Soil seed bank is an important component of ecosystem resilience and represents a stock of regeneration potential in many plant assemblages. Soil seed banks can be used to predict the composition of new plant recruitment. Species overcome periods of unfavorable weather conditions by building up a large seed bank. With this strategy, the species diversity is preserved and information on their dynamics and structure is retained. The research on soil seed bank has received wide interest because of its important role in plantation renovation and restoration, biological diversity preservation, vegetation succession and diffusion processes and other aspects. This paper reviews the relationship between soil seed bank and disturbance, geographic factor, vegetation and seed size and is aimed at providing some useful reference for future research.

The authors report experimental research and in situ study of oxidation and ignition factors in opencast mining of fire-hazardous ore. The article makes recommendations on spontaneously flammable ore extraction and storage as well as prevention of endogenous fires and fire protection in sulfide ore stockpiles.

The article describes experimental destruction of kimberlite ore and impact crushers and bases the use of the combined impact crusher DKD-300 at one of the crushing stages within the dry concentration scheme at the Zarnitsa kimberlite pipe projectre.

The authors have designed a stand with a pendulum drop hammer to model the hammer head–impact tool–rock mass interaction. The rock mass is simulated with an adjustable gas–liquid dampener, metal plate and marble block. The comparison analysis includes measured impact pulses in the hammer head and the impact tool, and the influence of the hammer head velocity recovery factors on interaction of the hammer head and impact tool with the dampener and rock block.

The article describes the design of the unique monitoring system for technical state of transportation vehicles and production machines used in mining and construction. The introduction of the system will cut down expenditures due to sudden machine failure, and will increase efficiency and capacity of machines.

The article presents experimental research of the influence exerted by electrochemical polarization on electrode potential, phase composition of surface formations, adsorption of collector and floatability of basic sulfides of gold-bearing ore. It is shown that phase composition of surface formations under different polarization modes affects adsorption of collectors and floatability of minerals.

Based on the nonmechanical energy deposition tests aimed at intensification of destruction and processing of rebellious minerals, it is found that mineral treatment by accelerated electron flow enhances technological performance of mineral processes and is cost-effective: metal extraction grows by 27% and processing performance is enhanced 2.2 times.

In terms of galena, the authors specify construction principles for kinetic “ion” modeling of surface layer composition on grains of sulfide minerals of nonferrous heavy metals during flotation. The physical sense of the models consists in connection of parameters of ions within liquid phase of flotation slurry with relative fractions of mineral grain surface. Commercial tests proved the theoretical concept on formation of sorptive layer of sulfhydryl collectors on the surface of sulfide mineral grains under flotation conditions.

It is possible to forecast efficiency of mechanical activation of loparite concentrate to make it subsequent nitric-acid leaching fast using the X-ray crystal analysis data. It is found that the type of accumulated energy influences the energy of activation and reactivity of loparite. The authors suggest an expression to estimate extraction of rare earth elements in nitric-acid solution versus energy of structural changes caused in loparite by mechanical activation and leaching.

The article focuses on the current situation and problems of the mineral and raw materials base in Russian Federation.
