        <p>Рассматриваемая проблема включает решение вопросов снижения вторичных потерь глинозема и щелочи при выщелачивании алюминатного спека и повышения технико-экономических показателей процессов сгущения и промывки нефелинового шлама за счет применения комбинированных добавок коагулянтов-флокулянтов типа карбоалюминат-алклар. В соответствии с поставленными задачами выполнен аналитический обзор, проведены патентные исследования и обоснованы направления дальнейших исследований.</p>

        <p>The problem under consideration includes the solution of secondary losses of alumina and alkali during aluminate sinter leaching and improvement of technical and economic performance of nepheline slurry thickening and washing processes through the use of combined coagulant-flocculant additives of carbon-aluminate-alklars type. In accordance with the set tasks an analytical review was carried out, patent research was carried out and directions of further research were substantiated.</p>
