A method for producing mixed slag containing nickel and iron, comprising the following steps: S1. furnace slag mixing: adding nickel smelting slag into a reaction apparatus, and adding one or more of lead smelting slag, blast furnace slag, steel slag, and ferro-alloy slag to form mixed slag; heating the mixed slag to a molten state, and simultaneously adding one or more of a copper oxide mineral, a copper sulfide mineral, a nickel oxide mineral, a nickel sulfide mineral, and a copper-containing material; uniformly mixing same, using the mixture as reaction slag, and monitoring the reaction slag in real time; moreover, performing regulation and control to enable the mixed reaction slag to satisfy both condition a and condition b, the condition a being that the temperature of the reaction slag is controlled to range from 1050°C to 1450°C, and the condition b being that a alkalinity CaO/SiO2 ratio of the reaction slag is controlled to range from 0.15 to 1.5; obtaining reacted slag; and S2. performing separation and recycling.
