内容記述 |
Due to the long–term mining activity and economic growth of countries in the world, the depletion of high–grade copper ore has gradually been happening during the last several decades. With the decreasing of copper grade, the content of the copper ores becomes complex due to the increasing of impurities such as clay minerals and refractory ores. In addition, mine tailings are generally produced as a byproduct during the beneficiation of a copper ore, namely by flotation. The old mine tailings have higher copper grade than that of naturally occurring copper ore (world average: 0.4 %). Due to the lower grade and complex mineralization of copper ore and mine tailings, it becomes difficult to apply the conventional pyrometallurgical method to recover copper from that kind of resources. On the other hand, it can be expected that the demand for copper metal and copper–bearing products will be increased in the coming years. Hence, it becomes more important to address the processing of low–grade copper resources, especially low–grade copper ores and mine tailings by advanced flotation and hydrometallurgical method. In this research, the flotation and high–pressure oxidative leaching were developed for recovery of copper from the low–grade copper resources. This PhD thesis is composed of six (6) chapters, each of them dealing with different aspects of development the approaches for recovery of the copper from low–grade copper resources. |
