Abstract

Processes for forming ferric chloride solutions that are stable at relatively low temperatures and suitable for transportation without precipitation are provided. The stable ferric chloride solutions have an iron content of about 16 to about 23 weight percent and a hydrochloric acid content of about 11 to about 17 weight percent, wherein the ferric chloride solution is a stable solution and/or reversibly freezes at −10° C. Also disclosed are processes for reconstituting the stable ferric chlorides solutions to provide a final iron content of 10 to 14 weight percent and lower the concentration of hydrochloric acid contained therein.
