Pyro-metallurgical metals refining, starting from poly-metallic ores is an energy-intensive and slow process. Usually, the production in Kazakhstan results in lead as the main product, also extracting other valuable metals as side products – including gold, silver, zinc. Considering the large flow rates of the processed materials, and the high monetary values of the side products, it is...
Strategic direction in the development of metallurgy is to increase labor productivity, the integrated use of raw materials, the extraction of valuable components and the improvement of product quality. One of the main steps to achieve the objectives of the lead production is the processing of lead-containing industrial products and additional recovery of valuable components. Improving this...

Обладая хорошими физико-механическими показателями, отвальные породы могут...
Global environmental problems of climate change as a result of anthropogenic impact on nature are firmly among the most debated issues at the international level. An increase in the concentration of greenhouse gases in the atmosphere leading to negative consequences has led to the need to develop new products and production methods characterized by lower СО2 emissions than traditional...
The basin of lake Khubsugul has not yet been affected by human influence (75% of endemics in ecosystem) and can serve to recreate and decoding of the model of the standard' nature system.
A comprehensive study of ecological functioning features of the soils, formed on outputs of phosphorites' layers of Ongolignur deposit of Khubsugul phosphorite basin of Baikal rift zone was conducted. It was...
The aim of research is to carry out the assessment of pyrogenic load and vegetation recovery dynamics after the fire event in 2016 within the drained bog site in Gavrilovka River basin. Specifically, the objectives of this study were to: 1) perform a retrospective analysis of the water-thermal regime according to monitoring data on the nearby site 2) estimate zone of contamination by...
The commissioning of a hot water boiler house at ZAO “Sawmill 25” was another major step in increasing of efficiency of the integrated use of wood raw in the enterprise. It required efficiency assessment of burning bark and wood fuel in the combustion chambers of PR 8000 boilers.
For this purpose, the comprehensive energy audit of boiler house equipment was carried out, the biofuel mixture as...
The North-West of Russia possesses huge wood resources reserves, therefore the issues of the most efficient use of wood biomass are relevant for this region. The implication of wood biofuels into fuel and energy budget provides an opportunity to reduce the negative impact of power industry facilities on the environment and preserve the potential of non-renewable fuels for future generations....
Изучение химико-биологических основ взаимоотношений между насекомыми и патогенными организмами является актуальным вопросом в области экологической химии и представляет интерес для разработки экологически приемлемых методов контроля численности насекомых-вредителей.
