2013-9-11 A typical phosphate mining operation can produce between 180,000 and 225,000 gallons per minute of fine phosphatic clay tailings. This material has a solids concentration of between 2% and 7% on a dry-solids basis. Currently, ponds and lagoons are used for settling and clarification of these materials.

Read MorePhosphate mining in Florida yields waste products of phosphatic clay and quartz sand tailings. Phosphatic clay ponds typically occupy about 50% of the mined sites and normally require 10 to 15 years before 40 to 50% solids are obtained. These clays contain no phytotoxic materials, and are high in most plant nutrients; when surface water has disappeared they are classified as clayey Haplaquents....
