“…The number of operations and intensity of magnetic separation have a significant impact on the removal of iron impurities. The commonly used magnetic separation equipment includes wet high-gradient magnetic separators and dry high-gradient magnetic separators [20]. Ran and Zhang [21] utilized a two-stage dry high-intensity magnetic separation operation to reduce the Fe 2 O 3 content of the product from 20 ppmw to 2 ppmw.…”

Iron is one of the most stubborn impurities in quartz minerals, and the iron content partly determines the various applications of quartz. Iron can exist in quartz in the forms of iron minerals, fluid inclusions, and lattice impurities. The removal of iron and the consequent purification of quartz minerals are the key processes to obtaining high-quality quartz. Iron removal methods including conventional pre-treatment, magnetic separation, acid leaching, microbiological, roasting, and flotation, as well as combined iron removal methods in quartz ore, are herein summarized. The separation mechanism of quartz and iron impurities and the latest research progress were explained and summarized, and the development prospects of quartz purification in the future were proposed based on the current progress and limitations of quartz iron removal.

In this research article, design and fabrication of material separation machine is discussed with the objective to decrease the time, money, and labor required to separate waste materials from one location to another, the design and manufacture of material separation machines are explored in this study. The fundamental concept was inspired by the development and application of artificial intelligence as well as the motion of robotic arms. The Material Separation machine's design places an emphasis on separating recyclable and usable waste from the accessible trash while using less energy and scientific approaches to separate the valuable material. The device is helpful for the efficient use of time and human labor, as well as for areas where a lack of manpower is a concern. Compared to other existing Material Separation machines, our machine utilizes cheap, readily available materials in the best way possible to produce an effective outcome in a predetermined amount of time.

“…Therefore, it is essential to investigate ways to enhance the value of these tailings. Many methods have been reported trying to utilize these titanium tailings, including enhanced gravity separation (Zeng et al, 2017), flocculation (Fan et al, 2020), self-carrier flotation (Zhu et al, 2011), and wet high-intensity magnetic separation (Hu et al, 2023). Although specific studies demonstrated potential in recovering the ultrafine ilmenite from these tailings, they face lower throughput difficulties, production cost problems, and environmental issues pending industrial applications (Zhai et al, 2020).…”

In southwest China, the Panzhihua area annually produces about 80 million tons of tailings with a TiO2 grade of around 5.0%, which causes serious waste of titanium resources as well as environmental and safety issues. The ilmenite contained in these tailings is ultra-fine in size, so it is difficult to recover under the regular operating conditions of pulsating high gradient magnetic separation (PHGMS). In this study, an SLon-100 PHGMS separator was applied to concentrate an ultra-fine titanium tailing under a wide range of operating conditions. The experimental results indicated that a combination of high pulsating frequency, large pulsating stroke, and low feed velocity was favorable for the highly efficient recovery of ultra-fine ilmenite from the tailings. The TiO2 grade in the optimal concentrate was enhanced from 4.33% to 13.64%, at a recovery of 66.55% and an enrichment ratio of 3.15 through a one-stage PHGMS process. The size analysis of the optimal concentrate showed that the TiO2 recovery in -25+18 µm and -18+10 µm fractions exceeded 70%. To further understand this PHGMS performance, the optimal ultra-fine ilmenite and larger-size ilmenite concentration conditions were compared. This study provides a valuable reference in the PHGMS operation for recovering ultra-fine weakly magnetic minerals, including ilmenite.
