Equipment for recycling aluminum from aluminum ore slag

Date: Mar. 22, 2022

The ash produced in the process of smelting ores is not actually garbage. Many ore ash can recover a considerable part of the minerals after being processed by the beneficiation ash production line. For example, aluminum ash is the remaining material after the slag is cooled during the extraction of aluminum alloys and bauxite. The main components are aluminum and silicon dioxide. After reprocessing, metal aluminum can be recovered.

The beneficiation ash production line includes beneficiation equipment, drying equipment and dust removal equipment

1. Grinding

Slag and ash beneficiation production line

Although it is ore ash, there are still many large particles in it, which need to be ground by grinding equipment. Generally, people will choose a ball mill.

2. Mineral processing
The pulverized materials are subjected to beneficiation. The beneficiation methods include flotation, magnetic separation and gravity separation. The ore particles are screened according to the physical and chemical properties of the materials.

Commonly used beneficiation methods include flotation, magnetic separation, and gravity beneficiation.

3. Drying

Concentrates that have undergone the beneficiation process cannot be sold immediately or used in the next step. They also need to be dehydrated. Commonly used drying equipment includes dryers, thickeners and dehydrators.

4. Dust removal
Many ore ash not only easily pollutes the environment, but also affects the health of workers. In order to solve this problem, most of the beneficiation ash production lines are mainly closed, and then equipped with dust removal equipment, such as bag filter, electrostatic precipitator, mechanical dust collector, cyclone dust collector, etc.
