Other raw materials may be added, including iron, silica, limestone flux, coke, soda, ash, pyrite, zinc, caustic, and particulates gathered from pollution control devices. This trend is to “design for disassembly”. 2.2.1 Scrap Pretreatment Scrap pretreatment is the partial removal of metal and nonmetal contaminants from lead-bearing scrap and residue. BATTERY RECYCLING. The Short Rotary Furnace (SRF) is traditionally at the heart of the secondary lead (Pb) recycling plant to provide smelting of the products of spent automotive lead-acid batteries which have gone through a breaking and separation process. Lead Smelting Process: The Lead bearing material from Batteries, along with appropriate fluxes, reductants, Slag and other scrap & process wastes, is smelted in a Rotary Furnace depending on the product mix required e.g. Metalex Products Ltd. is a secondary lead smelting and refining facility located in Richmond, British Columbia, Canada. Lead Applications and Markets. Barakat Central Metallurgical R&D Institute (CMRDI), Industrial Wastes Laboratory, PO Box 87, Helwan, 11421 Cairo, Egypt Abstract This work discusses a method to suppress the fugitive emissions of total solid particles (TSP) and save energy for industrial lead smelters. Once lead is recovered from used materials, it is placed into a furnace where it is heated with coke or charcoal in order to isolate the lead from other compounds. Secondary manufacturers process recycled or scrap metals. secondary lead smelter means any plant or factory in which lead-bearing scrap or lead-bearing materials, other than lead-bearing concentrates derived from a mining operation, are processed by metallurgical or chemical process into refined lead, lead alloys or lead oxide; (fonderie de plomb de seconde fusion) undiluted Lead Smelting. Smelting & Refining Process for production of Pure Lead out of Lead bearing material. Secondary Lead Smelting Objectives • Describe the basic smelting process terms: smelting, refining, and alloying • List key chemicals associated with secondary lead smelting • Define volatility temperature, volatile metals, and metals partitioning. It has relatively low capital and operating costs for a smelting process. 1989 : HOLLANDSE METALLURGISCHE INDUSTRIE BILLITON B.V., The Netherlands Study of the application … Proper Treatment of Effluent generated while Pollution Control Crushing & Separation of Lead Bearing material & other component of Battery. Of the more than 60 known lead-containing minerals, by far the most important primary ore of the metal is the lead sulfide galena (PbS). Extraction processes include chemical addition (e.g. 5).These materials may be charged directly into smelting furnaces or mixed with other charge materials. Secondary lead production involves the collection and purification of lead bearing scrap material for reuse. Design of production and pollution control equipment and supply of process technology for upgrading primary and secondary lead smelter from 8,000 to 20,000 TPY. A process for producing metallic lead from lead battery plates and other types of lead scrap in a secondary lead smelting operation has been developed which comprises adding from 1% to 8% moisture and 0.5% to 5% oxygen to the air which is used to react with carbonaceous material such as coke to maintain the temperature in the melting region from about 1100° C. to about 1300° C. The Secondary Smelting Process Secondary smelting of lead is similar to primary smelting, but does not require the initial sintering process. Managing complex material streams within a lead smelting/reduction process has a long history at Aurubis. LEAD SMELTING. smelting process that is easy to operate. Depending on added flux during the battery paste smelting, various types of slag can be obtained: silica slag, calcium slag and sodium slag (produced by adding Na2CO3 as flux).
