Drossing produces two different materials: dross and molten lead. Dross is a material that consists of antimony, copper, lead oxides and possibly other elements in the concoction. Professionals obtain the dross because it moves toward the top of the lead mixture.

The refining of crude lead takes place in a refining kettle at temperatures between 400 and 550°C. If only battery scrap is used for lead production, two subsequent refining steps are required: 1. Removal of Cu which might have entered the melts through copper wires. 2. Removal of antimony originated from the former grid metal to produce pure lead

The scope is the removal of many of the foreign metals and of impurities in order to produce either soft lead and all the alloys required by the market. All the ancillary equipment like pumps, agitators, dross removers, oxy injectors etc are used for such operations.
Lead: Secondary Lead Smelter eTool Refining and Casting
Lead fumes may be emitted while heating the lead reservoir and casting equipment. Emissions may occur during the pouring and cooling of lead castings. Lead fumes and dust may be emitted during the drossing of lead oxides from the reservoir and casting surfaces (Fig. 2).
Rotary Furnace for Lead Battery Recycling Gravita India Ltd
Rotary furnace is design for treatment and recovery of Lead from Lead Acid Batteries Scrap and for the reduction of Lead Sulphate, Lead Oxides, Lead Concentrates, Lead Dross and Lead Ore. Rotary Furnace will work at temperature of about 10001200 C.
Preparation of Calcium Stannate from Lead Refining Dross
Lead refining dross containing plenty of tin and other heavy metals, such as lead and antimony, is considered a hazardous waste generated in large quantities in lead smelter plants. In this study, calcium stannate was synthesized from lead refining dross using sodium carbonate roasting and alkaline leaching followed by precipitation with CaO.
In metallurgy, refining consists of purifying an impure metal. It is to be distinguished from other processes such as smelting and calcining in that those two involve a chemical change to the raw material, whereas in refining, the final material is usually identical chemically to the original one, only it is purer.
Leadrefining Dross Refining dross is the result of lead refining process where impurities like copper, tellurium, arsenicantimonytin, silver, zinc and bismuth in sequence from lead bullion. There are many types and composition of each type of dross varies and is subjected to specific refining steps and raw material contents.
Copper, Lead and Zinc Smelting and Refining along with copper, antimony and other elements, floats to the top and solidifies above the molten lead. The dross is removed and fed into a dross furnace for recovery of the nonlead useful metals. To enhance copper recovery, drossed lead bullion is treated by adding sulphurbearing materials

Refining of lead from lead battery recycling STC Italy
Refining of lead from lead battery recycling The pyrometallurgical Lead refining process is one of the most important procedures of lead battery recycling. This process is also known as "Softening of Lead" because the metal is softened after the removal of some impurities which are present in the raw lead coming from lead battery recycling.
Pb Sb Sn Dross From Pb Refining Process Recovery Vacuum
Lead and Zinc Smelting International Finance Corporation. is fed into a dross furnace for recovery of the nonlead mineral values. The lead bullion is refined using pyrometal lurgical methods to remove any remaining nonlead materials (e.g., gold, silver, bismuth, zinc, and metal oxides such as oxides of antimony, arsenic, tin, and copper).
Nov 06, 2018 · The more stirring and splashing you make will make more lead dross due to exposure to oxygen. I spend a lot of my working life in a lead refinery surrounded by five or six 235 ton pots and a couple of small pots full of molten lead. The refinery produce 99.999% pure lead through the Betts electrolytic refining process.
