      <abstract xml:lang="ru">
        <p>Титановое сырье находит широко применение для синтеза различных функциональных материалов – сорбентов радионуклидов и редкоземельных элементов, разных добавок, пигментов-наполнителей и др. Ввиду того, что основное количество титановых концентратов импортируется из-за рубежа, в рамках программы импортозамещения получение титанитового концентрата из апатит-нефелиновых руд Хибинских месторождений является перспективным направлением для обеспечения титановым сырьем отечественной промышленности. В статье представлены результаты лабораторных исследований флотационного выделения титанитового концентрата из апатит-нефелин-титанитовых руд, отобранных с верхнего рудного горизонта Коашвинского месторождения, где сконцентрированы руды, обогащенные титанитом. Выделение титанитового концентрата осуществлялось с использованием двух реагентных режимов – смесь алкилгидроксамовых и карбоновых кислот с добавкой дистиллированного таллового масла и смесь талловых масел с добавкой полиалкилбензолсульфокислот. Результаты исследований показали, что наиболее эффективным режимом флотации, позволяющим селективно выделять титанит в концентрат (содержание титанита в концентрате составило 93,5 %), является первый режим. Показано, что флотационное выделение титанитового концентрата предпочтительнее по сравнению с химическим способом, основанным на сернокислотном выщелачивании.</p>

        <p>Titanium raw materials are widely used for the synthesis of various functional materials – sorbents of radionuclides and rare earth elements, various additives, filler pigments, etc. Since most of titanium concentrates are imported, in line with the import substitution program, production of titanite concentrate from apatite-nepheline ores of the Khibiny deposits is a promising trend for supplying national industry with titanium raw materials. The article presents the results of laboratory studies of flotation separation of titanite concentrate from apatite-nepheline-titanite ores extracted from the upper ore horizon of the Koashvinskoye deposit, where titanite-enriched ores are concentrated. Recovery of titanite concentrate was accomplished using two reagent modes – a mixture of alkyl hydroxamic and carboxylic acids with the addition of distilled tall oil and a mixture of tall oils with the addition of polyalkyl benzene sulfonic acids. The results of the research showed that the first flotation mode, which allows a selective recovery of titanite into the concentrate (titanite content in the concentrate was 93.5 %) is the most efficient. It was shown that flotation separation of titanite concentrate is preferable compared to the chemical method based on sulfuric acid leaching.</p>
