The use of variability samples covering the main min-
eralized geological units through LOM have confirmed the
amenability of the Santo Domingo ore to the proposed iron
concentrate plant design.
Complementary pelletizing testwork demonstrated the
physical and metallurgical quality of the Santo Domingo
iron concentrate for blast furnace grade feed.
