The invention discloses a method for producing glass ceramics by using S95 ore slag powder as major raw materials. The method comprises the following steps of 1, raw material selection; 2, raw material mixing; 3, mixed material melting; 4, calendaring shaping; 5, annealing; 6, crystallization. The S95 ore slag powder is used as the main raw materials and can be used for producing the glass ceramics with various color series; the product compressive intensity is 250 to 300 MPa; the anti-bending intensity is 60 to 70 MPa. Rich calcium oxide contained in the ore slag can be used for preparing high-calcium glass ceramics; the raw material cost can be greatly reduced. Meanwhile, no coloring agent or a small number of coloring agents are contained in the ore slag; white glass ceramics can be prepared; various coloring agents can be added for preparing the glass ceramics in various color series such as red, blue and gray; in addition, the colors are stable. Many oxides for producing glass ceramics are contained in t
