菱镁矿尾矿综合利用研究进展

我国菱镁矿储量、产量和出口量均居世界首位，同时菱镁矿开采加工过程中会产生大量尾矿。在概述菱镁矿尾矿矿物组成和化学成分的基础上，重点阐述菱镁矿尾矿在建筑材料（水泥、混凝土及膨胀剂、墙体材料、微晶玻璃）、耐火材料（镁砂、镁橄榄石、溅渣护炉改质剂）、化工产品（氧化镁、氢氧化镁、镁盐）和环保药剂（水处理剂、烟气净化剂、土壤修复剂）领域综合利用研究现状，指出菱镁矿尾矿综合利用领域存在的问题并针对未来发展提出建议。 

Advances in Comprehensive Utilization of Magnesite Tailings

The reserves, production and exports of China's magnesite rank first in the world, and thus producing a large amount of magnesite tailings during the development and utilization of magnesite mining. The mineral and chemical composition of magnesite tailings were introduced in outline, and the comprehensive utilization of magnesite tailings was summarized in detail, including building materials (cement, concrete, expansion agents, wall materials and glass-ceramics), refractories (magnesia, forsterite and converter protecting modifier for slag splashing), chemical products (magnesium oxide, magnesium hydroxide and magnesium salts), and environmental agents (water treatment agents, flue gas purifying agents and soil remediation agents). Furthermore, the existing problems were pointed out in the comprehensive utilization of magnesite tailings, and suggestions for its future development were put forward accordingly.
