The most reasonable way of recycling the metal composite materials consists in separation of the components. In case of the composites with saturated reinforcement it is the only recycling method. The process of separation of the components always undergoes in the presence of an additional liquid phase called a recycling medium. In a three-phase system including the material of composite reinforcement - liquid composite matrix - liquid recycling medium, an important role for the recycling process is played by the changes in energy values at the interfacial surfaces. Proper choice of the recycling medium enables simultaneous process of transition of the reinforcing phase particles into the environment (the suspension composites) or also simultaneous outflow of the metal matrix from the reinforcement capillaries (the composites with saturated reinforcement). Moreover, a very important role in recycling of composite materials with saturated reinforcement is played by geometry of the reinforcement material capillaries. Energetic conditions render impossible simultaneous outflow of the matrix from the capillaries of varying and irregular geometry. It means that a choice of proper recycling medium is necessary condition for the recycling process, although not always a sufficient one.
