摘要

沂南金尾矿钙含量高，硅铝含量低，是众所周知的难烧结砖。在分析其基本性能的基础上，研究了用其压制成型制取烧结砖。结果表明，最佳工艺体系为:成型压力15MPa，成型含水量8%~9%，烧结前含水量1%，烧结温度1050℃，保温时间60min。采用该处理方法，75%细尾砂和25%中尾砂的砖抗压强度可达MU10。

Research on Making Fired Bricks with Gold Tailings

Yi Nan Gold tailings are well known as difficulty to make fired bricks due to their high content of calcium and low silicon¡ªaluminum content. Based on the analysis of their basic properties, research has been taken on using them to make fired bricks by press forming. The results indicated that the optimum technology system was: forming pressure 15MPa, forming water content 8%~9%£¬water content before sintering 1%, sintering temperature 1050¡æ, holding time 60minutes. By applying this treating methodology£¬the compressive strength of the brick with 75% fine tailings and 25% medium tailings can reach MU10.
