WebSubsequent testing of waste rock and LGO blast fines showed that rock initially classified as potentially acid-generating (PAG) was expected to behave as non-PAG in stockpiles. SRK evaluated the influence of rock type and age of the rock on ARD potential in several blast rock size fractions ranging from -2 mm to +25 mm. Samples were analysed by ... WebThe post-depositional sampling of non-PAG rock confirmed its characteristics but PAG waste rock and low-grade ore showed it had low potential for ARD (i.e. non-PAG). SRK determined that blasting preferentially partitioned acid-consuming minerals into blast fines, which was linked to these minerals occurring as fracture fillings in the rock.
