Blast furnace has been used for lead ore/concentrate smelting for a long time.It plays a fundamental role to modern metallurgy and is still very important in the small-scale smelting application.
Features: High heat efficiency: furnace burden heated by the waste heat of the off-gas. High recovery rate: The molten lead and slag will be separated completely in blast furnace hearth, because the blast furnace hearth has higher temperature and more obvious slag line than rotary furnace to sedimentate the lead metal from slag.
We have designed and developed a special blast furnace, the GBF (patent pending), for Secondary Lead Smelting which combines the features of low set-up and operating costs, high process efficiency, low maintenance requirements due to no moving parts and user-friendly features. This furnace can achieve production levels of up to 12 tonnes/day.
9. Fugitive emissions from the blast furnace, including leaks from the furnace covers and the bottoms of charge cars, dust from the charge car bottom dump during normal operation, and escaping gases when blow holes develop in the shaft and must be "shot" with explosives; 10. Lead fumes from the molten lead and slag leaving the blast furnace .
The Process of SmeltingKey Pieces of Equipment in SmeltingThe Parkes ProcessHistory of Lead SmeltingLead Production in The United StatesOther Processes Necessary to Create LeadNumber of Lead Smelting Plants Left12.11.2.2 Smelting - Smelting produces lead by melting and separating the lead from metal and nonmetallic contaminants and by reducing oxides to elemental lead. Smelting is carried out in blast, reverberatory, and rotary kiln furnaces. Blast furnaces produce hard or antimonial lead containing about 10 percent antimony.
The blast furnace is adaptable to both lead concentrate/ lead paste and their mixture. This advantage allows smelters to adjust the production plan as per the market fluctuation of recycling industry. The off-gas treatment to the lead paste smelting enhances lead recovery and improves environmental index.

· Key Pieces of Equipment in Smelting. A crucial component in creating lead is the blast furnace. The furnace is a giant steel stack that typically gets lined with refractory bricks. Its purpose is to create liquid iron from chemically transforming iron oxides. Limestone, coke and iron ore are also thrown into the blast furnace.
12.11.2.2 Smelting - Smelting produces lead by melting and separating the lead from metal and nonmetallic contaminants and by reducing oxides to elemental lead. Smelting is carried out in blast, reverberatory, and rotary kiln furnaces. Blast furnaces produce hard or antimonial lead containing about 10 percent antimony.
blast furnace slag (primarily silicates), and lead bullion (98% by weight). All layers are then drained off. The speiss and matte are sold to cop-per smelters for recovery of copper and precious metals. The blast furnace slag, which contains zinc, iron, silica, and lime, is stored in piles and is partially recycled. Sulfur oxide emissions are
4.1 Smelting of Lead. The conventional process for smelting lead involves roasting a mixture of lead sulfide concentrate and flux on a sinter machine, followed by blast furnace smelting. Environmental and energy considerations have prompted studies of a more direct route, a so-called “direct” smelting …
The zinc-lead blast furnace. Sintered zinc and lead concentrates, mixed with metallurgical coke, are charged into the top of a shaft furnace, into which preheated air is blown through nozzles, or tuyeres, at the base (see figure).This procedure is similar to that followed in an iron blast furnace, with the important difference that the major products of reduction here are a zinc-bearing gas .
At present, primary lead production in China is performed via traditional sintering blast furnace smelting, the Shuikoushan process, the Isa smelt system, the Kaldo converter lead smelting process .
The blast furnace reduces the oxidized lead slag from the smelter together with high lead containing third party raw materials and transforms them into impure lead bullion, nickel speiss, copper matte and depleted slag. The impure lead bullion, collecting most of the non-precious metals, is further treated in the lead refinery.
· A blast furnace is a block that smelts ores, metal armor and tools, similar to a furnace, but at twice the rate. It also serves as an armorer's job site block. 1 Obtaining 1.1 Breaking 1.2 Natural generation 1.3 Crafting 2 Usage 2.1 Smelting 2.2 Light source 2.3 Custom name 2.4 Change profession 2.5 Lock 2.6 Note Blocks 3 Sounds 3.1 Generic 3.2 Unique 4 Data values 4.1 ID 4.2 Metadata 4.3 .
Smelting Section: The Lead bearing 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 Antimonial Lead, soft crude Lead etc. The furnaces operate in a temperature range of 900 .
smelting furnaces or pot furnaces. 2.2.2 Smelting Smelting produces lead by melting and separating the lead from metal and nonmetallic contaminants and by reducing oxides to elemental lead. Smelting is carried out in blast (SCC# 3-04-004-03), reverberatory (SCC# 3-04-004-02), and rotary kiln (SCC# 3-04-004-99) furnaces.
Blast Furnace For Small Scale Lead Recycling Unit. These blast furnace are also called coke fired furnaces and are available in forms of: 1. Single Mini Blast furnace for production of Lead ingot upto 50 MT per month. 1a. This furnace comes with two ovens (only one operational at a time)
The process for operating the Blast Furnace is as follows: Place coal and/or ore on the Conveyor Belt. Cool down smelted bars with a bucket of water or just collect the bars with the ice gloves equipped. Collect the bars from the bar dispenser. Repeat.
