Медно-никелевые месторождения расположены по всему миру. При их разработке образуется большое количество нерудного сырья. Оно перемещается в отвалы и создает экологические риски для окружающей среды. В отвалах преобладают магнийсодержащие породы, которые необходимо утилизировать. Цель работы – изучить возможность их использования в производстве строительных материалов. Методы. Химический анализ выполнялся методами гравиметрии, фотометрии, атомно-адсорбционной спектроскопии. Минеральный состав изучен с помощью рентгенофазового анализа. Механические показатели определялись на испытательном гидравлическом прессе. Результаты. Установлено, что щебень из магнийсодержащих пород имеет высокое качество и может использоваться как крупный заполнитель при получении бетонов. Показано, что большую прочность имеют бетоны, содержащие в своем составе щебень из ультраосновных пород – верлитов, наименьшие показатели у бетона на гранитном щебне. Вид условий твердения также оказывает влияние на прочность получаемого материала. Песок из отсевов дробления горной массы имеет минеральный состав как у материнской породы, а также угловатую форму зерен. Это способствует компоновке плотной структуры бетонного камня, повышающей его прочность более чем на 10%. Заключение. Использование нерудного сырья сократит объемы отвальных пород, образующихся при добыче полезных ископаемых. При этом можно получать готовый товарный продукт – щебень из магнийсодержащих пород и песок от их дробления. Это позволит решить экологические, экономические проблемы, а также производить необходимые строительные материалы для собственных нужд.</p></abstract><trans-abstract xml:lang="en"><p>Aim. Copper-nickel deposits are located all over the world. A large amount of nonmetalliferous raw materials is formed, when they are developed. It moves into dumps and creates environmental risks for the environment. In the dumps magnesium-containing rocks prevail, which must be disposed of. The purpose of the work is to study the possibility of their use in the production of building materials. Methods. The chemical analysis was carried out by gravimetry, photometry, and atomic-absorption spectroscopy. The mineral composition was studied using X-ray phase analysis. The mechanical parameters were determined on a test hydraulic press. Results. It is established that the crushed stone from magnesiumbearing rocks is of high quality and can be used as a large aggregate in the production of concretes. It is shown that the concrete, containing crushed stone from ultrabasic rocks - verlites show the most compression strength. The lowest values has ordinary concrete on granite crushed stone. The type of hardening conditions also affects the strength of the resulting material. Sand from the sifting of crushing rock mass has angular shape of the grains and a mineral composition as in the parent rock. This contributes to the design of a dense structure of concrete stone, which increases its strength by more than 10%. Main conclusions. The use non-metalliferous raw materials will reduce the volumes of waste rock formed during the development of mineral deposits. In this case, it is possible to obtain a finished commodity product - crushed stone from magnesium-containing rocks and sand from their crushing. This will solve environmental, economic problems, as well as produce the necessary building materials for their own needs.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>нерудное сырье</kwd><kwd>магнийсодержащие породы</kwd><kwd>отходы горнодобывающей промышленности</kwd><kwd>бетоны</kwd><kwd>щебень</kwd><kwd>песок</kwd><kwd>минералогический состав</kwd><kwd>гранулометрический состав</kwd><kwd>предел прочности на сжатие</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nonmetalliferous raw materials</kwd><kwd>magnesium-containing rocks</kwd><kwd>mining industry waste</kwd><kwd>concrete</kwd><kwd>crushed stone</kwd><kwd>sand</kwd><kwd>mineralogical composition</kwd><kwd>granulometric composition</kwd><kwd>compression strength</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Налдретт А.Дж.
