The invention relates to the technical field of building materials, in particular to a production process of high-activity composite superfine slag powder. Crushing the slag raw material through a crusher, and carrying out drying pretreatment on the slag raw material to obtain a to-be-ground raw material; the to-be-ground raw materials are ground and smashed through a filtering and grinding machine till the particle size of the to-be-ground raw materials reaches a threshold value range, and ground powder is obtained; according to the method, the slag is firstly crushed and then dried, the size of the slag is reduced, the drying efficiency is improved, moisture in the slag is removed through drying of the slag, subsequent grinding and powder making of a filtering and grinding machine are facilitated, the grinding frequency is increased on the basis of a traditional technology, the slag grinding time is prolonged, and the slag micro-powder is obtained. Scrap iron in the ground powder is adsorbed by electromagne
