Tin Processing | Equipment, Process Flow, Cases
Desliming is the key part of the tin gravity separation process, which directly affects the separating effect. In China, more than 80% of the raw tin ore is placer tin deposit. The desliming process is actually divided into two stages, one is dissociation and dispersion of the slime, and the other is the separation of mud and sand.
