METHOD FOR PRODUCING A BULK CONCENTRATE

摘要

The invention relates to methods for producing a bulk enrichment concentrate for extracting noble metals from clay-salt waste (slurries) from plants which process potassium-magnesium ores and rock salt.  The method for producing a bulk concentrate for extracting noble metals involves the three-stage hydrocyclone separation of the slurries and the isolation of the concentrate. The bulk concentrate produced by the hydrocyclone separation in the form of a mixture of sedimentary and floating material with a 1:1 solid-to-liquid ratio is desiccated, pre-dried, granulated and then dried.
