Process for shipment of sodium cyanide slurries

摘要

A process for manufacturing, shipping and unloading substantially solid, ice-like sodium cyanide dihydrate containing essentially no liquid water. A slurry of 58 weight percent or higher sodium cyanide is rapidly cooled to the anhydrous/dihydrate transition temperature while minimizing the settling out of sodium cyanide crystals to form the product in a container. Dissolution prior to unloading is by adding heat and water or dilute sodium cyanide solution.
