Diamond producers ranking next after De Beers and ALROSA
The article deals with the second-tier diamond producers, such as Petra Diamonds Limited, Dominion Diamond Corporation, Lucara Diamond, and Mountain Province Diamonds. The authors discuss their production structure and diamond output trends of the latest years showing the most dynamically developing and efficient companies and mines. Today, their share in the world diamond output is already significant. The analysis of development trends and experience of these producers prioritizes the opportunities and areas of boosting the efficiency of diamond mining.
Role of the State in Mining Industry
The trend toward more state engagement in the mining industry has continued on the new forms of state control which are found in Africa and also in Russia, China, India, and other emerging economies. The level of state control is surprisingly high in many metals irrespective of privatizations during the late 1990s and the first decade of the 2000s. State control has increased mostly due to growth of Chinese state controlled mining in China and gradually also abroad. State control of refining is higher than in mining. This is probably due to the higher value added in this sector.
Design features of belt conveyors with spatial track for transporting bulk materials
Abstract: The issues associated with conditions of exploitation of belt conveyors with curved track are examined in the article. Examples of exploitation of such conveyors at mining enterprises are given in the article too. The description of the design features of idlers installed at the horizontal curved sections of a conveyor track is represented. The use of shortened average roller at the carring branch of the belt conveyor is examined too. The substantiation of the necessity of the use of intermediate drives is given.
Conceptual model of the common communication medium for the formation of the talent pipeline in production and science of the RF economy mineral resources sector
The authors discuss the objectives of the formation of the education system new model for the training of future professionals in mining and geology for the Russian knowledge-driven economy. A conceptual model of the common communication medium formed on the basis of the Interuniversity Academic Center of Navigation in Mining Engineering and Geological Disciplines is presented. An MBA MINING curriculum is proposed for the mining sector top and mid-level managers training.
