Title:
METHOD FOR PROCESSING OIL COMBUSTION ASH
Document Type and Number:
WIPO Patent Application WO/2018/211996
Kind Code:
A1
Abstract:
This method for processing oil combustion ash includes: a slurry production step (S10) for adding water to oil combustion ash containing vanadium and nickel to produce a combustion ash slurry; a magnetic separation step (S20) for magnetically sorting the combustion ash slurry to thereby separate the combustion ash slurry into magnetic material containing vanadium and/or nickel and a magnetic-material-separated slurry; a solid-liquid separation step (S30) for separating the magnetic-material-separated slurry into an aqueous solution and solid content; and a vanadium-nickel separation step (S40) for separating vanadium and/or nickel from the aqueous solution.
