9619. Parker, C. L. April 27. Sodium and iron sulphates.-Nitre-cake or acid sodium sulphate is treated with a large excess of scrap iron, according to the method of Specification No. 24,639, A.D. 1903, except that the specific gravity of the solution used is 1275 to 1300. The resulting solution of sodium and ferrous sulphates (preferably left slightly acid with sulphuric acid) is allowed to settle, and then drawn off, and the sodium sulphate crystallized out. The mother liquor is treated with a large excess of scrap iron in another vessel, is evaporated, the ferrous sulphate crystallizing. Oxide, hydrate, or carbonate of iron, or spathose or similar iron ore may be used in the above process.
