The present invention is one combined pyrometallurgical and wet metallurgical process. The smelting of regenerated lead in crucible furnace has low smelting temperature, and less loss of Pb, Sb and other elements, the lead-antimony alloy may be used in manufacturing slab lattice and connecting part of accumulator, lead nitrate produced with waste accumulator may be used in the production of Author: 过康民. A thermodynamic analysis of the rotary furnace process for the recovery of lead from battery residue by carbothermic reduction with soda ash (Na 2 CO 3) was le models were selected to represent the thermodynamic behaviour of the bullion, matte, slag and gas by: 8.

New sulfur dioxide-free process for recovering lead from battery scrap. [Washington]: U.S. Dept. of the Interior, Bureau of Mines,  (OCoLC) Online version: Wilson, Donald A. New sulfur dioxide-free process for recovering lead from battery scrap. [Washington]: U.S.
Dept. of the Interior, Bureau of Mines,  (OCoLC) A laboratory method for processing lead battery scrap has been developed that eliminates virtually all of the so2 emission that normally is produced when a reverberatory or blast furnace is used.
The method employs a hydrometallurgical step to convert the pbso4 to pbo and caso4 by mixing the battery scrap with a slurry of ca(oh)2. A new sulfur dioxide-free process for recovering lead from battery scrap / By Donald A. Wilson and United States. Bureau of Mines.
Abstract. Item es bibliographical references (p. ).Mode of access: Internet. Thus, the process will recover and trap % of the contained sulfur in the battery or virtually all the sulfur in the battery.
Figure 1 depicts the flow sheet as a block diagram which shows the various steps. In the process, spent batteries are crushed (1) and the acid (2) is recovered for later use. An innovative lead recycling process from scrap lead-acid battery paste is presented.
The novelty in the process is avoiding SO 2 generation and emission by using reductive sulfur-fixing technique.
Iron-bearing secondary wastes produced from metallurgical industry were utilized as sulfur-fixing agent to capture sulfur in the form of FeS (s) instead of generation of SO 2 (g).Cited by: 1. Process parameters of sulfur removal from the active mass of lead battery scrap, the main type of lead-containing secondary raw materials, were discussed.

The energy consumption per ton lead is as low as kWh at 20 mA cm − 2. The recovery rate of Pb can reach up to % in the electrolytic by: A novel and cleaner process for lead and silver recycling from multiple lead-containing wastes, e.g., lead ash, lead sludge, lead slag, and ferric sludge, by reductive sulfur-fixing smelting was.
Of the two methods of sulfur capture in lead–acid battery recycling, the pyrometallurgical method is more common. In this process, sulfur-capture is accomplished in a two-stage process. Sulfur dioxide is first produced via a carbothermic reduction of PbSO 4 and the subsequent sulfur-capture is accomplished by scrubbing SO by: 6.
I use a Lee Production electric pot to refine lead recovered from several sources to recover the alloy for making bullets. A new process of lead recovery from waste lead-acid batteries by electrolysis of alkaline lead oxide solution Article in Electrochemistry Communications 19(1)–72 June with Reads.
A new basic electrolytic method for recovering lead from scrap batteries was proposed, with NaOH as sulphur-eliminating agent and self-made I# as reducing-converting agent.
This study developed a vacuum chlorinating process for simultaneous sulfur fixation and high-purity lead chloride (PbCl2) recovery from spent lead paste by using calcium chloride (CaCl2) and.

RECYCLING OF LEAD. RECYCLING PROCESSES. The main stages of the recycling process are: Collection and transportation - via one of several routes to scrap dealers, or in the case of batteries, to battery wholesalers, then to producers of secondary Size: 52KB.
Process parameters of sulfur removal from the active mass of lead battery scrap, the main type of lead-containing secondary raw materials, were discussed. Process parameters of sulfur removal from the active mass of lead battery scrap, the main type of lead-containing secondary raw materials, were discussed.
vol. 31, book 3, pp. Cited by: 8. Lead in the global market is traded as soft lead, animated lead, lead alloys and copper-base scrap. Pure Lead Refining Process, producing Pure Lead Ingots with a minimum purity level of % by weight but achieves purity level of % in most of cases.
SCRAP DRAINED/DRY WHOLE INTACT LEAD BATTERIES: To be free of any liquid. Cases to be either plastic or rubber and be complete including caps. Non-lead (ni-cad, ni-fe, carbonaire, etc.) not acceptable. Industrial steel cased, aircraft (aluminium cased) and partial, cracked or broken batteries and batteries without caps subject to special agreement.

There is a limited scope for import of lead battery scrap due to Basel Convention for trans-boundary movement of Hazardous Scrap. Now in days the limited availability of lead concentrate is a major reduce factor both for capacity expansion in existing smelters and for establishing new primary smelters.
information by directing them to the best available A new sulfur dioxide-free process for recovering lead from battery scrap, Donald A. Wilson, United States. Bureau of Mines,Electric batteries, 13 pages The speed at which Sidney Nolan worked, and the expansiveness of his.Lead-Acid Batteries Collection and recycling of Pb-acid batteries is a well established process that allows recovering of automotive and industrial batteries at very high rates.
The small sealed batteries described in Chapter 5 are added to the stream of the large ones and treated in the same way. Making a batch of lead metal ingots, and cooking concentrated sulfuric acid we got from the battery of my car! Hooray for backyard science.
