11. Bringing predictability into a geometallurgical program : An iron ore case study
Sammanfattning : The risks of starting, operating and closing mining projects have become higher than ever. In order to stay ahead of the competition, mining companies have to manage various risks: technical, environmental, legal, regulatory, political, cyber, financial and social. Some of these can be mitigated with the help of geometallurgy. LÄS MER
12. Geometallurgical programs – critical evaluation of applied methods and techniques
Sammanfattning : Geometallurgy is a team-based multidisciplinary approach aimed at integrating geological, mineralogical and metallurgical information and yielding a spatial quantitative predictive model for production management. Production management includes forecast, control and optimization of the product quality (concentrates and tailings) and metallurgical performance (e. LÄS MER
13. Sampling from large flotation cells : An invastigation of spatial distribution
Sammanfattning : The general trend in flotation technology today is towards larger flotation cells, which enables a higher throughput. However, adverse effects such as segregation and reduced froth transport efficiency have also been observed in larger cells. LÄS MER
14. Geometallurgical study of historical tailings from the Yxsjöberg tungsten mine in Sweden : Characterization and reprocessing options
Sammanfattning : Tungsten (W) is listed among the European Union (EU) critical raw materials (CRMs) for its supply risk and economic importance. Primarily, tungsten is produced from scheelite and wolframite mineral ores with 0.08-1.5% tungsten trioxide (WO3) grade. LÄS MER
15. Reprocessing historical tailings for possible remediation and recovery of critical metals and minerals : The Yxsjöberg case
Sammanfattning : With increasing consumption of primary mineral resources, the generation of mining wastes has also increased thus requiring the mining industry to address the growing environmental concerns. Waste rock and tailings are potential secondary sources of critical raw materials currently in short supply in the European Union, but also a source for environmental issues like acid mine drainage.
