Experimental investigation of phosphorus and potassium recovery from chicken manure incineration ash (CMIA) using a mixed nitric acid–oxalic acid system

Traditional acid leaching of chicken manure incineration ash (CMIA) often shows poor selectivity and may generate phosphogypsum. To address these limitations, this study developed a nitric–oxalic acid process for recovering phosphorus (P) and potassium (K) from CMIA with a high C...
