Anilite: Mineral information, data and localities.

All specimens studied by the authors of the original description contained some djurleite. Note: Many of the reported associations of digenite and djurleite, identified by powder diffraction, could be anilite and djurleite, as anilite transforms to digenite during grinding (Goble, 1985). If heated, anilite decomposes to high digenite and covellite above 70 +- 3°C (Morimoto & Koto, 1970).

Adjustment of Olive Fruit Temperature before Grinding for ...

Harvesting at high temperatures and bulk transport can negatively influence the quality of olives and lead to undesirable alterations in the extracted oil. Cooling the fruit in the field would be the most logical solution, but it means that the olives arrive too cold at the mill for immediate processing. In this work, the use of warm water in the washing tub to warm up the fruit before ...
