For example, the graphite-oil agglomerates can be separated from the water and graphite grinding aid by filtering with bar sieves or screens which predominately retain the graphite-oil agglomerates, but pass water and unagglomerated graphite grinding aid. The result is a physical separation of the graphite grinding aid from graphite.Web
