Tailings produced from the milling of sulfide ores — primarily copper, lead, and zinc ores — may have concentrations of pyrite that are greater than those common in waste rock. Also, because tailings are composed of small mineral particles the size of fine sand and smaller, they can react with air and water more readily than waste rocks.

The presence of zinc and lead ions in the ISF slag are proven to have an impact on the setting characteristics of concrete mixtures, although there is little difference in the compressive strengths after 28 days. The leaching, characteristics of the slag suggest that the retardation is not linearly related to the quantities of zinc or lead leached.

Lead recycling is almost ubiquitous for vehicle batteries, but other types of lead-acid batteries such as sealed lead acid batteries and valve-regulated lead acid batteries can also be recycled. EHLS currently manages lead-acid batteries as scrap metal due to their high value.

2. Does EPA support beneficial uses of silica-based spent foundry sand? Based on the conclusions of the risk assessment and the available environmental and economic benefits, the EPA supports the beneficial use of silica-based spent foundry sands specifically from iron, steel and aluminum foundries, when used in manufactured soils, soil-less potting media, and roadway construction as subbase.
