We enrich potash ore using two methods: flotation and chemical (known as halurgic).
  • The halurgic method has been used since the potash industry started in the second half of the 19th century. It produces chemically pure MOP which contains 98% of the commercial component. This is used in agriculture and the chemical industry.
  • The flotation method has been used since the 1960s to produce potash fertilisers for agriculture, the products containing up to 95% of the useful component.
