The phosphorus released under acidic conditions exceed that under neutral conditions by an order of magnitude.

•
The phosphorus was released faster during the period when environmental pH turned from weak alkalinity to slight acidity.
•
The phosphate waste rocks deposited within the Xiangxi River watershed could threaten the adjacent surface-water environment.
