Исследована возможность повышения объемов переработки магнетит-апатитовых руд Ковдорского месторождения. Исследования были направлены на изучение влияния операции предварительного грохочения на показатели измельчения и последующего магнитного обогащения. Установлено, что наибольший прирост производительности секции обогащения в 22 % достигается при крупности материала предварительного грохочения 0,56 мм.
