“…Such conditions can only be provided by trough geometry, optimum operating parameters. The main operating parameters are feed flow rate, feed pulp density and splitter position which influence the performance in the process [29][30]. Fine mineral spiral separators are used to treat particles down to 30 micron size [28].…”

“…In most research, the particle size distribution of the feed is made constant throughout the experiment. However, insufficient global research on optimizing the spiral concentrator's efficiency in sand processing is the main reason this industry has underutilized spirals [15,16]. Therefore, the current study investigates the role of three critical parameters on the efficiency of the spiral concentrator in the processing of silica sand.…”

The main aim of this study on silica sand using a spiral concentrator using the design of experiments DOE) approach is to improve the silica content of the tailing sand for the glassmaking process. Three significant operational parameters of the spiral concentrator, namely feed rate (t/h), solid feed (wt.%), and splitter position (cm), were investigated to observe their effects on the SiO2 grade (%) and recovery of SiO2 (%) in the middlings using Design of Experiments (DOE). The raw sample was sieved to prepare the feed sample in the size range of -600+75µm, which was the suitable particle size range for the glassmaking process. The SiO2 grade (%) of each middling fraction from 33 test runs was determined from XRF analysis. The analysis determined that the feed rate and weight of the solid feed (wt.%) significantly affected the separation, while the splitter position in the investigated range (4.5-5.5cm) showed a negligible effect on the percentage and recovery of SiO2 in the middling fraction. It was observed that a maximum SiO2 grade of 94.98% was achieved at a solid feed of 25%, feed rate of 0.63 t/h, and splitter position of 5.5cm. The highest SiO2 recovery of 89.74% was achieved at the solid feed of 15%, feed rate of 0.45t/h, and splitter position of 5.0cm. A trade-off between the optimized results for SiO2 Grade (%) and recovery of SiO2 (%) responses using overlaid contour plots suggested a feed rate of 0.58 t/h of feed rate and 25 wt. % solid feed regardless of the splitter position. The customized range of parameters is expected to produce 94.51% SiO2 grade (%) and 80.11% recovery of SiO2 in the middling fraction.

In the present investigation, an attempt is made to synergize the effects of textural, physical and chemical characteristics of placer deposits. These deposits are associated with lean and off-grade placer heavy minerals, which typically exhibit variations in total heavy minerals, texture and composition. They are found all along the coastal stretch of the Bay of Bengal, from Chatrapur to Puri Dists, Odisha, India. The aim is the recovery of total heavy minerals using various models of gravity concentrates. The results of the present study reveal that the Mozley table produced a concentrate containing 93.2% THM. In comparison, the gravity table, HG8 spiral, CT spiral and Humphrey spirals yielded concentrates with 92.2%, 92.9%, 93.6%, and 98.2% THM, respectively, from a feed sample containing 4.72% THM. Additionally, it was observed that the performance of the spiral depends on both the feed grade and the texture analysis of the input material.
