As in a purely active system, motility of the active component triggers phase separation into a dense and a dilute phase; in the dense phase we further find active-passive segregation, with \"rafts\" of passive particles in a \"sea\" of active particles. We find that phase separation from an initially disordered mixture can occur with as little as 15 percent of the particles being active.
