2017-1-20Separation processes are based on the theory of vapor-liquid equilibrium. This theory states that streams leaving a stage in a separation process are in equilibrium with one another. The idea of equilibrium revolves around the idea that when there is vapor and liquid in contact with one another they are in constantly vaporizing and condensing.
2018-2-20Dense medium separation DMS is a robust process that can be conducted at particle sizes as coarse as 300 mm and as fine as 500 m with high separation efficiency, depending on liberation characteristics of the value minerals. The DMS process involves three steps feed preparation, dense medium separation, and ferrous-based media recovery.
