investigation of landfill disposal of blast furnace slag from secondary lead smelters by Nancy Karen Fish Woodley Download PDF EPUB FB2

Blast furnace tapping operations involve removing the slag and then tapping molten lead from the furnace into molds or ladles. Some smelters tap metal directly investigation of landfill disposal of blast furnace slag from secondary lead smelters book a holding kettle which keeps the metal molten for refining.

The other smelters cast the furnace metal into blocks and allow the blocks to solidify. Potential Sources of Exposure: Lead fumes may be emitted at the lead or slag tapping plugs. Pollution control is no longer a cost of doing business, but is a prerequisite. Today, secondary lead smelters are perceived as specialists in the field of waste management, offering as a service to lead-using industries the proper handling of lead-bearing wastes through recycling.

Lead dust may become airborne due to the disturbance of settled dust in the smelting area. Ladles containing slag or molten lead may emit fumes. Spilled slag or molten lead may emit lead fumes. Possible Engineering and Work Practice Controls: Provide local exhaust ventilation at the lead and slag tap, launders, molds, ladles, and refining.

The blast fur- naces are tapped continuously to remove lead and intermittently to remove the slag. The blast slag, which contains primarily silica and iron oxides, is transported to an offsite landfill for disposal.

Lead produced in the blast and rever- beratory furnaces is transferred to the re- fining process where additional metals are added to make specific lead alloys. Slag-disposal ratio The slag-disposal ratio (SR) is the amount of blast slag produced by the test furnace divided by the amount of slag produced by the control furnace.

This is another term that is exclusive to the blast furnaces because reverberatory slag is fed to the blast furnace, while the blast slag is by: Twelve suspected former secondary lead smelting sites were investigated. Ten of the sites were confirmed to be former secondary lead smelters or lead works by investigation of landfill disposal of blast furnace slag from secondary lead smelters book fire insurance maps and.

Factors in selecting reclamation using secondary lead smelters for the materials found at Superfund sites include: Lead concentration; Material type (dross, debris, slag, soil, etc.); Density of the material; Sulfur, calcium, iron, antimony, soil, aluminum, and silica concentrations; Moisture content (smelters generally cannot accept wet materials); Presence of organic wastes, haiogenated materials, and gaseous materials.

Blast furnace slag is a by-product from blast furnaces which is used to investigation of landfill disposal of blast furnace slag from secondary lead smelters book iron. Blast furnace slag has been used extensively as a successful replacement material for Portland cement in concrete materials to improve durability, produce high strength and high performance concrete, and brings environmental and economic benefits together, such as resource conservation and energy by: Sodium lead slag, generated during secondary lead production, is characterized as hazardous waste.

The aim of the study was to investigate leaching mechanism and behaviour of lead and arsenic from sodium lead slag previously stabilized/solidified in concrete using additives: MgO, CaO, Ba(OH)2 and gypsum.

characterization provides useful information in case of the dusts recycling, finding the source in case of an accidental pollution, as well as on the blast furnace efficiency.

Keywords: blast furnace, wastes, optical microscopy, dust bag, dust cyclone, sludge 1. Introduction During the production of iron about 2 tons of waste are generated per ton. Even though it can be recycled, slag is frequently sent to landfills for disposal.

In producing steel, iron ore is introduced into a blast furnace. Slag is produced during the separation of the molten steel from impurities in the furnace, which is comprised of a complex.

Copper scrap is smelted in primary and secondary smelters. Type of furnace and process steps depend on copper content of the secondary raw material, other constituent, size, etc.

In the case investigation of landfill disposal of blast furnace slag from secondary lead smelters book oxide scrap material, reducing conditions are required, which can be achieved through carbon and iron along with fluxing agents.

Above one hundred secondary lead smelters devoted to lead-acid battery recycling are in operation in the world [1], and a major part of them are discarding significant tonnage of toxic slags or mattes to landfill, which represents a serious environmental problem and Cited by: 1.

