Abstract
Magnesite is the world’s most important source material for magnesia refractory production and Haicheng City in Liaoning Province China has been called “the magnesium capital of the world” However magnesite mining in these areas has caused serious environmental problems Field investigations have shown that the soil profile of many sites in the mining region are contaminated by magnesium and the magnesiumenriched crusts that have formed on the soil surface have affected ecologically important soil functions particularly reduced water penetration rate Laboratory experiment revealed that anionic polyacrylamide and calcium dihydrogen phosphate can be used to improve soil condition and have positive effects on soil function The findings of this study are of significance in the magnetite mining areas providing clear options for the remediation of soils that should be carried out immediately
