Abstract
Chemical processing of two dolomitic magnesite rocks by scrubbing with dilute hydrochloric acid has delivered magnesia concentrates of good quality, containing very low levels of calcium oxide. The recovered magnesia samples were used for the preparation of magnesia and magnesia-chrome refractory bricks of acceptable properties.
