【Abstract】 The east Mudanjiang zeolite ore deposits are located in the middle part of the regional deep fault zone of Dunhua Mishang. Ore bearing stratum,the Dongdaling formation (K 1 d ) of the Lower Cretaceous, mainly consists of flooding facies series with acid volcanic rocks (rhyolite and perlite,etc.).Zeolite minerals are clinoptilolite and mordenite in the deposits.There are 7 orebodies composed of the best quality zeolite ores,with the average ore grades ranging from 75.26% to 84.02%, the C.E.C of NH 4 + ranging from 1 640.6 to 1 831.7 mmol/kg, the C.E.C of K + ranging from 8.03 to 16.28 mg/g, the TG values ranging from 12.40% to 15.35%, temperatures of the thermal stability ranging from over 600 to 900℃, the acid resistant values ranging from over 10 to 12 mol/L HCl and the specific radiant entittances ranging from 0.82 to 0.91. It is certain that they are composed of the best quality zeolite ores which are uncommonly found in nature.更多还原
