Emmett amp Dahlstrom 1974 summarized it well by stating In its simplest form, washing in a thickener can consist of mixing solids and associated solution with water, settling the solids, decanting the clarified solution, and then repeating the process as required until the dissolved material is removed.\quotThe logical extension of this procedure is to use the more dilute, decanted soSee more on westech incLive Chat
