We report on the elliptic and triangular flow measurements for a number of hadrons including charged pions, and (anti-)protons, as well as those with strangeness content: phi-meson, Lambda/Lambda, Xi, and Omega. The results reported cover mid-rapidity, vertical bar eta vertical bar <0.8, and a wide, 0.2 < p(T) < 16 GeV/c, transverse momentum range for Pb-Pb collisions at root S-NN = 2.76 TeV recorded by ALICE at the LHC. The mass splitting and the scaling properties of the elliptic flow with the number of constituent quarks and the particle transverse mass are studied as a function of collision centrality. The results are compared to RHIC measurements and to hydrodynamic model predictions.
