Abstract
The invention relates to a process for recovering from potassium mineral refining tailings sodium chloride of sufficiently high purity, characterised by comprising the following stages a) washing said refining tailings with water and with the mother liquor from one or more successive stages of the process which contains sodium chloride as its base component, to give a mixture of a solid phase comprising nearly all the sodium chloride contained in said fed tailings, and a liquid phase b) separating said mixture into a first turbid portion enriched in said solid phase, and a second turbid portion enriched in said liquid phase c) separating the sold phase from the liquid phase of said first turbid portion, this latter separated phase constituting at least part of said mother liquor fro use in stage a) and possibly d) drying the solid phase separated in stage c) to produce high purity sodium chloride.
