The invention discloses an addition agent for strengthening direct reduction and recovery of iron and copper from copper slag and application of the addition agent, and belongs to the technical fieldof metallurgy and industrial waste slag resource utilization. The addition agent is prepared from the components in percentage by mass: 50-60% of an alkaline earth metal source, 30-50% of pyrolusite and 5-10% of sodium humate. According to the addition agent for strengthening direct reduction and recovery of the iron and the copper from the copper slag and the application, component distribution is reasonable, the production technology is simple, using is convenient, and the functions that catalytic reduction of copper and iron mineral is achieved, the reduction kinetic condition is improved,and pelletizing is strengthened are achieved. According to the technology, the awkward situation that in an conventional method, separation is difficult due to tight embedment of copper and iron in copper smelting can be avoided, highworth utilization of copper smelting slag is achieved, iron powder containing copper with high quality can also be obtained through magnetic separation and replaces electrolytic copper, furnace burden with high quality is provided for smelting special steel containing copper, the production cost of the special steel containing copper is lowered, and economic benefits are improved.
