2022 new product arrival! A production line for iron extraction and solid waste utilization from LONGi red mud tailings was developed successfully
Recently, LONGi red mud tailings iron extraction and solid waste utilization production line has been successfully developed and won a large customer order from a leading alumina enterprise in Hebei, with the order amount exceeding 20 million RMB, which has won the red mud tailings iron extraction solid waste utilization production line off to a good start!
The comprehensive utilization of red mud has always been a technical problem perplexing all countries in the world, and has gradually become a constraint factor for the green, circular and sustainable development of alumina industry.
It is estimated that the current red mud stock in China is about 600 million tons, with an annual increase of over 70 million tons. Almost all of the red mud is stored in the open air, posing a huge potential risk of environmental pollution.
As a leader in the magnetic equipment industry, LONGi is the main force to practice the efficient utilization of resources. With strong technical accumulation, LONGi has made a heavy attack and achieved the high-temperature magnetic separation of red mud pulp through a lot of experiments, and the production line for iron extraction and solid waste utilization of red mud tailings of alumina has come into being.
The production line perfectly adapts to the market demand and achieves a higher comprehensive recovery rate on the premise that TFe content is more than 60% qualified products.
The recovery rate leads the way, benefiting from LONGi's breakthrough in core technical barriers such as high temperature resistance and corrosion resistance of equipment.
For red mud pulp, LONGi drum magnetic separator increases the heat insulation layer, can deal with high temperature pulp of more than 80 degrees, and ensure that the magnetic field of the equipment is unchanged, the demagnetization rate is unchanged.
Enhance magnetic field intensity, reduce demagnetization rate, the recovery of fine particles greatly improved, amazing performance
With intelligent monitoring function, it can collect and analyze the running data in real time, and realize the independent judgment and alarm of the running state, with full "intelligence"
