Imagine an ideal place near an ideal sea port from where we could import phosphate rock and sulfur. To produce Phosphoric Acid (and its predecessor, Sulfuric Acid) at a rate of 200.000 tonnes of P2O5 a year, the fixed capital is supposed to be US$ 300 million in 2013.
The operating costs are: Phosphate Rock (at US$ 150 per tonne and 3 tonnes per tonne of P2O5), Sulfur (at US$ 80 per tonne and 1 tonne per tonne of P2O5), power, water, labor (may be 50 very skkilled personnel) and the disposal of gypsum.
Selling price is over US$ 1.000 per tonne of P2O5, but do the right calculations and you will see we are not making a lot of profity...
