      <abstract xml:lang="ru">
        <p>Показаны возможности высокоимпульсной обработки тонковкрапленных минеральных комплексов, позволяющей при обогащении упорных золотосодержащих руд и продуктов обогащения получить стабильный прирост извлечения ценных компонентов (золота на 30-80 %, серебра - на 20-50 %) при уменьшении энергозатрат и снижении себестоимости готовой продукции. Приведены результаты теоретических и экспериментальных исследований механизмов нетеплового воздействия мощных электромагнитных импульсов с короткими (наносекундными) фронтом и длительностью при напряженности электрической компоненты поля порядка 107 В/м на природные минеральные среды сложного вещественного состава.</p>

      <abstract xml:lang="en">
        <p>In 2001-2002, the Talnakh Concentrator (Talnakh Concentrator) of the Polar Division of MMC Norilsk Nickel implemented a number of measures aimed at improving the ore concentration technology at the Talnakh and Oktyabrskoye deposits in order to improve the quality of nickel and copper concentrates. A side effect of the implementation was a significant reduction in the amount of pyrrhotite concentrate (PC) supplied for processing to the hydrometallurgical production (HMP) of the Nadezhda Metallurgical Plant (NMZ). In 2003, a method of improving the autoclave-oxidation technology for processing PC with high pyrrhotite content was introduced into industrial production, which provides for the involvement of intermediate products of ore enrichment at Talnakh Concentrator into the HMP of NMP. This allowed to increase the output of non-ferrous and precious metals from "off-balance" raw materials while optimizing the utilization of the existing capacities of the NMP; to increase the stability of the oxidative leaching process of high-sulfur coarse-dispersed PCs and to improve the technological performance of the Talnakh Concentrator and the NMP. The actual economic effect obtained during 5 months of the development utilization amounted to 176 mln rub.</p>
