Iron tailings can be processed into building materials, etc., and processed by crushing, screening, grinding and beneficiation equipment. There is a broad prospect for reuse, and it can be used for sand and gravel aggregates, cement, etc., to improve resource utilization, achieve economic and environmental benefits, and promote green economy and sustainable development.

Iron tailings are solid waste generated after iron ore beneficiation, and have rich reuse value. The cumulative amount of iron tailings stored in my country is as high as 1.5 billion tons. Through reasonable development and processing, it can effectively alleviate resource pressure and achieve economic and environmental benefits.

Detailed explanation of iron ore crushing and processing equipment

Iron tailings processing process

According to the characteristics of iron tailings and the demand for finished products, a variety of equipment such as crushing, screening, grinding and beneficiation can be used for processing. The specific steps are as follows:

The first stage: crushing and screening

Large-size tailings are initially crushed using jaw crushers, cone crushers or sand making machines, and small-size tailings can be pre-screened with vibrating screens and then finely crushed.

The second stage: magnetic separation

The crushed tailings are separated from iron ore using magnetic separation equipment, and the remaining tailings can be used for building materials or further processing.

The third stage: grinding

Depending on the purpose, the tailings can be ground to a suitable fineness using equipment such as ball mills to make building materials or used in industries such as cement.

The fourth stage: sorting

Tailings containing valuable metals are sorted to improve resource recovery.

Introduction to main equipment

Vibrating feeder: suitable for feeding before crushing and screening.

Jaw crusher: used for medium-sized crushing of ores and bulk materials.

Magnetic separator, ball mill: used for metal sorting and grinding processing respectively.

Reuse prospects and applications

Iron tailings can be processed into high-quality sand and gravel aggregates, replacing natural sand for engineering construction, improving resource utilization, and complying with the concept of sustainable development. Tailings sand has important applications in high-demand projects due to its anti-corrosion properties. For example, the tailings sand used in the "Shenzhong Channel" project has excellent durability. In addition, iron tailings can also be used to produce cement, concrete aggregates and a variety of building materials, creating considerable economic benefits.

Tailings reuse needs to go through crushing, sand making and screening processes. The initial crushing is done by jaw crusher, and the subsequent fine crushing and shaping are completed by sand making machine, and finally the finished product is graded and inspected by vibrating screen.

The reuse of iron tailings is an environmental protection project that benefits the country and the people, which can significantly reduce resource waste and achieve green economy and sustainable development.
