İri ve ince tesis atıklarından kromit kazanım olasılıklarının incelenmesi
Year 2022, Volume 61, Issue 2, 69 - 81, 26.06.2022Abstract
Mevcut bir kromiti zenginleştirme tesisi atık akışları, farklı yöntemlerle karakterize edilmiş ve zenginleştirilmiştir. Karakterizasyon çalışmaları, kromit taneciklerinin tüm boyut fraksiyonlarında (+100 µm) iri yantaş taneleri üzerinde ince bir şekilde dağıldığını göstermiştir. iri atık zenginleştirme çalışmaları sırasında incelikteki artış, saçınımlı kromit tanecikleri üzerinde önemli bir etki göstermemiştir. İri atıktan ne satılabilir bir konsantre ne de kabul edilebilir bir verim elde edilememiştir. Bu nedenle optimizasyon çalışmaları ince atık numunesi üzerinde yoğunlaşmıştır. Yantaş minerallerinin uzaklaştırılmasında yerçekimi ile zenginleştirmenin manyetik ayırmadan daha verimli olduğu belirlenmiştir. Sallntılı masa parametrelerinin etkisi ampirik modeller kullanılarak optimize edilmiştir. Konsantredeki tenör ve verimin önemli ölçüde masa eğimindeki değişime bağlı olduğu belirlenmiştir. Yüksek tenör (>%42) ve kabul edilebilir bir verim (>%40) elde etmek amacıyla, orta seviyede yıkama suyu (>4l/d) ve düşük seviyede masa eğimi (<3 derece) gereklidir. Ampirik modellerin geçerliliği, y=x doğrusu üzerinde ölçülen ve tahmin edilen değerlerin iyi bir uyumla sonuçlandığı bir dizi test ile doğrulanmıştır.

Investigation of chromite recovery possibilities from coarse and fine plant tailings
Year 2022, Volume 61, Issue 2, 69 - 81, 26.06.2022Abstract
Tailing streams of an existing chromite plant were characterized and then beneficiated in different methods. Characterization studies have been indicated that chromite grains finely disseminated on the coarse gangue particles in all size fractions (+100 µm). Increase in fineness did not show a significant effect on disseminated chromite grains during coarse tailing beneficiation studies. Neither a salable concentrate nor an acceptable recovery could not be obtained from coarse tailing. For this reason, optimization studies were focused on fine tailing sample. Removal of the gangue minerals was determined to be more efficient using gravity concentration rather than magnetic separation. The effect of parameters of shaking table were optimized using empirical models. It was determined that grade and recovery in the concentrate majorly depended on the variation of table slope. To achieve high grade (>42%) with acceptable recovery (>40%), a medium level of wash water (>4lpm) and lower level of table slope (<3 degree) is necessary. Validation of the empirical models were verified with set of tests which measured versus predicted values resulted good agreement on the y=x line.
