Abstract
Sodium cyanide is obtained from mixtures or solutions containing it together with sodium chloride and alkaline earth compounds such as the product obtained by fusing calcium cyanamide with sodium chloride, by precipitating the alkaline earth by adding a suitable sodium salt, such as sodium sulphate or carbonate, and concentrating the solution at the same time, or subsequently so as to salt out the sodium chloride and leave the cyanide in solution. For this purpose, sodium cyanide or its mixture with sodium chloride, may be added to the solution. If an excess of cyanide is used, the part remaining undissolved may be recovered by leaching the remaining solids.
