The possibility of processing of serpentine magnesite raw Khalilovo deposit on the particulate silica. Optimum performance stages and process parameters of sulfuric acid decomposition SMN. In the experiment on the acid degradable serpentinite magnesite raw product was obtained with a high dispersion, but with a high iron content. For reducing the concentration of iron in the product, the original serpentine magnesite raw material enriched by magnetic separation. After this experience had a sulfuric-acid decomposition enriched SMN.
Изучена и показана возможность переработки серпентинит-магнезитового сырья Халиловского месторождения на высокодисперсный диоксид кремния. Определены параметры процесса сернокислотного разложения и показатели отдельных стадий. Показано, что при переработке исходного серпентинит-магнезита получаемый диоксид кремния имеет повышенное содержание железа. Найдено, что магнитной сепарацией удаётся снизить концентрацию железа в сырье и продукте, получаемом из него.
