Process for producing artificial aggregate from mine tailings, artificial aggregate, concrete composition and use
The invention relates to a process for producing artificial aggregate from mine dam tailings. The method comprises the following steps: mixing iron ore tailing sand with an adhesive, and carrying out mixing and granulation to form the artificial aggregate. The produced artificial aggregate has spherical appearance, large particle size, rough surface and unequal color from pink to dark red. The artificial aggregate can replace natural aggregate, is used for manufacturing concrete with higher strength, is suitable for a base layer and a subbase layer of a road, can be used as a decorative element of a garden and a flower bed, and also can be used as a way for storing mine dam tailings in a pellet particle form, so that the value of the tailings is increased, and the influence of mining on the environment is reduced.
本发明涉及一种从矿坝尾矿中生产人工骨料的工艺。将铁矿尾矿砂与粘合剂混合，通过混合和造粒过程，形成人工骨料。这样生产出来的人工骨料具有球状外形，颗粒尺寸较大，表面粗糙，颜色从粉红色到暗红色不等。所述人工骨料可以取代天然骨料，用于制造更高强度的混凝土，适用于公路的基层和底基层，可作为花园和花坛的装饰元素，此外还可以作为一种以球团颗粒形式储存矿坝尾矿的方式，增加尾矿价值，减少采矿对环境的影响。
