Phosphorite Is Selected From Iron Tailings

Turn waste into treasure: phosphate ore from iron tailings, open a new chapter in resource recycling!

With the depletion of mineral resources and the increasing awareness of environmental protection, how to effectively use resources and reduce environmental pollution has become a major issue facing the mineral processing industry. Iron tailings, as the main solid waste produced in the process of iron ore beneficiation, have long been regarded as "chicken ribs", and their massive storage not only occupies land resources, but also has potential environmental risks. However, these seemingly useless iron tailings actually contain valuable phosphorus resources.

Phosphorus extraction from iron tailings: a green choice for resource recycling

Iron tailings in China are quite large, and generally contain a certain grade of phosphate minerals. Choosing to recover phosphorus resources from iron tailings can not only alleviate the shortage of phosphate resources in China, but also effectively reduce the environmental pressure brought by iron tailings storage, and achieve a win-win situation of economic and environmental benefits.

Effective phosphorus selection process: tailored, accurate recovery

In view of the occurrence and interlock of phosphate minerals in iron tailings, Henan Zhengkuang Machinery Co., Ltd. has developed a set of effective and environmentally friendly phosphorus separation process for iron tailings, which mainly includes the following processes:

Crushing and screening: The crushing equipment is used to crush and screen the iron tailings to obtain the selected materials with appropriate grain grade.

Grinding classification: The ball mill is used to fine grind the material to dissociate the phosphate minerals, and the fineness of the grinding is controlled by the classifying equipment to create favorable conditions for subsequent flotation.

Flotation separation: The flotation machine is used to achieve effective separation of phosphate minerals and gangue minerals by adding specific flotation agents, and high-quality phosphorus concentrate is obtained.

Core equipment: outstanding performance, stable and reliable

Ball mill: The use of advanced design concept and manufacturing process, with large processing capacity, high grinding efficiency, low energy consumption characteristics, can effectively ensure the fineness and uniformity of grinding products, create favorable conditions for subsequent flotation.

Flotation machine: with unique impeller structure and aeration mode, it has the advantages of uniform bubble dispersion, good mineralization effect and high flotation efficiency, which can effectively improve the grade and recovery rate of phosphorus concentrate.

Mixing tank: made of wear-resistant and corrosion-resistant materials, it has the characteristics of uniform mixing, stable operation, long service life, etc., which can effectively ensure the dispersion of flotation agents and the uniform stability of pulp.

Environmental protection and economy: the two prongs together, the benefit is remarkable

Environmental benefits: The process can effectively recover the phosphorus resources in iron tailings, reduce the stock of tailings, reduce the risk of environmental pollution, and have good environmental benefits.

Economic benefits: The process has low investment cost and low operating costs, which can create considerable economic benefits for enterprises.

Our company focuses on providing comprehensive solutions, from process design, equipment manufacturing to installation and commissioning and follow-up technical support, to ensure that each beneficiation production line can run stably.

With its strong performance, high reliability equipment, as well as the continuous pursuit of environmental protection and energy saving technology, our company not only improves the utilization of mineral resources, but also helps customers achieve a win-win situation of economic benefits and environmental protection.
