Red Mud Sample
The study focuses on the composition, structure, and properties of stagnant gold mining tailings to determine the efficiency of their enrichment in a vortex air-mineral flow. Conducted in a specialized laboratory facility for testing technogenic mineral raw materials, this work employs the innovative eco-technology of dry complex enrichment (DEC).
To initiate the study, provide one representative sample weighing up to 40 kg, specifying the selection location on the site plan. It's essential to note that conclusions drawn from the tested enrichment of the provided sample are specific to the material and may not apply universally to the entire dump or other types of stale tailings.
