A process for the intensification of the dry separation of natural minerals and synthetically produced products with mineral character or intensification of the separation of flue polyethylene phase

摘要

Separation of solids from liquids or solids from solids is facilitated by applying a wide range of anionic or non-ionic surface active agents. Separation may involve filtering or settling of a suspension or wet or dry screening to classify solid particles. The agents are added in specific amounts to the suspension or dissolved in water and applied to the solids before screening. Solids may be coal, barium sulphate, calcium carbonate, quartz or ashes.
