Strangeness enhancement was one of the main pieces of evidence for CERN's claim to have produced a deconfined matter of quarks and gluons, a Quark Gluon Plasma (QGP). Measuring strange particles at the LHC will provide direct information about the production mechanism and chemical composition of the system produced. Moreover, these results could shed light into hadronisation, a topic that remains a challenge to our understanding of QCD. In this seminar, prospects for Phi meson production at the LHC will be presented. The role this could play both in heavy-ion and proton-proton physics will be explained. Another key signature for the formation of a QGP state has been the observed J/Psi suppression in heavy ions. In this seminar, detailed simulation results for the J/Psi decaying into dimuons will also be presented. These two studies are expected to be among the first particle measurements at the ALICE experiment.
