The waste characterization included the sulphidic slag containing varying quantities of lead (total lead content and TCLP), along with the gaseous analysis (SO2, TSP and PPb). Through process improvement, we reduced both the quantity of slag produced and the lead loss to the slag, as well as the concentrations of gas pollutants in the gaseous ...
The use of steel slag as an aggregate is considered a standard practice in many jurisdictions, with applications that include its use in granular base, embankments, engineered fill, highway shoulders, and hot mix asphalt pavement. Blast furnace slag products have been used successfully in virtually all phases of bridge construction.
May 25, 2016· A life cycle analysis suggests that the use of ferronickel slag at a rate of 5% reduces the CO 2 emission from a tonne of Cem I cement from 839kg/t to 797 827kg/t, depending on the classification of the slag as either a byproduct or as a waste and hence whether the environmental impact of the slag is ''carried'' with the byproduct or ...
Lead scrap includes leadacid batteries, cable coverings, pipes, sheets and lead coated, or terne bearing, metals. Solder, product waste and dross may also be recovered for its small lead content. Most secondary lead is used in batteries. To recover lead from a battery, the battery is broken and the components are classified.
Use of LD slag has been shown to increase the soil pH. Experiments have found that application of LD increased the soil pH linearly. The soil pH increased from to with the use of 7500Kg of slag/hectare, the second year response being higher 41% increase in soil pH with 3000Kg slag/hectare (Pinto et al., 1995).
May 09, 2018· The importance of Ground Granulated Blast Furnace Slag (GGBS) lies in its greener way to become a substitute in concrete material. GGBS being a waste material, it needs proper method for disposal. So incorporating this waste material in concrete can reduce the depletion of conventional concrete components
Lead dust may be emitted when depositing dross into a waste container. Emissions may be released while charging dross to the storage bin via pneumatic conveyance system. Lead dust may be spilled and emitted while handling, transporting, and storing dross. Eliminate or minimize the use of manual drossing.
Recycling slag minimizes waste and disposal costs, reduces energy use, extends furnace life, and lowers the amount of additives needed to make slag. The concerns with slag recycling are that first, because slag can contain environmentally hazardous materials, it must be analyzed for elemental composition before reuse.
blast furnace slag. The waste material is neutral and nonhazardous in nature as per Chemical analysis report of CPCB (hazardous waste rules,2008, ). The quantity of generation of this slag is around 24 lacs MT per year from different steel industries in India(CRRI,2010). Presently, this steel slag isn''t utilised and is dumped near
India: Transport Minister Nitin Gadkari has promoted the use of ''waste'' materials such as slag cement for the construction of roads.
