  • Power Station Slag Recycling - Case Study

    The problem: Coal fired power stations operating tap slag boilers release most of the ashes resulting from the combustion as slag at the boiler bottom. There is a number of such power stations in Europe operative. These boilers are also known as wet bottom boilers. There are two types of wet-bottom boilers: the slag-tap boiler and the cyclone boiler. The slag-tap boiler burns ...

  • A novel approach to remediating contaminated groundwater by reusing industrial co-products

    This paper presents a novel approach to remediating contaminated groundwater by utilising industrial co-products. The materials discussed include paper clay and steel slag, and the primary water contamination considered is heavy metal contamination. Paper clay was determined to have the potential for adsorbing heavy metals, and in compacted form could achieve permeability values within the ...

  • Recovery of aluminium alloys and some valuable salts from Spent Bottle Covers

    This work provides a method to prepare standard Al-alloy(s) and some salts of market value from Spent Bottle Covers (SBCs). Aluminium covers were separated from others made of iron or plastic by magnetic and flotation techniques. The aluminium covers were melted under flux. Metals went into the slag were leached using hydrochloric acid. Results obtained revealed that the removed paint decomposed ...

  • 25 Years of Success – Outokumpu Stainless DC Plasma Smelting Facility

    Design is not just what is looks and feels like. Design is how it works. Between 1982 and 1987, British Steel (Outokumpu today) made extensive investigations into the treatment of steel dust. Their research was far and wide and covered off many various methods of recycling, including alternative to plasma technologies. But, in 1985, they engaged Tetronics International to carry out a ...
