Process for producing magnesium oxide from alkaline fly ash or slag |
| abstract |
The invention provides a process for producing magnesium oxide from fly ash or slag comprising magnesium and iron, the process comprising: leaching the fly ash or slag with an aqueous mineral acid solution to produce a leaching solution and a residue, the leaching solution comprising a magnesium salt and an iron salt; precipitating the iron salt by increasing the pH of the leaching solution to above 3.5, and separating the leaching solution from the precipitated iron salt; and forming magnesium oxide by decomposing the magnesium salt present in the leaching solution. |
