After acidification wollastonite tailings

The present invention discloses a wollastonite tailings after acidification gist of the technical proposal is wollastonite tailings from the formulation after acidification tailings wollastonite, attapulgite clay, magnesium sulfate, sodium silicate instant, polyvinyl alcohol, hydroxypropyl methyl cellulose and sodium carbonate composition. The method of producing wollastonite tailings after acidification: wollastonite tailings ingredient after acidification input mill grinding, milling the powder after acidification wollastonite tailings. After acidification of tailings wollastonite, wollastonite can improve the utilization of tailings, will not only bring good economic, environmental and social benefits, but also turning waste into treasure. After acidification tailings wollastonite having good thixotropy characteristics of thermal stability, moldability, adhesiveness and dry high pressure. Wollastonite tailings after the acidification is suitable for production of environmentally friendly materials, building materials, blowing agents and fire protection products.
