Gypsum Mining In Nigeria The Prefeasibility Report

About one billion tons of gypsum deposits are spread over many sites in Nigeria. The quality of gypsum is a function of the calcium sulphate CaSO4 content. The higher the calcium sulphate CaSO4 content, the higher the grade and price. This report seeks to examine the financial viability or otherwise of mining gypsum rock in Nigeria.
