The water would then be filtered through sand tailings. The ultimate goal of schreuder's project is to inject the stored water into the Floridan Aquifer, because this is the least expensive water distribution system available. This would minimize evaporation and recharge the aquifer. Sand Tailings Phosphate processing leaves behind a lot of sand like these tailings that are being pumped into a mine cut. Phosphate is found in what is known as the matrix, which is a layer of Florida earth that contains sand, clay and phosphate.
Processing separates the phosphate from the sand and clay.
The sand, in conjunction with wetlands, could be a natural way to clean water stored in mine pits. The result could be a potable water source to help alleviate Florida's water worries. As Florida looks for alternative water sources, it also is trying to preserve what nature provides. Regulators require developers and others who destroy or damage wetlands or other parts of the state hydrological system to mitigate or relieve the impact with measures such as creating new wetlands. Among those who do a lot of mitigating are phosphate mining companies.
