Alumina Crusting and Dissolution in Molten Electrolyte
Summary The effect of alumina’s physical properties on crusting and dissolution in molten bath was investigated in bench scale tests. These tests showed an improvement in crusting with increased loss-on-ignition (LOI) LOI is a laboratory procedure of measured weight loss from 300°–1000°C. levels. Th...

| 520 | |a Summary The effect of alumina’s physical properties on crusting and dissolution in molten bath was investigated in bench scale tests. These tests showed an improvement in crusting with increased loss-on-ignition (LOI) LOI is a laboratory procedure of measured weight loss from 300°–1000°C. levels. The improved crusting was largely attributed to the low levels of a alumina in the high LOI ore. An increase in the fines content to 30% −325 mesh did not affect crusting or dissolution. Above that level, crusting diminished and the dissolution rate increased. The dissolution rates of poor crusting aluminas are higher than those of aluminas which form a hard crust. This is due to the intimate contact between individual alumina particles and the bath. A 30-minute film, produced by Kaiser Aluminum, “Alumina Crusting and Dissolution,” presents the phenomena described in this report. | ||

Alumina Crusting and Dissolution in Molten Electrolyte |
| abstract |
Summary The effect of alumina’s physical properties on crusting and dissolution in molten bath was investigated in bench scale tests. These tests showed an improvement in crusting with increased loss-on-ignition (LOI) LOI is a laboratory procedure of measured weight loss from 300°–1000°C. levels. The improved crusting was largely attributed to the low levels of a alumina in the high LOI ore. An increase in the fines content to 30% −325 mesh did not affect crusting or dissolution. Above that level, crusting diminished and the dissolution rate increased. The dissolution rates of poor crusting aluminas are higher than those of aluminas which form a hard crust. This is due to the intimate contact between individual alumina particles and the bath. A 30-minute film, produced by Kaiser Aluminum, “Alumina Crusting and Dissolution,” presents the phenomena described in this report. © The Minerals, Metals & Materials Society 1982 |

The improved crusting was largely attributed to the low levels of a alumina in the high LOI ore. An increase in the fines content to 30% −325 mesh did not affect crusting or dissolution. Above that level, crusting diminished and the dissolution rate increased. The dissolution rates of poor crusting aluminas are higher than those of aluminas which form a hard crust. This is due to the intimate contact between individual alumina particles and the bath. A 30-minute film, produced by Kaiser Aluminum, “Alumina Crusting and Dissolution,” presents the phenomena described in this report. © The Minerals, Metals & Materials Society 1982 |

These tests showed an improvement in crusting with increased loss-on-ignition (LOI) LOI is a laboratory procedure of measured weight loss from 300°–1000°C. levels. The improved crusting was largely attributed to the low levels of a alumina in the high LOI ore. An increase in the fines content to 30% −325 mesh did not affect crusting or dissolution. Above that level, crusting diminished and the dissolution rate increased. The dissolution rates of poor crusting aluminas are higher than those of aluminas which form a hard crust. This is due to the intimate contact between individual alumina particles and the bath.
