How to dewater tailings slurries with slimes and ultra-fines
I have consulted with several mineral processing experts on their experience and definitions. From these conversations, my understanding is that a slurry with a d 50 of <10µm micron, and with a P 80 of 45µm, would be considered a slimes stream. It often contains ultra-fine particles of the parent rock (e.g. quartz) and silts.Web

Phosphatic waste clay: Origin, composition, physicochemical properties
This can be accomplished using hydro-cyclones with a 50.8-cm (20 in.) diameter. The fraction finer than 0.1 mm, known as waste clay or phosphate slime, is pumped as a slurry of 3% solids into a clay settling pond (Zhang et al., 2017, Zhang and Bogan, 1995). This slime accounts for at least one-third of the mined ore.Web
