Triple superphosphates (TSP) are produced by reacting ground phosphate rock with phosphoric acid. Triple superphosphate is also known as double, treble, or concentrated superphosphate. The phosphorus content of triple superphosphates is over 40%, measured as phosphorus pentoxide (P 2 O 5 ), which is its main advantage over other phosphatic fertilizers.

This paper presents the environmental impacts caused by surface mining and the ecological rehabilitation of Haikou phosphate deposits, Kunming, China. Surface mining entails the removal of the overburden to expose bare rock surfaces, not only causing destruction of pre-existing vegetation, but also occupying large areas of land for dumping the spoil. Severe environmental impacts are caused, e ...
