Fly ash - Wikipedia

Fly ash or flue ash, also known as pulverised fuel ash in the United Kingdom, is a coal combustion product that is composed of the particulates (fine particles of burned fuel) that are driven out of coal-fired boilers together with the flue gases. Ash that falls to the bottom of the boiler is called bottom ash.MP618™ Multi-Process Fly Ash Beneficiation Technology,,Increase Your Fly Ash Sales And Supply. Our proprietary MP618™ Multi-Process fly ash thermal beneficiation technology improves the quality of fly ash produced by electric utilities and increases the supply of marketable fly ash to concrete producers nationwide. MP618 reduces loss on ignition (LOI), ammonia, activated carbon and moisture in fly ash.Recycling transforms fly ash into 'eco-minerals',,RockTron’s fly ash beneficiation process uses a traditional mining technology, called 'froth flotation' (Fig. 2). This separates and washes the components that make up fly ash to produce new eco-minerals which have many applications.
