摘　　要：为解决黄金行业氰化尾渣大量堆存问题,实现高硅尾渣大宗利用,在前期实验室小型试验成功的基础上,开展了以高硅尾渣为主要原材料生产欧式连锁陶瓷瓦的中试试验研究。结果表明:在烧成温度1100℃、烧成时间56 min条件下,可实现高硅尾渣掺量高达70%的陶瓷瓦烧成,且成功解决了产品黑心、变形等质量问题,吸水率与强度等指标均满足GB/T 21149—2007《烧结瓦》中Ⅱ类烧结瓦要求。该技术实现了高硅尾渣的无害化、资源化、产品化利用。To address the problem of large-scale cyanide tailings storage in the gold industry and achieve bulk utilization of high-silicon tailings,a pilot test was conducted based on previous successful small-scale laboratory experiments.This study focused on producing European-style interlocking ceramic tiles using high-silicon tailings as the primary raw material.The results indicated that,under firing conditions of 1100°C and a firing time of 56 min,ceramic tiles with up to 70%high-silicon tailings content could be successfully produced.This approach effectively resolved issues related to black core and deformation,meeting the standards for water absorption and strength set out in GB/T 21149-2007 for TypeⅡsintered tiles.This technology realizes the harmless,resource-based,and product-oriented utilization of high-silicon tailings.
