Study on Preparation of Calcium Sulfate Whisker with Leaching Tailings of Nickel Ore

Abstract:

Taking leaching tailings of the nickel ore as raw material, calcium sulfate whiskers were prepared. The effects of Mg/Ca mole ratio, concentration of sulfuric acid, reaction temperature and precipitating time on the recovery of calcium were studied in this paper. The preparation method and reaction conditions of fibrous calcium sulfate whisker have been optimized by an orthogonal experiment, in order to obtain a high grade whisker product which could meet industrial requirements on whiteness and size.
