Show more

The wealth of the bowels of Kazakhstan has not yet been exhausted, there are promising areas that are currently insufficiently studied, especially at depth. The reason for the insufficient knowledge of geological structures in depth is the lack of a theoretical basis for geological research and justification for the forecast of prospect for minerals. In this regard, geology faces the question of creating a scientific approach for predicting new prospect areas, especially at depth. Our analysis shows that the princ...

Cyanobacteria are ancient photosynthetic organisms that under certain conditions (high temperature, eutrophication) can grow rapidly and form "cyanobacterial blooms". Very often, these blooms are accompanied by production of cyanotoxins, which in most cases are dangerous to the other organisms. Knowing the producers of cyanotoxins is of utmost importance, especially today when climate change has been shown to increase the frequency of toxic cyanobacterial blooms worldwide. The aim of the present study was to chara...

Organic waste has been discharged into the environment by various industries in a global society. Anaerobic digestion has proven its potential as a waste-to-energy (WTE) technology to produce biogas, which can also replace fossil fuels while accommodating these unwanted wastes. However, there are limitations to anaerobic digestion, such as poor biomethane yield due to limited supply and fluctuations in the composition of the substrates, and an inadequate C/N ratio in the feedstocks. This paper aims to discuss poss...

Nowadays there is a search for alternative motor fuels. In this situation, applied science is actively working on the problem of the search of cheap, high-calorie and environmentally friendly fuel.To solve this problem, the basic technological scheme of processing of real exhaust gases of TPP in a high-octane diesel is developed, and laboratory apparatus (column with cooling tubes) for the synthesis of methanol and dimethyl ether is suggested.The advantage of the developed scheme of reprocessing of real exhaust ga...

CHEMICAL AND BIOLOGICAL TREATMENT OF A DIESEL CONTAMINATED SOIL

(Stef92 Technology, 2011-06-20, Costel Bumbac)

Show more

Organic contaminants such as total pe troleum hydrocarbons, including aliphatic hydrocarbons, polycyclic aromatic hydrocarbon s and BTEX are recognized as one of the predominant pollutants within Romanian contaminated sites. This study presents a set of experiments for the remediation of a soil contaminated accidentally with petroleum products conducted in slurry-type batch systems, designed to establish the best remediation approach. The experime ntal variants consisted in biological remediation (natural attenuat...

The mineralogical and technological study of gold ores and dressing products demonstrate the persistence of both the ores and products of their dressing, especially Floatation concentrates. The gold loss in the tails of Floatation beneficiation are primarily associated with the smallest size fractions less than 20 microns, which make up to 70\% of the total lost gold in the Floatation tails. It is obvious that increasing the extraction of gold by Floatation is directly linked to the development of the technologica...

OPTIMIZING GHORABI IRON ORE GRADE BY GEOGRAPHIC INFORMATION SYSTEM (GIS) FOR USES IN STEELMAKING IN EGYPT

(SGEM Scientific GeoConference, 2009, M. Gojamanov, A. R. Embaby)

Show more

Geographic information systems (GIS) constitute a new powerful technology that can address many of the information needs of decision makers in state and local governments. Therefore this paper represents an attempt to use this technique to optimize Ghorabi iron ore grade for uses in blast furnace as the first step in steel industry in Egypt.
