尾矿变身绿色建材
2017-08-21 06:11:37 中国青年网
本报讯 记者雷汉发、通讯员贾建勇报道:8月上旬,记者在河北宽城满族自治县看到了神奇的一幕:一车车铁矿尾矿通过精细分选、加工等一系列工序后,变成了结实美观的微晶石系列产品。“我们每年利用尾矿37万吨,利用率达70%。生产微晶玻璃、玻化砖、泡沫玻璃、免烧砖、空心砌块等一系列产品,不仅供应国内大中城市,还出口欧美等国。企业全面投产后,预计年营业收入9.5亿元,年均利润总额1.7亿元。”河北承德新通源新型环保材料有限公司负责人说。
新通源公司发展新兴产业,变废为宝,正是承德综合利用尾矿资源打造“新型建材及住宅产业化示范基地”的一个样本。承德市有871座尾矿库,累计存积量25亿吨。2015年8月份,承德率先在全省全部关闭了186家黏土砖生产企业,确定了平泉天罡、承德德厦、承德新通源等10个龙头企业,重点打造“十大绿色产业”。
2016年,全市尾矿综合利用实现产值近160亿元,年消纳尾矿5500万吨。2016年9月份,承德被工信部确定为全国12个工业资源综合利用示范基地之一。截至目前,承德累计实施尾矿综合开发利用项目110个,涵盖墙体材料、保温材料、路面材料、装饰材料等十大系列50多种产品,形成了研发、制造、销售的完整产业链条。
承德市工信局相关负责人介绍,承德力争到2020年全市新排尾矿综合利用率达100%,存量尾矿利用率达40%,实现尾矿利用相关工业产值千亿元,利润百亿元。
