摘要：<p>A process for producing brick involves calcining electric arc furnace dust and subsequently mixing the dust with a brick raw material prior to shaping the material into bricks and firing. The precalcination of the EAF dust greatly increases the bulk density of the dust and provides a brick having a much higher compressive strength when compared to bricks incorporating raw dust which has not been precalcined. Volatilized and recondensed heavy metals produced during the calcination process are collected and refined. As a result of the separation and collection of the volatilized heavy metals during the calcination process, substantially no heavy metals are volatilized during the brick firing process.</p>
