Equipment for removing clay from bauxite
December.23,2024
At present, for easy-to-wash bauxite, a two-stage washing process of drum ore washer (also called drum ore washer) and trough ore washer is used. For difficult-to-wash ores, a three-stage washing process of drum ore washer, trough ore washer and linear vibrating screen is used. Washing is the simplest and most effective way to increase the aluminum-silicon ratio of bauxite. Generally, washing can double the aluminum-silicon ratio of bauxite, which is more effective for sorting loose ores. Washing is usually combined with other sorting methods to improve recovery efficiency.
The mud or clay in bauxite has a significant impact on the washability of ore sand. Because the particles of clay are very fine, water is firmly retained between them. Therefore, clay is actually a two-phase system consisting of a solid phase and a liquid phase (water). Whether the clay-containing ore sand is easy to disperse after the crushing operation is related to the plasticity and expansion of the clay itself.
