The invention discloses a method for producing mineral
slag micropowder by using
titanium extraction
tailings in the technical fields of
solid waste treatment and
resource utilization. The method mainly comprises the following steps: firstly preparing a
liquid phase activating agent, performing
liquid phase activation on
titanium extraction
tailings by using the activating agent, performing
dehydration on the activated
titanium extraction
tailings, performing crushing, performing
calcination, and finally
grinding the obtained tailings to obtain the mineral
slag micropowder. The method providedby the invention has the following beneficial effects: firstly,
liquid phase activation is performed on the titanium extraction tailings, so that very good dechlorination and
decarburization effectscan be obtained at a lower
calcination temperature, and at the same time, potential hydration activity of the titanium extraction tailings can be well maintained; then low-temperature
calcination is performed on the titanium extraction tailings, and
grinding is performed, so that the S95-grade mineral
slag micropowder can be prepared, and the mineral slag micropowder is used in a project or sold;and the method has the advantages of high dechlorination efficiency, low
treatment costs, a large
processing amount, a short process, good
environmental protection and a good energy saving effect, andthe product has certain added value and large market capacity, and is a very good path for large-scale consumption of the titanium extraction tailings.
