USING PLANTS FOR GREENING OF TAILING PONDS OF IRON ORE COMBINES OF KRYVYI RIH AREA
(2018)The tailing ponds of the iron ore-dressing combines occupy thousands of hectares in Kryvyi Rih area and create a serious ecologic problem in this region. If the surface of the tailing ponds dries up, it leads to dust ... -
BIOAVAILABILITY OF ELEMENTS FOR EFFECTIVE PHYTOREMEDIATION AND PHYTOMINING: THE ROLE OF RHIZOSPHERE PROCESSES
(2018)The success of phytoremediation (especially phytoextraction) and phytomining depends heavily on the bioavailability of target elements, which, among others, is a function of soil mineral phases, soil organic ... -
THE PCA OF PHYTOMINING: PRINCIPLES, CHALLENGES AND ADVANCES
(2018)There is a number of commercially valuable elements whose concentration in the crust of the earth is too low for an economic mining with traditional approaches. However, phytotechnologies which take advantage ... -
THE GERMANIUM EXTRACTION FROM TECHNOGENIC RAW MATERIALS BY MICROBIOLOGICAL METHODS
(2018)The results have practical significance and can be the basis for developing a unified biotechnological method of technogenic waste processing with a purpose of their sterilization and detoxification with ... -
LEACHING OF SYNTHETIC GaAs- AND INDIUM-BEARING SPHALERITE ORE WITH HELP OF “REICHE ZECHE” MINE WATER
(2018)The main goal of the experiment was to leach minerals using microbes. To accomplish this goal, the course dealt with the acquisition of adequate bacteria, by taking water samples in the underground mine ... -
MICROBIAL CHARACTERIZATION OF ABANDONED MINING AREA OF SIDI KAMBER NORTH-EAST OF ALGERI
(2018)The ecological importance of soil bacteria is not limited to their number or biomass, although these parameters contribute greatly. Indeed, their main asset lies in their great genetic and functional ... -
AMPHIPHILIC SIDEROPHORE MARINOBACTIN FOR FROTH FLOTATION PROCESS
(2018)The consumption of metallic raw materials increased in the last years. The coverage of demand is getting more difficult, because both primary and secondary raw materials become more and more complex. ... -
TEST OF MICROBIAL TRANSFORMATION OF FLOTATION TAILINGS TO CONSTRUCTION MATERIAL
(2018)The use and recycling of secondary raw materials increases resource efficiency. An interesting option would be the use of flotation tailings in the production of building materials. One of challenges is the ... -
SIDEROPHORES FOR SELECTIVE SOLID PHASE EXTRACTION OF STRATEGIC ELEMENTS
(2018)All over the world, industrial mining is leaving contaminated areas and dumps that, although being full of valuable metals, have high concentrations of toxic heavy metals that pollute the environment. The ... -
BBS/BBF ENCAPSULATED MICROORGANISMS TECHNOLOGY FOR SOLID INOCULATION, THE NEXT STEP TO NOT USE WATER IN BIOLEACHING PROCESSES WITH HIGH PERFORMANCE
(2018)Industrial hydrometallurgical processes using copper oxides and mixed oxide/sulfide exhibit high concentrations of several ions in their raffinates that hinder the treatment of copper ores with microorganisms because ... -
A NEW “FERROVUM” SPECIES IN A SCHWERTMANNITE-PRODUCING PLANT FOR MINE WATER TREATMENT
(2018)Mining activities for metals or coal often result in the development of acid mine drainage due to the oxidation of sulfidic minerals which get exposed to oxygen. The acidic mine waters are characterized by low pH, high ... -
INNOVATIVE ECO-EFFICIENT BIOHYDROMETALLURGICAL PROCESSES FOR THE RECOVERY OF STRATEGIC AND RARE METALS FROM PRIMARY AND SECONDARY RESOURCES
(2018)The conventional pyrometallurgical route for winning of metals is increasingly confronted with a number of challenges which include the necessity to exploit more complex and deeper deposits, arsenic ...
