Abstract

A process for the production of sodium cyanide with urea and sodium carbonate as main raw materials comprises: a) step for blending raw materials; b) step for first-order reaction; c) step for second-order reaction; d) step for centrifugal atomization; e) step for agitating and dissolving; f) step for precipitating and filtering; g) step for vacuum distillation; and h) step for centrifugal separating and drying. High purity (above 98%) of sodium cyanide finished product may be obtained.
