is in an e v e r growing d em an d that stimulates research of Co recovery from different sources. In this work, we introduce s om e results of research in cobalt leaching from lean sulphide copper-nickel ores, metallurgical slags, cobalt concen trates and synthesis residues of nickel carbonyl. The significance of ICTREMRM’ role in development and deployment a hydrochloride solvent extraction technology of cobalt concentrate at Severonikel Combine (Kola MMC) is demonstrated. A new manufacturing s c h em e of cobalt extraction from sulphide nickel-cobalt m a s s of Yuzhuralnikel Combine is p resented and several method s for in-depth processing of se condary cobalt- containing raw materials are described. Information on relevant r e s e a rc h e s in the production of cobalt metal and powders, syn thesis of salts and complex compounds, a s well a s studies on cobalt extraction from sew a g e water with different reag en ts is given. Keywords: ICTREMRM, cobalt concentrate, solvent extraction, isolation, cobalt compounds, raw materials, ore. Author Aleksander G. Kasikov - Ph.D., Corr.
