  The ALICE experiment at the Large Hadron Collider (LHC) ring is designed to
study the strongly interacting matter at extreme energy densities created in
high-energy heavy-ion collisions. In this paper we investigate correlations of
heavy and light flavours in simulations at LHC energies at mid-rapidity, with
the primary purpose of proposing experimental application of these methods. Our
studies have shown that investigating the correlation images can aid the
experimental separation of heavy quarks and help understanding the physics that
create them. The shape of the correlation peaks can be used to separate the
electrons stemming from b quarks. This could be a method of identification
that, combined with identification in silicon vertex detectors, may provide
much better sample purity for examining the secondary vertex shift. Based on a
correlation picture it is also possible to distinguish between prompt and late
contributions to D meson yields.
