The concentration of solids, post thickening, is performed by crystallisation in this process. Watercare Mining has a trademark registered Crystalactor pellet reactor. Crystalactor benefits include compactness, low maintenance as there are few moving parts, automatic sizing of the pellets produced and a low capital outlay. In many cases, its capital cost can be recovered through the sale of the minerals being recovered. The Crystalactor pellet reactor can be used in the following processes:
- Water softening (essentially cold-lime softening)
- Fluoride recovery
- Pre-treatment for ion-exchange processes
- Pre-treatment for brackish-water desalination
