Attention is focused on the low-ion-velocity stopping mechanisms in multicomponent and dense target plasmas built of quasi-classical electron fluids neutralizing binary ionic mixtures. The target plasma is taken in a multicomponent dielectric formulation à la Fried-Conte. The occurrence of projectile ion velocities (so-called critical) for which target electron slowing-down equals that of given target ion components is also considered. We emphasize the strongly asymmetric BIM targets such as the proton-boron 11 of thermonuclear concern and the strongly mass-asymmetric proton-U238+.
