Abstract
Potassium aluminate and phosphate in solution, which may also contain potash or potassium carbonate, are separated by passing gaseous ammonia therein, whereby separation into two layers occurs. The top layer contains nearly pure aluminate, and the bottom nearly all of the phosphate with some aluminate, the quantity of the latter increasing with the concentration of the solution. The layers are separated, and then to complete the separation of the salts, the bottom layer may be diluted with water and treated with ammonia as above. Ammonia is driven off from the respective solutions by heat for re-use, and the solutions worked up to tripotassium phosphate, and alumina and potassium carbonate by know methods. The initial solution may be obtained by treating iron-aluminium phosphate with caustic potash, and removing the insoluble residue, or by leaching the product obtained by calcining iron-aluminium phosphate with potassium carbonate, or with potassium sulphate and carbon, or with potassium chloride and carbon in the presence of steam. The layers are distinguished by possessing different refractive indices, the upper layer by volume being about ten times that of the lower.
