Abstract

Abstract

Lightweight porous ceramic materials is prepared from flotation tailings of a typical porphyry copper ore in Mongolia, albite, kaolin and foaming agent SiC. The effects of material ratio, grinding time, foaming agent type, foaming agent dosage and sintering temperature on the apparent density and compressive strength of lightweight porous ceramics are studied by orthogonal tests. When the ratio of m (copper tailings)∶m (albite)∶m (kaolin) is 6.4∶2.7∶0.9, the grinding time was 15min, the content of foaming agent (SiC) was 0.1%, the sintering temperature was 1180℃ and the holding time was 60min, the technological process was the best. At this time, the apparent density of porous ceramic material was 580 kg/m³, the compressive strength was 4.90 MPa and the softening coefficient was 0.92.
