Iron tailing solidification treatment method
The invention provides an iron tailing curing treatment method, and belongs to the technical field of tailing curing. The iron tailing curing treatment method comprises the following steps: uniformly mixing iron tailings, desulfurized fly ash and water to obtain a mixture; and carrying out compression molding on the mixture, and controlling process parameters of compression molding to obtain a cured body. After the iron tailings are solidified, the solidified body which can be stacked and is friendly to the environment is produced, and the iron tailings can be rapidly solidified on a large scale and subjected to resource utilization. A special tailing pond does not need to be built, and the desulfurized fly ash with extremely low cost is used as a curing agent, so that the curing cost is further reduced, and large-volume tailing curing work is facilitated. The solidified body obtained by the invention can be suitable for safety reclamation with various strengths, and the problems of high cost and high carbon dioxide emission due to the fact that cement is used as a solidifying agent for traditional tailings are solved. Therefore, the technical problems of high cost, low efficiency and low curing strength of the existing iron tailing curing treatment are solved.
本申请提供了一种铁尾矿固化处理方法，属于尾矿固化技术领域。所述铁尾矿固化处理方法包括：将铁尾矿、脱硫灰以及水混合均匀，得到混合体；将所述混合料压制成型，并控制所述压制成型的工艺参数，得到固化体。本申请将铁尾矿固化后，生产出可堆放的、对环境友好的固化体，可以快速地、大批量地对铁尾矿进行固化并资源化利用。无需建造专门的尾矿库，并使用成本极低的脱硫灰作为固化剂，进一步降低固化成本，有利于大体积尾矿固化工作。本申请得到的固化体可适用于各种强度安全复垦，并且避免了传统尾矿用水泥作为固化剂成本高和二氧化碳排放高的问题。从而解决了目前现有铁尾矿固化处理存在的成本高、效率低以及固化强度低的技术问题。
