The continuous binary mixture of hard spheres interacting through an attractive Yukawa tail is considered. The explicit expressions for the partial structure factors $S_{\alpha \beta }({\bf {k}})$ and the concentration- concentration structure factor $S_{cc}({\bf {k}})$ are derived in the random phase approximation. The influence of variations of microscopic parameters on the behaviour of the curves $S_{\alpha \beta }({\bf {k}})$ and on the temperature of spinodal $T^*$ is investigated. The collective variables (CV) method with a reference system (RS) is applied to the study. The results are compared with the analogous ones obtained by the method of integral equations and Monte-Carlo method.
