Abstract

In order to suggest recyling and handling method of a tailing, observe it's physical and chemical properties, make an quality test of aggregates which are used a tailing and then examine a applied possibility in architectural materials. Tailing has a ununiform and many-side shape and it is organized quartz, muscovite, calcite, montmorillonite. pH is 6.86-7.28 and the result of leaching test is that Hg and Pb exceed of a standard. The specific gravity of aggregates which are used tailing is 1.95-2.23 and the absorption factor is 9-14.67%. The result of test for abrasion and crushing of aggregates which are used BFS is very excellent. The heavy metal is stabilized but a eruption property of Hg is similar to original sample.
