The invention discloses a production method for smelting manganese-series iron alloys by utilizing crystalline silicon cutting waste powder as a reducing agent. The production method is characterized in that all or part of cutting mortar waste powder in the solar photovoltaic crystalline silicon slicing industry replaces coke as a reducing agent, and the reducing agent is directly added into manganese ore raw materials; current equipment is adopted to carry out smelting operation, so that reduction reaction is carried out on manganese oxide, iron oxide or silicon dioxide in silica ingredients under a high-temperature melting state by utilizing high energy consuming characteristic and strong reduction characteristic of high-purity simple substance silicon and silicon carbide in the cutting mortar waste powder so as to obtain manganese-series iron alloy products. According to the trial, the production method truly has the outstanding advantages that the process technology is simple and is easy to grasp, silicon
