    摘要： The invention relates to a method for producing shaped inorganic cyanide bodies, especially made of alkaline metal cyanides and alkaline earth metal cyanides, by pressing particulate inorganic cyanide obtained by means of a crystallization method. According to the invention, a cyanide crystallate separated from a mother liquor by means of a solid-liquid separation device and containing 2-15 wt. % water is fed to a forming device without the addition of an auxiliary forming agent and placed under pressure and compressed to form shaped bodies containing 0.1-12 wt. % water. The amount of water contained by the shaped bodies is always less than that contained in the crystallates used for the production thereof. Preferably, the crystallite is pressed out of a rotary filter or a centrifuge at a temperature of more than 40° C. to form shaped bodies containing 0.2-6 wt. % residual water. The inventive method can be carried out in a more economical manner than previously known methods using dried cyanide. The invention also relates to shaped inorganic cyanide bodies obtained according to said method.

    摘要翻译： 本发明涉及一种通过压制通过结晶法获得的无机氰化物来生产特别是由碱金属氰化物和碱土金属氰化物制成的成形无机氰化物体的方法。 根据本发明，通过固液分离装置从母液中分离出含有2-15wt。 将％水加入到成形装置中，而不加入辅助成形剂并置于压力下并压缩形成含有0.1-12wt。 ％ 水。 成形体所含的水量总是小于用于生产的结晶中含有的水。 优选地，微晶在大于40℃的温度下从旋转过滤器或离心机中压出以形成含有0.2-6wt。 ％残留水。 本发明的方法可以比使用干燥氰化物的已知方法更经济的方式进行。 本发明还涉及根据所述方法获得的成形无机氰化物体。
