Phosphorite

In addition to fertilizers, the phosphate minerals derived from phosphorite are utilized in flame-retardants, insecticides, fireworks, and a plethora of other products. Phosphates have also been heavily utilized in detergents, but have become less popular for this purpose over the last few decades. The reason for the decrease in demand of phosphate-based detergents is primarily due to mounting evidence that phosphates interfere with the natural balance of water bodies, causing eutrophication and algal blooms. Yet, it is not universally agreed that the primary means of phosphate entry into waterways is through effluent containing detergents. Many scientists believe that fertilizer run-off may be equally culpable of polluting waters.
