The research achievement of using gold tailings to produce micro crystalline glass granite is presented.The research has shown that with gold tailings as the main raw material and by introducing CaO and MgO into it,CaO-Al 2O 3-SiO 2 seriers microcrystal glass can be formed.With this as the base and by adding various dyeing and add agents,microcrystal glass granite of various colours can be produced and their chemical and physical properties have reached those of natural granite and therefore, are a good ...
