Resource utilization of Incineration slag

Resource utilization of Incineration slag

Incineration slag refers to a kind of solid waste generated in the process of Incineration, which is formed after the inorganic substances in the waste are burned at high temperature. Incineration slag contains a large number of inorganic substances, such as iron oxide, aluminum oxide, Calcium oxide and so on, which have high resource utilization value. This paper will introduce the resource utilization method and operation steps of Incineration slag.

1、 Resource utilization method of Incineration slag

1. Grind into powder

The Incineration slag is ground into powder, which can be used to manufacture cement, concrete and other building materials. The grinded Incineration slag has high activity, which can improve the strength and durability of building materials.

2. Extract metals such as iron and aluminum

Incineration slag contains a large amount of iron, aluminum and other metals, which can be recycled by extraction. There are various methods for extracting metals such as iron and aluminum, such as magnetic separation and leaching.

3. Manufacturing ceramic materials

Incineration slag contains a large amount of alumina, silica and other substances, which can be used to manufacture ceramic materials. The Incineration slag is grinded and screened, and then added with appropriate clay, quartz and other materials, which are made into ceramic materials through molding, drying, sintering and other processes.

4. Production of slag cement

Incineration slag contains a large amount of Calcium oxide, silicon oxide and other substances, which can be used to produce slag cement. The Incineration slag is ground and screened, and then appropriate gypsum, clinker and other materials are added to make slag cement through mixing, grinding, firing and other processes.
