On the matter of composition and technological properties of uranium ores of the Semizbai deposit (North Kazakhstan)

Currently, uranium production occupies a decisive place in the world energy industry. In Kazakhstan, to meet demand for uranium, hydrogenous deposits with technologically and economically favorable natural indicators are being developed, including large Semizbai deposit. The deposit by genesis belongs hydrothermal-hydrogenous polygenic type terrigenous sandy-clayey deposits. As result of geological studies, stratification ore-bearing suite was established: lower upper sub suites, geometrization performed, morphology, number, size ore bodies were identified. Most balance reserves concentrated medium bodies. Analytical work description thin sections polished under microscope determined material composition, textures, structures ores, main minerals, their distribution ores. When carrying out field laboratory work, obtained select technology extracting To justify development technology, special technological studies carried experimental area. Based on ores Semizbay deposit, well-in-situ leaching chosen as most rational characteristic associated useful components is given, increased content selenium, germanium, scandium them established. research results can serve basis improving used mining from them.
