The pilot trial of detoxification of chromium slag in cyclone furnace and production of slag wool fibres were investigated in a power plant in China. 10–30 wt.% chromium slag was mixed with pulverized coal and 0–10 wt.% limestone as the raw materials of the cyclone furnace. ... A large number of industrial solid waste resources urgently ...





In case of GBFS production, maximum burden on the environment is due to BF slag production and the amount of electricity consumed (161 MJ/ton) during the granulation process. The influence of electricity sources on GBFS production was studied via scenario analysis. For investigation, solar and thermal electricity mixes were considered in 50:50 ...





The industrial use of waste in the production of geopolymer concrete will not only have economic and environmental benefits but will also solve the problems associated with the removal of large amounts of waste materials, such as coal-fired power plant ash and slag from the production of metals, which otherwise could endanger the environment.



Introduction. Air is heavily polluted by industrial emissions containing various harmful substances from the environment (sulfur, nitrogen, carbon, heavy metals, hydrocarbons, dust particles) in many regions of Ukraine.1 One of the sources of atmospheric pollution is a by-product of thermal power plants (TPP) and cogeneration plants (CP) that burn solid fuel.1 …





The quality of raw materials (iron ore, coal, and coke) has a clear impact on the carbon emissions of the hot metal production in steel making. So far, very little work has been done to measure and quantify this impact. Yet for benchmarking, technology choice and general carbon optimization are important elements. The total slag production of a blast furnace gives …





Steel slag, the main solid waste in the steel-making process, is produced more than 120 million tons annually in China.Most of the steel slag was stored in the open air, which brought potential safety and environmental protection risks such as land occupation and infiltration of heavy metal components into the soil. In recent years, the utilization and application of steel …

Nowadays, the application of biomass ash and slag to agricultural and forestry soils is generally considered as the best way [5]. Since biomass utilization technologies in the Nordic region are highly developed, lots of researches have been done on the utilization of ash and slag, especially in the field of soil improvement including fertilizing and on top of …



In 2015, the domestic overall production of calcium carbide was 26.5 million tons/a. Carbide slag is the waste generated during industrial production, which is hard to be treated. Around 75–85% of the generated calcium carbide is discharged, while the utilization rate of this kind of solid waste is less than 50% at present.

A recent attempt to employ industrial slag in thermal spray application was made by Kucuk et al. who deposited ferrochromium (FeCr) slag on AISI 420 substrates with APS method to evaluate its high temperature oxidation performance for use on caster rolls as an alternative to commercially available top coating feedstock materials [98 ...





Keywords: IGCC, slag, industrial waste, characterization, recycling 1. Introduction Gas installations of combined cycle (GICC) process are a fully different electrical power production process with energy obtained from burning a mixture of coal and coke coming from petroleum refining. In this new process, inorganic wastes are



Concurrently, the inert RO phase and the iron-calcium phase contained in the steel slag also formed a certain amount of C 4 AF, which contributed to the cementitious activity of the steel slag. The industrial production showed that the steel slag multi-phased clinker sintering technology had positive effect on the activity of the clinker (Cao ...



Use of blended cement with industrial by-products as supplementary cementitious materials is a sustainable alternative to carbon-intensive conventional cements.Although the potential of several new alternative cementitious materials has been reported in the literature, their industrial acceptance is minimal compared to fly ash and slag. In addition to performance …



The processing of coal slag typically involves crushing and screening of coal slag, and storing and/or bagging of finished product granules. In addition to receiving coal slag from a neighboring power plant, unprocessed coal slag may be delivered from coal-fired power plants in other areas of the United States for processing.





granulated slag. KIC Metaliks reported production of 19,400 tonnes of granulated slag. Sky Alloys & Power Pvt. Ltd reported production of 12,471 tonnes of MS Slag. Tata Steel reported production of 3,563,651 tonnes of BF Slag. The information regarding plant-wise capacity of iron and steel slag in the country is given in Table- 1.



Steel Slag (SS) mainly comes from the waste slag produced in the steelmaking process (Zhang et al., 2022a, Zhang et al., 2022b).The global production of steel slag can reach 150 to 250 million tons per year (Liu, G. et al., 2023).The accumulation of large quantities of SS will not only occupy a large amount of land resources, but also cause serious pollution of soil …







In order to assess the possibilities of using ferrous slags generated in Ghana, selected slag samples from some foundries have been characterized. A total of six bulk samples were collected from three different foundry shops to determine their chemical and mineralogical composition. ... Dvortsov, S.P., Shemonaeva, T.N., Strakhov, V.M ...







China is the largest producer and consumer of calcium carbide in the world. The calcium carbide industry is an indispensable industry to support the basic life of people. The huge production capacity of calcium carbide is accompanied by a large number of solid waste carbide slag. Due to the immature treatment technology of carbide slag, a large number of carbide slag are stacked …





Steel slag is the main solid waste generated in the steel-making process, accounting for 15 to 20% of crude steel output [1].China's crude steel output in 2021 was 1.035 billion tons [2], more than half of the global crude steel output (1.9505 billion tons) [3], and the steel slag output exceeded 120 million tons.In contrast, the comprehensive utilization rate of …









The robust nature of slag and the sometimes vast scale of production remains mean that iron production sites are generally easy to locate.11 Geophysical survey techniques such as gradiometry or resistivity can additionally be used to guide excavation strategies, to explore the depth and distribution of subsurface remains—for example, to ...
