ABSTRACT:
For extracting phosphates with alcohol in the presence of water and a strong mineral acid, with the resultant formation of an alcoholic phosphoric acid solution and an aqueous salt phase, a plurality of mixing settlors are arranged one upon another, so that the bottom outlet for the aqueous salt phase of each mixing settlor serves as the feeder for the next mixing settlor below and the outlet for the alcoholic solution of each settlor is connected with the feed pipe for this solution of the next mixing settlor above. Each mixing settlor is subdivided by means of two partitions into a mixing chamber A, a separating chamber B and a settling chamber C. The said two partitions do not extend to the bottom of the mixing settlor and are arranged so that the three chambers A, B and C communicate with one another.
