Development of isolation technology in preparation of the heap leaching fields

The usage of cyanide solutions in technology heap leaching causes, both direct and indirect effect on the environmental components. Existing methods of heap leaching fields isolation do not provide the necessary degree of decreasing of infiltration processes. One of the main reasons is the usage of sutural technology with using geosynthetics are characterized by a number of  disadvantages.

LIGNIN SLUDGE APPLICATION FOR FOREST LAND RECLAMATION: FEASIBILITY ASSESSMENT

The article analyses waste generation of pulp and paper industry in North-Western Russia. The environmental impact of waste storage facilities of the pulp and paper mill was assessed, the need for utilization of lignin sludge was justified. In North-Western Russia, 1.21 million hectares of disturbed areas are in need for reclamation; they are abandoned quarries and lands alienated for pipeline and road construction. The suitability of lignin sludge for preparation of artificial fertile soils for reclamation purposes is estimated. For this purpose, experiments were carried out to create an artificial mixture with different ratios of lignin sludge and soil, to detect the maldevelopment of several plant species grown on various compositions of lignin sludge and soils. It was revealed that lignin sludge as an organic additive to soils is not toxic to vegetation and living organisms, allowing improving fertility of artificial soils.

Assessment of widespread air pollution in the megacity using geographic information systems

Approaches for assessing atmospheric conditions in megacities are proposed using an example of St. Petersburg. An article provides results of field observations on atmospheric air quality conducted with a mobile laboratory of Saint-Petersburg Mining University. Temporal distribution was analysed for concentrations of key pollutants: oxides of nitrogen, ammonia, and carbon; sulphur dioxide; hydrogen sulphide; methane; total hydrocarbons. The given framework for interpreting the data on atmospheric monitoring exploits spatial distribution of pollutant concentrations. The proposed ways for solving the problem of atmospheric pollution in certain megacity districts are based on geographic information systems allowing modelling widespread air contamination.

Creation of a system for industrial environmental monitoring in hydrocarbon producing and transporting companies оf Western Siberia

The paper provides an assessment of environmental impact made by the companies producing and transporting hydrocarbons in Western Siberia. Dynamics of perennial observations over the environment components in the area where hydrocarbon producing and transporting companies operate have been analyzed and justifications provided for a need in the optimal system for environmental air monitoring at the facilities under examination. Dispersion of air pollutants has been simulated using a licensed software ECOLOG (version 3.00), developed by “INTEGRAL” scientific production association. Based on simulation results the list of priority pollutants has been compiled. A method has been developed to determine the quantity of and optimal locations for fixed environmental moni- toring stations with account of emission parameters, and approaches have been proposed to creation of a system for operational environmental monitoring based on geoinformation software.

Two-stage cleaning technology water out from oil

Existing methods of water treatment do not provide the required quality of water injected into formation. Everywhere in the fields is observed gradual effect ions reduce oil output. The reasons can be a lot of both technological and geological. One of the main- is injected is not enough pure water, which causes mudding pores, channels and  cracks.

The improvement of the wastewater treatment system at the apatite-nepheline factory n 2

Joint Stock Company «Apatit» is the world’s largest producer  of phosphate raw materials  for the production of mineral fertilizers. The processing of ore and obtaining of apatite and nepheline concentrates are carried out at the ore treatment factory   ANOF-2. Nowadays there is an acute problem of additional wastewater treatment in concert with the presence of nitrites, fluorides, phosphates, aluminum and molybdenum in flows the concentrations of which exceed the established  standards. Using the fine cleaning filters, the filter material of which is made of synthetic fibers, the quantity of waste substances dropped into the water can be reduced. The using of such filter system will allow decreasing the damage  to the  environment  and reducing the  enterprise payouts for the discharge of pollutants.
