ABSTRACT Potassium nitrate is produced by contacting nitric acid with a potassium loaded strong cationic exchange resin. In a preferred embodiment, a solution of potassium nitrate and dilute nitric acid is produced in a continuous liquid solid contacting apparatus. The preferred apparatus is formed of a plurality of resin filled chambers which rotate in and out of periodic fluid communication with fixed feed and discharge ports. The apparatus design allows for continuous supply of a nitric acid solution, potassium chloride regeneration solution, wash solutions, and air streams to ports arranged in zones, so that resin filled chambers pass through the zones to continuously produce a solution containing potassium nitrate and dilute nitric acid. In a preferred embodiment, the solution of potassium nitrate produced is neutralized with potassium hydroxide to convert residual nitric acid to potassium nitrate.
