Abstract

Chemical and particle-size composition of slimes from accumulator factory has been investigated. It has been demonstrated that basic part of lead therein is presented by carbonate and oxidic compounds, and in view of fine dispersity of the products, conventional methods of producing lead from slimes are unsuitable. Laboratory tests of two variations of a cementation procedure to reclaim lead from sewage slimes of accumulator factory have been performed. They included the one with intermediate obtaining pure lead sulphate and with direct cementation of lead from a sulphate product. It has been demonstrated that both of variations provide practically complete regeneration of lead to yield marketable products. Advantages and limitations of both variations have been discussed.
