Environmental impacts caused by phosphate mining and

2014-5-8  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

World’s Top 10 Phosphate Mining Production Countries

2020-3-14  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.
