How to Turn Steel Slag into a Valuable Resource

Steel slag is a waste residue generated in the metallurgical industry, accounting for 8% to 15% of crude steel production. The treatment and resource utilization of waste slag from steel enterprises are receiving increasing attention. Failure to promptly process steel slag produced by steel enterprises results in large quantities of slag occupying land and polluting the environment. However, steel slag is not merely unusable solid waste. It contains substantial recoverable components such as slag steel, calcium oxide, iron, and magnesium oxide. Therefore, selecting appropriate processing technologies and utilization pathways to unlock the reuse value of steel slag is both essential and urgent for steel enterprises to achieve economic and environmental benefits.

As a company committed to the “green and eco-friendly” philosophy, OCP Heavy Industry Co., Ltd. has conducted in-depth research on the efficient comprehensive recovery and utilization of steel slag. OCP manufactures specialized coarse crushing equipment for steel slag—the P-series single-cylinder hydraulic jaw crusher—and has subsequently developed dedicated equipment including the H-series single-cylinder hydraulic cone crusher for steel slag, slag steel purification autogenous mills, and energy-efficient steel slag ball mills. These can be applied to both dry and wet processing methods for steel slag. The company's proprietary magnetic steel slag washing, ball milling, magnetic separation, and purification processes, along with integrated slag-slurry recycling technologies and complete equipment sets, not only enable water circulation but also achieve high-grade steel slag purification (TFe > 90%) with iron-containing slag powder grades reaching 55%. Tailored to the specific characteristics of each steel enterprise, the company has developed both dry and wet production processes and complete sets of equipment for the efficient comprehensive recovery and utilization of steel slag. With production capacities ranging from 300,000 to 2,000,000 tons per year, these solutions offer steel slag processing plants a choice for achieving efficient comprehensive utilization and zero emissions. This provides steel enterprises with complete sets of efficient, energy-saving processes and equipment to support circular development and build resource-conserving enterprises.
