The invention belongs to the technical field of chemical industry catalysts and particularly relates to a production method for a copper-zinc catalyst. The production method for the catalyst, disclosed by the invention, comprises the steps of subjecting precipitated slurry to spray drying, and then, subjecting spray-dried particles to pre-tabletting so as to form tablets with larger size, so as to replace the traditional method which comprises the steps of carrying out a material crushing procedure, then, crushing the tablets with larger size into particles with particle size smaller than 2mm by adopting a crusher, and then, carrying out tabletting so as to form the finished product of required specifications. According to the production method, accurate control on materials of different properties is achieved in a manner of controlling different compression ratios, so that control indexes are quantified, the labor intensity is lowered, and the product quality can be more stable.
