A review on lead slag generation, characteristics, and ...

Lead slag is produced by the primary and secondary lead industry. The large amount of lead slag discharge causes environmental problems. Reducing the toxicity and increasing utilization of lead slag are important measures to solve the negative impact of lead slag on the environment.

LEACHING PROPERTIES OF SECONDARY LEAD SLAG …

LEAD SLAG STABILIZED/SOLIDIFIED WITH CEMENT AND SELECTED ADDITIVES 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 ...

Utilization of secondary lead slag as construction ...

Secondary lead slag, a waste product from battery smelting using CaCO 3 as flux, has been investigated for its use as an admixture and/or aggregate in the production of concrete blocks. The slag was added as partial replacements of cement and/or aggregate. The results revealed that the oxide components of the slag were similar to those of ordinary Portland cement (OPC).

Assessment of Leaching Characteristics of Solidified ...

leaching time (12 years) limited the utilization of lead slag as construction materials according to the study of Ettler et al. [14]. However, Saikia et al. [15] confirmed the indication that the lead slag from primary lead production could be used as a partial replacement of fine aggregates in cement

Utilization of secondary lead slag as construction material

The lead slag generated from lead smelting and from recycling of secondary lead batteries suggest that this slag can be used as fine and coarse aggregate in the preparation of cement mortar and ...

Preliminary Study of the Use of a Secondary Lead Smelting ...

Jan 01, 2018 · In this work, the preliminary study about the use of secondary lead smelting slag (SLSS) as an addition to Portland cement is presented. SLSS is a waste from a Colombian secondary lead smelter. The chemical, physical and mineralogical characteristics of the raw materials were evaluated by X-ray fluorescence, particle size and X-ray diffraction.

Primary and Secondary Smelting Operations

Lead dust and smoke can be released during all of these processes, and slag contaminated with lead particles may be left over after smelting. The Secondary Smelting Process Secondary smelting of lead is similar to primary smelting, but does not require the initial sintering process.

Slag Cement EPD

The growing need to understand the true impact of a products impact on the environment has lead the SCA to assist in creating an Environmental Product Declaration (EPD) for slag cement. The EPD provides quantifiable environmental data on the materials, transportation and processing impacts in the production of slag cement. View the full EPD below:

Common Uses for Slag | National Slag Association

Slags can be broadly categorized as ferrous (iron/steel) and non-ferrous (copper, lead/zinc) depending on the industry from which they come.

Jul 12, 2019 · Secondary alkaline lead slag (SALS), generated during lead–acid batteries recycling, is a hazardous waste due to its high reactivity, solubility, and migration of toxic elements. After pulverization...

Ground granulated blast-furnace slag - Wikipedia

Ground-granulated blast-furnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.

What is slag cement

Slag cement is commonly found in ready-mixed concrete, precast concrete, masonry, soil cement and high temperature resistant building products. While there are many applications and benefits of slag cement, a few are highlighted below and detailed information sheets are located here.
