After recovery of the uranium, the barren solution is re-fortified with oxidant and complexing agent before being returned to the wellfield via the injection wells. However, a small flow (about 0.5%) is bled off to maintain a pressure gradient in the wellfield and this, with some solutions from surface processing, is treated as waste.

Sedimentation. Wollongong uses 2 different types of sedimentation processes. Traditional sedimentation allows solids to settle to the bottom of the tank while oil and grease float to the top. Scrapers at both the bottom and the top of the tanks remove the solids, oil and grease, which are treated to produce biosolids. A multi-flow tank (sometimes called a lamella plate) uses a set of stacked ...

Coal washing is accomplished by one of two major processes, by density separation or by froth flotation. Both processes depend on the fact that the particles of which a coal sample are made have different densities. When water, for example, is added to the sample, particles sink to various depths depending on their densities.

The mixture of pulverized coal and air is taken into the boiler and then burnt in the combustion zone. On ignition of the fuel, a large fireball is formed at the center of the boiler and a large amount of heat energy is radiated from it. The heat energy finds use to convert the water into steam at high temperature and pressure.

Metallurgical (met) coal (or coking coal) is a naturally occurring sedimentary rock found within the earth's crust. Categories of met coal include hard coking coal, semi-hard coking-coal, semi-soft coking coal and pulverised coal for injection (PCI). These apply to the different quality grades of met coal, all of which are used to make steel.

Coal facts. Coal is an organically derived material. It is formed from the remains of decayed plant material compacted into a solid through millions of years of chemical changes under pressure and heat. Its rich carbon content gives coal most of its energy content. When coal is burned in the presence of air or oxygen, heat energy is released.
