Characterization of size‐specific effects during dual‐energy …
Errors in calcium concentration (mg/ml) for three concentrations of calcium; 50, l00, and 300 mg/ml. Errors were calculated from Dual Spiral contrast images calculated with the Syngo software LiverVNC application using eight workflows applying different variations of beam hardening correction (BHC) activation and dual‐energy ratio …

Modeling and Optimisation of Spiral Concentrator for
Experiments were carried out using a spiral concentrator test rig containing feed conditioner, centrifugal pump and a spiral concentrator with feed to spiral and recirculation. Time samples of concentrate and tails were collected, weighed, dried analysed. Regression equations were developed for Concentrate yield, grade and …

Spirals in Australia mineral processing
Spiral concentrators are used in mineral processing for separating minerals. Multotec Australia has a range of gravity concentration equipment for effective mineral concentration. The range comprises end-to-end spiral solutions, from process audits and test work, to complete spiral concentration plants optimised for your specific process.

An operational model for a spiral classifier
The quadratic model showed higher performance values on the training set; however, the extended Holland-Batt model showed better performance on the test data. Finally, both models were compared in terms of spiral concentrator plant modelling ability (based on an industrial spiral concentration plant).

The six main steps of iron ore processing
This step is repeated two or three times, depending on the desired liberation and iron concentration. 6. Magnetic separation The concentrate collected from the middlings and tails after spiral gravity separation has a lower iron concentration (magnetite) so it must be further concentrated to achieve the customer's 65% Fe concentration. It is ...

Principles of spiral concentration
Furthermore, the experimental and numerical simulation of the separation of quartz and hematite were performed in a laboratory-scale spiral separator. When the Bagnold lift force model was considered, predictions of the grade of iron and solid concentration by mass for different trough lengths were more consistent with …

Gravity Spiral Concentrator Working Principle
For the spirals to work efficiently the feed supply must have consistent characteristics and be of a constant rate. Variations in the flow rate, the feed size distribution, and percentage solids will have adverse effects upon separation. Generally, the solids tonnage should give …

Tailings valorization and iron recovery from spiral
Study showed an anomalous concentration of iron oxides in the finer fractions of tailings (<106m) due to spirals intrinsic inefficiency. This material presents considerable Fe …

Size recovery curves of minerals in industrial spirals for …
The mineral size recovery curves show that the rougher spiral recovery of iron carrier particles finer than 0.075 mm is less than 50%. Recovery of the iron carrier …

Evaluating separation efficiencies of Multotec's new …
The slurry was fed to the spiral via a distributor with an overflow pipe to maintain a constant feed rate into the spiral. This was a closed-circuit spiral test with a sump and pump. During each test, the spiral was run until steady-state conditions were reached before taking the relative density (RD) measurements at the top of the spiral rig.
