The most common route for secondary lead recycling from battery scrap in the USA is the reverberatory smelting furnace. Detailed knowledge of operating conditions is important for selecting and developing the most suitable refractory materials for such a process route as they influence the refractory performance. This paper describes detailed mineralogical investigations on selected slag samples from a secondary lead smelter followed by laboratory test work (corrosion test with an induction furnace and a crucible test) with magnesia-chromite bricks. Based on the results of those tests refractory bricks with the highest corrosion resistance were selected for use in field trials. Investigations of post-mortem samples are carried out to understand the operational practice-orientated wear mechanism. This work was done to increase the refractory application knowledge of the lead smelting industry as well as providing customized refractory solution to RHI Magnesita’s customers.
