It is the dream of generations of mines to recycle all the iron, titanium, vanadium and other elements in Panzhihua vanadium-titanium magnetite.
Today, the scientific and technical personnel of the Institute of Mining Research have built a bridge to connect dreams.
The industrial test of ultrafine ilmenite recovery undertaken by the institute has achieved good results recently, and it is expected to realize industrial application in the next two years.
The Panxi area is an important vanadium-titanium magnetite resource base and a vanadium-titanium industrial base in China.
The industrial recovery is generally carried out after the vanadium-titanium magnetite iron beneficiation, and then titanium resources are recovered from the iron tailings.
In actual production, in order to ensure a higher iron concentrate grade, a two-stage grinding stage selection process is often used.
However, after two stages of grinding, ilmenite over-grinding is inevitable in the iron dressing tailings, resulting in a substantial increase in the content of ultra-fine ilmenite (particle size less than 38μm).
At present, the usual method of beneficiation and recovery of ilmenite is to add desliming operations before and after flotation to remove the sludge.
But the sludge removed is actually an ultra-fine material with a particle size below 38μm.
These ultra-fine particles also contain high-grade ultra-fine ilmenite that can be used for flotation.
In order to increase the recovery rate of titanium resources, the Institute of Mining and Research has been working on the technology of recovering ultrafine ilmenite from 2012.
After a large number of experiments, a cost-effective and efficient process for the recovery of ultrafine ilmenite has been explored, and 3 national invention patents have been authorized.
At present, the research and development team of the institute is strengthening the industrial test and research of ultrafine ilmenite recycling while doing a good job of technical protection, to determine the economical and efficient ultrafine ilmenite beneficiation process and industrialization, and improve the comprehensive titanium resources.
Recycling and utilization levels, and earnestly promote technological benefits.
