1. Design and Development of Mineral Structure Specific Collectors in Flotation
Sammanfattning : The success of mineral flotation processes depends on the hydrophobization of the surface for the desired mineral particles whilst keeping, or making, all other minerals hydrophilic. This is achieved by adding several reagents to the flotation pulp to adsorb selectively at the mineral/water interface. LÄS MER
2. Selectivity in Calcium mineral flotation - An analysis of novel an existing approaches
Sammanfattning : .... LÄS MER
3. Application of Chemical Additives in Minerals Beneficiation – Implications on Grinding and Flotation Performance
Sammanfattning : The application of chemical additives, known as grinding aids (GAs), dates to 1930 in the cement industry. Unlike the cement industry, where the use of GAs is in the final processing step, it could be one of the first processing steps in ore beneficiation. LÄS MER
4. Comparative Study of Chemical Additives Effects on Dry Grinding Performance
Sammanfattning : The application of chemical additives, known as grinding aids (GA), dates back to 1930 in the cement industry. As opposed to the cement industry, where the use of GAs is on the final processing step, it could be one of the first process steps in ore beneficiation. LÄS MER
5. 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
