This application proposes an energy-saving method for enhanced smelting of iron-based minerals. The method includes introducing a first reducing agent, fuel, and oxygen-enriched gas into a jet melting zone to melt the added iron-based minerals and flux. The molten slag undergoes partial pre-reduction. Weakly reducing flue gas is extracted and subjected to waste heat recovery and purification treatment to obtain flue gas and dust, with the dust returned to the jet melting zone. The molten slag enters the jet reduction zone, where a second reducing agent is added, and fuel and oxygen-enriched gas are submerged and injected to perform initial reduction, producing molten iron, iron-containing slag, and strongly reducing flue gas. The strongly reducing flue gas is treated to obtain CO gas and dust containing valence metals. The CO gas is pressurized and then introduced into the jet melting zone. This method can effectively process iron-containing minerals and low-sulfur iron-containing slag, and features efficient iron reduction and efficient energy recycling.
