Slag application prospects

Release date: 2022-10-24

The application prospect of slag is still very good, but it needs to be ground with a slag grinding mill before processing. The slag itself has little or no hydraulic gelling properties, but it participates in the chemical reaction of calcium hydroxide or other hydroxides in the presence of moisture after grinding, especially under steam curing conditions. And generate a compound with hydraulic gelling properties. Therefore, it can be used as a building material, commonly used in the production of large-scale samples of cinder or slag concrete, etc., and the slag can also be used for road construction or as insulation and sound insulation materials in houses.

Some rare metals remain in the slag. According to historical records, germanium, barium, uranium and other components can also be recovered from the slag since 1896.

The slag generally contains 10-20% carbon. Coal is processed by the process of roasting, leaching, purification and reduction of vacuum steaming selenium slag. The test results show that the recovery rate of selenium is 90.09%, and the grade of selenium powder is >99.5%. Selenium slag roasting leaches selenium generally from copper, lead and nickel electrolytic anode slimes, acid slimes produced by sulfuric acid and washing of pulp produced.

If the carbon-containing combustibles in the slag are not recovered, it will not only seriously waste national resources, but also have a bad influence on the comprehensive utilization of the slag. Therefore, in some cities, the slag with high carbon content is made into briquettes for daily use, and then burned once, the thermal energy of coal is fully recovered.

Since the slag is a porous alkaline substance, it can also be used as a filter material in the wastewater treatment system for pretreatment of wastewater such as oil removal and solid impurity removal.
