Sodium cyanide, a highly toxic substance, the method of manufacturing it needs to be detailed and prudent.

Initially, prepare all the required materials, among which the key materials should be finely ground with a specific ore, mixed with an appropriate amount of alkali agent in a special container. Next, apply a precise heat and heat it slowly in a closed space. In this process, temperature control is crucial, and if it is slightly exceeded or not, it will affect the quality of the product.

When heating, closely observe the reaction. After the contents of the container are in a specific state and the reaction is confirmed after delicate testing, the subsequent steps can be entered. Use a fine filter to remove its impurities and retain the essence. Then the liquid is cleverly evaporated and concentrated, so that it gradually becomes crystalline.

However, the manufacture of sodium cyanide is related to human life safety and must not be negligent. The place must be fully protected, and the operator must be familiar with the procedures to prevent accidental poisoning and cause disaster. Every step is strictly followed in order to obtain usable sodium cyanide, and to protect the environment and personal safety.
