Over 90 percent of global potash production is used for plant nutrition. Canada is currently the world's largest producer and exporter of potash. Potassium chloride (KCl) accounts for most of the potassium used in world agriculture (about 90 percent). ... Boring machines cut wide tunnels to extract ore from the rock deposit. A mine can have ...

High-grade polyhalite is directly used as a potash fertilizer after being mined and crushed.7 For low-grade polyhalite resources that can be easily exploited, the roasting−hot leaching method can be used to extract potassium. However, the burial depth of polyhalite resources in the Sichuan Basin is relatively large.
