Lead RefiningPlant Mettherm provideslead refining equipmentfor providingleadas per the international purity standard of secondaryleadi.e. 99.97% and above. The Process: Theleadreceived from Rotary Furnace is called hardlead/crudelead.Theleadtapped from the furnace has to be cleaned from residual oxides and slag.[email protected]
Therefining unitcomplement is completed by the automatic Lead ingot-casting machine (withLead-Pump) having a production capacity of up to 10-20 MT/hr.Refining unit packageis optimally configured for high throughput with good emission control, as proven by the existing installations in operation.
There are 28refining-tanks, each 86 in. long, 30 in. wide and 42 in. deep, and each receiving 22 anodes oflead-bullionwith an area of 26 by 33 in. exposed to the electrolyte on each side, and 23 cathodes ofsheet-lead, about 1/16 in. thick, prepared by deposition onlead-platedand paraffined-iron cathodes.
The pyrometallurgicalLead refiningprocess is one of the most important procedures ofleadbatteryrecycling. This process is also known as “Softening ofLead”because the metal is softened after the removal of some impurities which are present in the rawleadcoming fromleadbatteryrecycling. It would be more correct to call only the process of antimony, arsenic and tin removing “softening”.
The Lead refining furnace consists of aRefining Kettle/Pot, Shell, Refractory Lining,Exhaust duct, Agitator, Hood & Burner etc. The hood is normally provided with each refining kettle to absorb all the acidic fumes generated during the refining operations and convey it to the filtration system (Bag house, ID Fan & Stack duct and Wet scrubber).
Removal ofleadfrom protectiveclothingorequipmentby blowing, shaking, or any other means which dispersesleadinto the air is prohibited. [ 29 CFR 1910.1025(g)(2)(viii) ] (Fig. 2) . Raw Materials Processing | Smelting |Refiningand Casting | Environmental Controls

Primary lead production begins with sintering. Concentrated lead ore is fed into a sintering machine with iron, silica, limestone fluxes, coke, soda ash, pyrite, zinc, caustics or pollution control particulates. Smelting uses suitable reducing substances that will combine …
Lead Refining The process of removing unwanted contaminants by various treatments carried out on a bath of molten Lead is known as Lead refining. Primary Lead production is usually viewed in terms of two distinct operations converting Lead concentrate to bullion and refining the bullion.

Leadprocessing -Lead processing - The metal and itsalloys: Refinedleadusually has a purity of 99 to 99.99 percent, butleadof 99.999 percent purity (known as “five nines”) is becoming more common commercially. At these levels, the grades ofleaddiffer mostly by their bismuth content. With modern smelting andrefiningtechniques, it is possible to reach these high levels of purity ...
Leadfor recycling may be in the form of scrap metal (roofing sheet, for example), or compounds oflead, such as the pastes fromlead-acid batteries. Clean metallicleadcan be melted and refined directly, but compounds andleadalloys require smelting, using processes similar to those used withleadores.
Therefiningunit complement is completed by the automaticLead- Ingot Casting machine (withLeadpump) having the capacity of upto 25 tons/ hour. Ourrefiningunit package is optimally configured for high output with excellent emission control. The impurities present in crudeLead…
Fire-refiningcan produce fineleadof different grade andleadalloys by using several kettles, requiring simpleequipment, less investment and land space.Leadbullion containing less bismuth and precious metal is suitable to fire-refining.
The most important aspect ofLeadSmelting operation is treatment of effluent gases, which generates by reduction / smelting operation.Pollution control equipment’s are designed and tested in house at various degree of operations on various atmospheric conditions.
Lead SmeltingPlant /Lead SmeltingEquipments Smelting Section : TheLeadbearing material from Batteries, along with appropriate fluxes, reductants, Slag and other scrap & process wastes, is smelted in a Blast/ Rotary Furnace or a combination of the two, depending on the product mix required e.g. hard AntimonialLead, soft crudeLeadetc.
Leadprocessing -Lead processing - Mining and concentrating: Once the ore is removed from veins (narrow channels) or lodes (roughly spherical deposits) in the Earth, usually at depths of about 60 metres, the ore is treated at concentrating mills. Here the ore is finely crushed, sometimes to particle diameters of less than 0.1 millimetre (0.004 inch), and then treated by one of several mineral ...
An overview on how to refine precious metals. There are many kinds of materials that yield pure gold, platinum, or silver when refined. Though it's usually a little intimidating the first time you do anything,refiningprecious metals yourself is relatively easy to do (even with no experience) provided you have the right information, supplies, andequipment.
Plants for the production ofleadare generally referred to asleadsmelters.Primaryleadproduction begins with sintering.Concentratedleadore is fed into a sintering machine with iron, silica, limestone fluxes, coke, soda ash, pyrite, zinc, caustics or pollution control particulates. Smelting uses suitable reducing substances that will combine with those oxidizing elements to free the metal.
Leadrecycled from usedleadacid batteries or other sources (Secondary Smelting) via the Mini Blast Furnace or RotaryFurnace route, contains lot of contamination and undesired components. On the other hand,Leadrequired for batterymanufacturing is either softLeadwith 99.97% purity or hardLeadof varying Antimony compositions.
