A method for preparing basic zinc chloride is provided. The present invention relates to a method for preparing basic zinc chloride, and particularly to a method for preparing feed additive basic zinc chloride. An objective of the present invention is to provide a low-cost, safe and environment-friendly method for preparing basic zinc chloride, and the method is characterized in that basic zinc chloride is prepared from zinc chloride and calcium hydroxide through reaction. According to the present invention, basic zinc chloride is successfully prepared by using zinc chloride and calcium hydroxide through reaction for the first. The method is simple, the process is short, the reaction costs are low, and the wastewater generated during reaction can be easily treated and is safe and environmentally friendly. The zinc content, the chlorine content, the arsenic content, the lead content and the cadmium content in the finished basic zinc chloride prepared by the method of the present invention fully comply with national standards for feed grade basic zinc chloride, so the finished basic zinc chloride prepared by the method of the present invention can be directly used as feed additive. |