Ground granulated blast furnace slag (GGBS) is a by-product from the blast-furnaces used to make iron. Blast-furnaces are fed with controlled mixture of iron-ore, coke and limestone, and operated. Also, secondary smelters were capable of processing demolition material from a house containing lead-based paint and sand-blasting material used on a bridge coated with lead-based paint A SURVEY OF LEAD BATTERY RECYCLING SITES AND SOIL REMEDIATION Thermal Treatment The Exide Corporation is developing a Super High Temperature Metals Cited by: Sham Recycling: established guidelines for what constitutes legitimate recycling and has described activities it con­ siders to be illegitimate or “sham recycling.” in making this determination in­ clude whether the secondary ma­ terial is effective for the claimed use, whether the secondary File Size: 80KB.

Primary lead production using the lead blast furnace in conventional practice is carried out using sinter feed. At YMG, China, the sinter plant has been replaced with a lead ISASMELT furnace. The ISASMELT furnace produces lead bullion plus a high-lead slag, which is cast into lumps to provide a suitable feed for the blast Size: 1MB.

Secondary lead smelting is a proven technology that reclaims lead from lead-acid battery waste sites. The Center for Hazardous Materials Research (CHMR) and Exide Corporation (Exide) have demonstrated the use of secondary lead smelting to reclaim usable lead from various types of waste materials from Superfund and other lead-containing sites.

This volume presents the proceedings of the International Conference on The Science and Engineering of Recycling for Environmental Protection (WASCON ), of which a number of themes have been identified. All are inter-related and inter-dependent in so far as potential users of secondary, recovered or recycled material have to be assured that the material is environmentally.

Chicago, Indiana, had operated as a primary and secondary smelting facility from until Sincethe primary product of USS Lead had been lead. Wastes which were produced during smelting operations are calcium sulfate sludge, blast furnace flue-dust, bag-house bags, rubber and plastic battery casings, and waste slag.

Blast Furnace Slag - Material Description ORIGIN In the production of iron, iron ore, iron scrap, and fluxes (limestone and/or dolomite) are charged into a blast furnace along with coke for fuel. The coke is combusted to produce carbon monoxide, which reduces the iron ore to a molten iron product.

Copper smelting slag is a solution of molten oxides created during the copper smelting and refining process, and about million tons of copper slag are generated annually in Korea.

The oxides in copper smelting slag include ferrous (FeO), ferric oxide (Fe2O3), silica (SiO2 from flux), alumina (AI2O3), calcia (CaO) and magnesia (MgO). The main oxides in copper slag, which are iron oxide and Author: Jei-Pil Wang, Urtnasan Erdenebold.

The Muldenhütten Recycling und Umwelttechnik (MRU), Freiberg, is the third largest smelter of lead in Germany. The smelter, established in the 14th century, was renovated to a secondary lead smelter in /, using state-of-the-art technology and since then continuously modernized.

From this time. In order to prevent leaching of potentially hazardous constituents from shot blast and cast house dusts, an alternative to simple land dumping or landfill is the treatment of these wastes with hydrated lime prior to disposal in a chemical landfill. One means of providing such treatment is to transfer the two waste materials to a storage bin.

Reports are not required for any 'quarter unless there have been periods of excess emissions. (Suggestions for format and content of recordkeeping on startup and shutdown operations and malfunctions are indicated in Table at the end of section ) The above provisions presently apply only to three furnace types at new secondary lead smelters.

A promising type of steel slag for applications is the ladle furnace (LF) slag, which is also known as the basic slag, the reducing slag, the white slag, and the secondary refining slag. The LF slag is a byproduct from further refining molten steel after coming out of a basic oxygen furnace (BOF) or an electric arc furnace (EAF).

The use of the LF slag in further applications requires Cited by: United States Environmental Protection Agency Industrial Environmental Research s Laboratory Cincinnati OH Research and Development EPA/S Mar.
