  • 13.01.14 Value from wastes - research for secondary raw materials
    There are basically two main possibilities for recovery of critical raw materials (CRM) in Hungary:
    1. Mining and processing of ore,- mineral and coal mining tailings, fly ashes and metallurgic process of CRM bearing concentrates.
    Within the frame of this subproject, tailings from Fehérvércsurgó glass sand ; fluorite – polymetallic ore tailing from Pátka and manganese ore tailing from Úrkút are involved. Process engineering technical aspects are  studied using physical (based on magnetic, electric properties or based on different specific gravity), physic-chemical and chemical separation methods.
    2. Recovery of CRM from construction materials of end of lifetime electric and electronic devices produced for industrial and household use.
    WEEE, like scrap notebooks, mobile phones, display panels(PDP, LCD, LED-LCD) and PCB’s Critical elements  contain high concentrations of Sb, Be, Co, F, Ga, Ge, Ta, W, In, Nb, Mg, REE, PGE  with precious (Au, Ag, Pt) and base metals (Cu, Pb, Sn, Zn, Al). Base metal bearing parts are separated by  mechanical separation technologies based on specific gravity, magnetic and electric properties can be used for their recovery after a proper comminution stage of the raw material. CRM elements and precious metals however can be found often in very fine particles or as alloys, therefore recovery of them can be done only using chemical or biological extraction and separation. 
    Institute of Raw Materials Preparation and Process Engineering, Institute of Mineralogy and Geology of Miskolc University are the main partners in the realization of the subproject. Analytical measurements are carried out by Hungarian Scientific Academy, Research Centre for Natural Sciences

  • 12.01.2014. Surface geophysics in discovering ore enrichments

    Surface geophysics are non-destructive physical methods applied for mineral exploration. The presence of an ore-body may be concluded from the subsurface distributions of the different physical parameters, as determined by the inversion  of the observed geophysical data. In the course of the project we made geophysical measurements in the vicinity of Bükkszentkereszt and Irota and interpreted the geophysical data of Pátka-Szűzvár area. Important beryllium (Be) indications are known in Bükkszentkereszt.   Complex geophysical (magnetic, very low frequency electromagnetic, spectral radiometry, multielectrode resistivity and induced polarization) measurements were made  to gain more knowledge about the host rock of Be ores. It was observed that these  ore zones were overlain by mainly high resistivity and low chargeability metavolcanics.  For further exploration, the simultaneous application of resistivity and induced polarization measurements can be suggested.  In the figure, the geophysical interpretation of the measured apparent resistivity (A) and apparent chargeability (B) along the same profile can be seen. On the right part of the section the effect of separated limestone blocks embedded in clay, in the middle a high resistivity and low chargeability zone of the inhomogeneous metavolcanic bedrock in uplifted situation and on the left from a fault the effect of the gradually ascending metavolcanics, finally appearing on the surface, can be observed.

  • 11.01.2014. Unexpected cobaltite finding in a Darnó borehole
    During our search for PGE minerals, in a basalt sample from the drillhole Rm 135, 543.6 m cobaltite (CoAsS) was found by ore microscopic and microprobe analyses. Until now, this mineral has not been mentioned in this area. The cobaltite forms tiny, 5-10 µm large, angular crystals in another ore mineral, the chalcopyrite (CuFeS2). At the moment, the cobaltite is still a curiosity, significant cobalt enrichment is not known.

  • 10.01.2014 PGE enrichments in Hungarian geological formations?

    Module leader: Dr. Éva Hartai, senior lecturer, foldshe@uni-miskolc.hu

    Are there any PGE enrichments in Hungary? Our research aims to reveal their occurrence and potential grade of enrichment. First we collected all relevant data from the Hungarian  archives and summarized the results in the first volume of the  monographs in the CriticEl project.

    According our research plan the following formations have PGE potential: (1) the Recsk ore complex; (2) Jurassic igneous rocks of the Szarvaskő unit; (3) Triassic volcanics of the Darnó Complex; (4) mafic and ultramafic igneous bodies in deep boreholes in other areas..
    The field work has already been carried out and the available drilling samples were also collected along with the preparation of the samples. Recently the ore microscopic, microprobe and X-ray diffraction analysis, as well as the chemical analysis by ICP -AES method is in progress. Based on the  results a summary evaluation will be carried out. In the sustainment of the project, further research efforts will be paid on the promising areas.

    Energy mineral exploration and critical elements as by-products ENCRITICEL

    There is a growing tendency in several countries to utilize coal resources on a wider basis as replacement of the shrinking potential for imported natural gas. Several minerals and chemical elements are mobilized during these technologies which may as well be utilized as by-products of the energy production. These are germanium and beryllium, which also appear on the criticality list of the EU. An ongoing Hungarian EU co-financed basic research project aims at identifying these potential enrichments in Hungarian mineral resources by combining geological knowledge and processing technology innovation. The proposed follow-up project would scale up the positive achievements of the basic research onto demonstration level on coal occurrences.
