Methods for Beneficiation of Ash and Slag Waste from

2019-4-17  Abstract— Ash and slag waste (ASW) from coal-fired thermal power plants (TPPs), the amounts of which make several tens or even hundreds of millions of tons per annum, require allocation of large land areas for storing them. This waste is a source of pollution emitted into the atmosphere and it poisons the aqueous medium and soil. Ash and slag waste consists primarily of powderlike material ...

Power Station Slag Recycling - Dirk Group

The solution: The molten and then crystallized slag is washed out of the power station into a slag pond. The wet ash is extracted from the pond and left in the open to loose most of the quenching water. Thereafter the slag is dried in a rotating dryer to dry and de-agglomerate bigger particles before screening in to five different particle sizes.
