ABSTRACT:
A process for forming agglomerates of metallurgical dust containing metal sulphates for recycling to extractive processes includes adding lime particles and a small amount of water, forming a mixture and extruding the damp mixture and allowing the extruded agglomerates to become hard and shape retentive. The material agglomerated may be water soluble metal sulphate containing particles or mixtures of such particles with other value metal bearing waste or by-products of metallurgical processes. Optionally additional binding agents comprising cement and hydrocarbonaceous substances such as wax may be added to the mixture.
