      <abstract xml:lang="ru">
        <p>Доломитизация фосфоритовых руд повышает содержание MgO, что ухудшает качество руд и в ряде случаев переводит их в разряд некондиционных, забалансовых. Доломитизации подвержены отдельные локальные участки месторождения. Естественно, их желательно выявить в процессе проведения разведочных работ и исключить из числа балансовых запасов. ...</p>

      <abstract xml:lang="en">
        <p>Dolomitization of phosphorite ores increases the content of MgO, which deteriorates the quality of ores and in some cases converts them into the category of substandard, off-balance ores. Individual local areas of the deposit are subject to dolomitization. Naturally, it is desirable to identify them during exploration operations and exclude them from the balance reserves. ...</p>
