An investigation into processing fine magnetite using a magnetic hydrocyclone
Bibliographic record
Abstract
As a consequence of fine grinding in the mineral processing industry, fine material containing quantities of valuable metal is being lost to tailing dams, wastewater and mine drainage. The processing of ultrafine particles has always been a challenge in the mining industry, thus typically, fine components are often considered waste during mineral processing. In addition, magnetic adsorbents are also being investigated as a method of processing wastewater, leading to the need for methods of recovering fine material post adsorption. A method of fines recovery, using a magnetic hydrocyclone to increase ultrafine and fine (−38 µm) material recovery from slurry was investigated in this paper. The attached permanent (Nd-Fe-B) magnet concentrated magnetite particles to the underflow and increased recovery by 15.4%, 5.6% and 2.0% on average for ultrafine (<5 µm) magnetite and two size distributions of fine magnetite (<38 µm), respectively, when compared to a conventional hydrocyclone.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
