The major waste by product from steel production is slag at 79.15% as shown in 1. Steps have been taken all over the world to generate new ways of recycling or to reuse slag material. Advances have made it plausible to separate metallic scrap and lime in the slag.
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 P-Pb). 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 second stage involves the reduction of the slag using a carbon-based reducing agent. Sodium carbonate ('soda ash') or calcium carbonate is also added as a 'flux' to help form the slag of impurities. Lead oxides, lead sulfate and any antimony oxides are reduced, and the result is 'antimonial lead', which may also contain some bismuth and silver.

India: Transport Minister Nitin Gadkari has promoted the use of 'waste' materials such as slag cement for the construction of roads. He said that the ministry has decided to build concrete highways in the place of traditional bitumen roads, in comments to local press at a 'Make In India' campaign event.
Key words: secondary lead, slag, stabilization, solidification, leaching, TCLP Introduction Lead is one of the essential and most widely used metals in the world. From the whole lead production in Europe up to 70 % of lead is used in battery industry and scrap automotive batteries are a major source of secondary lead. Also, the secondary refining

waste at source and the provision of facilities in which the wastes can be processed to recover recyclable constituents present in them are not commonplace. Fears that wastes may be contaminated with other materials which could lead to widespread pollution if they were recycled have been stated, particularly in respect of liability.

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.
Lead and zinc are often related as coproducts in both source and metallurgical treatments, and the various combinations of slags, which include lead, lead-zinc, and zinc, are similarly produced. Figure 11-1 presents a general schematic depicting the slag production process for copper, nickel, and lead .
Fly Ash – The scrubbers in the flue use a lime slurry to reduce the amount of sulfur dioxide (SO 2) escaping to the atmosphere and other toxic materials. Arsenic, cadmium, copper, gallium, lead, antimony, selenium, zinc and other chemicals are commonly found to concentrate in fly ash.
The utilization of solid waste is the challenge for the civil and environmental engineers to utilize the waste from different industry to excel the sustainable development, and in the same time, it is matching with the cost concern of the present materials. Copper slag is a by-product obtained during smelting and refining of copper.
blast furnace slag. The waste material is neutral and non-hazardous in nature as per Chemical analysis report of CPCB (hazardous waste rules,2008, ref.no-19). 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
May 25, 2016· A life cycle analysis suggests that the use of ferro-nickel slag at a rate of 5% reduces the CO 2 emission from a tonne of Cem I 52.5 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 by-product or ...

Electronic waste, or e-waste, is an emerging problem with developed nations as with developing nations. In the absence of proper collection and disposal systems, awareness, and proper regulations, the problem is rather more acute in developing nations. These wastes are environmentally hazardous on one hand and valuable on the other. They contain substantial amount of metal value, including ...
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.
