Abstract
Molten blast furnace slag is quenched by a volume of water divided into two streams. The first stream is directed downwardly against the slag while the second stream is directed horizontally against the slag. The molten slag is broken down into relatively fine sand-like granules which are kept submerged in the water. The vapors formed during granulation are substantially free of detectable SO.sub.2 and the H.sub.2 S formed and vented to the atmosphere is insufficient to be a detriment to the surrounding environment.
