· Similar to other products of the plantation, widespread use of phosphate is accompanied by environmental destruction. Phosphate strip mines produce around 150 million tons of toxic spoil a year, and the ravaged exterior edges of key mining zones—marked by massive draglines, huge slurry pipes, and heaps of waste—are visible for tens of miles.
phosphate minerals (dominantly apatite) were obtained from the underflow product. The superior adsorption of cationic surfactants on silica rather than apatite probably can be attributed to the more negatively charged surfaces of silica [5]. The conventional Crago double float process is used to remove silica twice from phosphate ore in Florida.
