A high belite sulfoaluminate cement clinker containing a magnesia-alumina spinel was prepared using industrial solid waste and high-magnesium limestone. The preparation procedure and the influence of the trace elements on the clinker were specifically investigated. This study reveals the mechanism of the clinker formation. The appropriate firing temperature of the clinker and holding time were determined to be 1300 °C and 60 min - 90 min, respectively. The presence of MgO and SO₃ displayed a positive effect on the clinker formation at high temperatures. In addition, the excessive MgO in the raw material was solidified to create the stable inertia mineral MgAl₂O₄, which eliminated the delaying expansion hazard of MgO.
