Method for separating e.g. calcite/quartz compounds during extracting mineral compounds of metal in deep mining application, involves crushing agglomerated particles, valuable materials and residue in density separation and floatation steps

摘要

The method involves agglomerating natural hydrophilic, completely or partially hydrophobic mineral grains by binding fluid by selective agglomeration according to a preceding sorting or classifying stage. Extracted agglomerates are separated from non-agglomerated hydrophilic particles in a film flow separation method. Agglomerated particles, valuable materials and residues are represented, enriched and crushed in density separation and floatation steps if a size the agglomerated particles, the materials and the residues exceeds a processing-specific grain size of a raw material. The binding fluid is oil. The processing-specific grain size is a flotation grain size boundary. An independent claim is also included for a device for separating agglomerated particles.
