How to deal with steel slag? What mineral processing equipment is needed?

Steel slag is a by-product of steel production and can be processed for various applications such as construction materials, road construction, and cement production. Here are some common steps and mineral processing equipment used for steel slag processing:

1. Crushing: Steel slag needs to be crushed into smaller size particles before further processing. Jaw crushers, impact crushers, and cone crushers are commonly used for this purpose.

2. Grinding: The crushed steel slag is ground into a fine powder using grinding mills such as Raymond mills, vertical roller mills, and ultrafine mills.

3. Magnetic separation: Magnetic separators can be used to separate the steel slag from iron particles.

4. Froth flotation: Froth flotation is used to separate metal ions and impurities from the steel slag.

5. Drying: The final product needs to be dried before being used in various applications. Rotary dryers or fluidized bed dryers can be used for this purpose.

Here is a table showing the approximate price range for some commonly used mineral processing equipment for steel slag:
