Ore powder binder is a functional material that enables adhesion between ore powder particles, thereby transforming dispersed ore powder into blocks or pellets with certain strength, shape, and performance. In modern industries such as metallurgy and mining, the application of ore powder binders effectively addresses issues like low utilization rates of ore powder and transportation difficulties, playing a significant role in improving production efficiency and reducing costs.
From the perspective of composition and properties, ore powder binders can be classified into organic binders, inorganic binders, and organic-inorganic composite binders. Organic binders, such as starch-based, cellulose-based, and synthetic resin types, offer advantages like high bonding strength and good plasticity, making them widely used in scenarios requiring high strength for formed products. Inorganic binders, including water glass and cement, are characterized by high-temperature resistance and low cost, often employed in smelting processes where high-temperature performance is essential. Organic-inorganic composite binders combine the benefits of both, ensuring certain bonding strength while providing excellent high-temperature resistance and stability.
The role of ore powder binders is reflected in multiple aspects. In terms of shaping, it promotes tight bonding between ore powder particles, enabling the formation of pellets, lump ore, and other shapes according to production needs, facilitating subsequent processing. In enhancing strength, the adhesive network formed by the binder increases the connection force between particles, improving the compressive and wear resistance of the formed material and reducing damage during transportation and use. In improving metallurgical performance, suitable binders can optimize the permeability and reducibility of ore powder during smelting, enhancing efficiency and product quality. Additionally, the use of ore powder binders allows for the reuse of previously difficult-to-utilize fine ore powder and tailings, increasing resource utilization and reducing waste and environmental pollution.
The application scenarios of ore powder binders are extensive. In the steel metallurgy industry, they are used to produce pelletized or sintered ore from iron concentrate powder, serving as high-quality raw materials for blast furnace ironmaking. In non-ferrous metal smelting, they enable the shaping of metal ore powders such as copper, lead, and zinc to meet the requirements of various smelting processes. In the chemical industry, binders are employed to create materials with specific shapes and properties from special ore powder raw materials for the production of chemical products. In the environmental protection sector, ore powder binders can also be used to treat industrial waste slag by mixing and forming it with ore powder, achieving resource utilization of waste.
With continuous advancements in industry technology, ore powder binders are also evolving. In the future, they will develop towards environmentally friendly, high-performance, and multifunctional directions to meet increasingly stringent environmental requirements and evolving production process needs, thereby creating greater value in more fields.
