Slag granulation

The processes used in the primary production of lead produce several wastestreams of concern under different regulatory scenarios. The listed RCRA hazardous wastes include smelting plant wastes that are sent to surface impoundments to settle. The impoundments are used to collect solids from miscellaneous slurries, such as acid plant blowdown, slag granulation water, and plant...

Multiple use of treated waste water Multiple use of treated waste water needs to be considered, e.g. using process water from sand preparation in the moulding sand cycle or in slag granulation. The use of cooling water in wet scrubbing may also be considered Use of waste heat for the evaporation of waste water This technique can only be applied when waste heat is available on a continuous basis. A case-by-case evaluation is needed to evaluate its applicability and economic viability... 

The filtrate is passed via a turbidity meter into a storage tank in which pH and conductivity are monitored. There are three possibilities for where it goes from there via an equalising tank to slag granulation or dry dust humidification back to the sludge silo (if the turbidity limit is exceeded) to drain (emergency measure only).

During the initial period of KIVCET operation, the most significant mechanical problems were external to the KIVCET fiomace itself These were related to the feed system, slag and bullion launders, and the slag granulation system.
