A method of and service for searching computerized networks, such as the internet, that first performs a search based on a user query to produce results that are ranked. The system uses two magnetic rings offset a distance, each ring having a continuous arc of magnetic material terminating in a blind zone, where the blind zone produces a magnetic field substantially different from the continuous arc region. The second crystallizer is structured and adapted to precipitate recycle crystals from the concentrated liquor to form a potassium-depleted recycle brine.
