There's not much that can be done with it because essentially (not basically) it is ,acid,. Phosphate mining uses sulfuric ,acid, to extract the phosphates. These are large scale operations and produce a lot of water with a pH of 1.5-2. There's no comparable industrial process that can consume it as input. So it sits.
