| Abstract Scope |
A general problem with separation processes, such as flotation and chemical separation, is they typically need fine particles to get a proper separation of the different materials (e.g., ore and waste). However, coarser particles are required for a further sintering process or the application in refractories. Therefore, the fine (sometimes extreme fine) particles must be agglomerated to generate larger grains. The main processes for this purpose are briquetting, granulation, or a melting process.
Briquetting is performed with a high amount of mechanical energy to compact the fine particles using a briquetting press.
For a granulation process (large) drums or pelletizers are used. The process starts with a seed granule to which the fine powder agglomerates and normally this process runs with water and/or binders.
The last process to mention is the smelting (or fusion) process, where the material is heated up until it melts and subsequently agglomerates during cooling. |
