2014-4-21 The phosphate is sent to a chemical processing plant, or fertilizer manufacturing plant. Here, molten sulfur, shipped to Florida ports and trucked to the plant, is used to create sulfuric acid. The sulfuric acid is then mixed with the phosphate to make phosphoric acid. The phosphoric acid is the main ingredient in fertilizer, but can also be used in animal feed supplements, soda, or soap.

2021-6-2 1. China — The country’s phosphate mining production decreased in 2018 to 140 million metric tons (MT) from 144 million MT in 2017, which is likely a result of Beijing’s environmental crackdown on the mining industry. There has also been speculation in the past that China’s phosphate production in 2017 may have been overstated.
