One way is to crush the limestone to −3 mm size and then to process it in a scrubber and classifier. Another entails grinding the raw feed to less than 200 mesh and then to carry out beneficiation by a froth flotation method,,, . In the present case, a low grade limestone sample was processed using the column flotation technique.

The various types of foliated metamorphic rocks, listed in order of the grade or intensity of metamorphism and the type of foliation are slate, phyllite, schist, and gneiss (Figure 7.8). As already noted, slate is formed from the low-grade metamorphism of shale, and has microscopic clay and mica crystals that have grown perpendicular to the stress.

At 0.5 ml AMD/g media, LGO increased the pH of AMD to 5.36 while limestone completely neutralized it. LGO removed more than 99% of Al and Fe, 94% of Ni, and 93% of sulfates compared to a 70% sulfate removal using limestone.

Low-grade metamorphism takes place at temperatures between about 200 to 320 o C, and relatively low pressure. Low grade metamorphic rocks are generally characterized by an abundance of hydrous minerals. With increasing grade of metamorphism, the hydrous minerals begin to react with other minerals and/or break down to less hydrous minerals.
