Solid waste lithium slag and treatment method and application thereof
The invention relates to a treatment method of solid waste lithium slag. The treatment method comprises the following steps: A1, treating lithium slag by adopting a dilution and neutralization method; a2, the lithium slag treated in the step A1 is subjected to desulfurization, dehydration and drying through a heat treatment chemical replacement method; a3, after the lithium slag treated in the step A2 is vertically milled to a certain particle size through a vertical milling system, an exciting agent is added, and the volcanic ash activity of the lithium slag is excited; and step A4, adding a grinding-aid water reducing agent into the lithium slag excited in the step A3, and grinding until the required particle size is reached, so as to obtain a finished product. A dilution neutralization method and a heat treatment chemical replacement method are adopted, and a grinding-aid water reducing agent and an exciting agent are introduced in a grinding stage, so that the lithium slag is adjusted in a unified available specification range, the lithium slag does not have strong adsorption force to water, and the volcanic ash activity is fully activated, thereby solving the problem that the lithium slag serving as a mineral admixture is added into the concrete, and the service life of the concrete is prolonged. The performance of the concrete is reduced; and large-scale production cannot be formed.
本发明涉及一种固废锂渣的处理方法，包括以下步骤：步骤A1：对锂渣采用稀释中和法进行处理；步骤A2：对经过步骤A1处理的锂渣采用热处理化学置换法脱硫、脱水干燥；步骤A3：对经过步骤A2处理的锂渣使用立磨系统立磨到一定粒径后，加入激发剂，激发锂渣的火山灰活性；步骤A4：对经过步骤A3激发的锂渣加入助磨减水剂进行粉磨，粉磨至要求粒径，即得成品。本发明通过采用稀释中和法和热处理化学置换法，并在研磨阶段引入助磨减水剂和激发剂，使得锂渣调整在统一可用规格范围内，对水不具有强吸附力，火山灰活性被充分激活，从而解决锂渣作为矿物外加剂加入混凝土中，导致混凝土性能下降以及无法形成规模化生产的问题。
