Abstract
Mixed state can be used in dense coding. We have analyzed here that maximally entangled mixed states like Werner state is dense codeable for a certain range of state parameter whereas for some wider range of the state parameter the state is steerable' but cannot be used in dense coding. For qutrit system we consider isotropic states and have found similar characteristics, like the states are steerable' for a range of state parameter but for a sub range of that steerability range only, the states are dense-codeable.

This paper has some errors pertaining to my understanding of the concept of steering, for which it has been withdrawn
