ChinaMorocco and Western SaharaUnited StatesRussiaJordanBrazilSaudi ArabiaEgyptIsraelVietnam and TunisiaMine production: 140 million MTChina’s phosphate mining production decreased in 2018 to 140 million metric tons (MT) from 144 million MT in 2017. The drop in Chinese output is likely a result of the country’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. According to industry analysts, the country produced just 85 million MMeer bekijken op investingnews

Phosphorite Wikipedia

Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock which contains high amounts of phosphate minerals.
