  We investigate the effects of intermittent strong jets from an Active
Galactic Nuclei (AGN) of a massive galaxy in the core of a cool core galaxy
cluster, on the dynamics and metal distribution of the intra-cluster medium
(ICM). We use a simple model for the metal distribution within the host galaxy
which includes metal injection via star formation. We carry out 2D axisymmetric
hydrodynamic simulations of these systems. After having established a cooling
flow, two light jets are injected in opposite directions with a range of
(intermittent) active phases. We follow the time evolution of the system from
the jets' active phases up to 3 Gyr. The general metallicity evolution for all
our simulations is very similar on large-scales. The convective flows driven by
the jets advect gas and metals from the central galaxy to distances beyond 1.5
Mpc within the cluster. Intermittent jets are able to distribute metals to
grater radii. The metal injection has effects on the general metal abundances
present in the ICM, the faster the metal replenishment time the higher the
metal abundance. Although metallicity gradients in the very central regions of
cool core clusters are likely to be shaped by less-energetic phenomena, we find
evidence in our simulations for metallicity gradients similar to those observed
out to ~400 kpc radius. The metal distribution details of the central galaxy
have no effects on the dynamical evolution of the ICM metals.
