A comparison between sulfuric acid and oxalic acid .

After acid leaching, most of the P-bearing minerals were dissolved, and the main mineral phases were quartz and hematite in the H 2 SO 4 leaching residue. A small amount of AlPO 4 still existed in the leaching residues, possibly because it is more soluble in an alkaline solution rather than in an acid solution (Li et al., 2018).
