In this paper, we present the definition of mixed uninorms and propose several methods for constructing two special classes of mixed uninorms on bounded lattices through t-subnorms and t-superconorms. These methods generalize $\mathbb{U}_{\min},$ $\mathbb{U}_{\max},$ $\mathbb{U}_{\min}^{1}$ and $\mathbb{U}_{\max}^{0}$ on bounded lattices that have been previously discussed in the literature. Some examples are given to construct mixed uninorms on bounded lattices.
