This study aims to produce an eco-friendly white cement clinker by incorporation of celesto-barite mine waste. Samples of synthesized pure Monoclinic-C 3 S, Cubic-C 3 A and raw-mix were dried, ground to a Blaine of 3200cm 2 .g À1, doped separately with crescent amounts of mine waste and pure BaO (5 and 3% respectively), then burned at increasing …

Rao et al. discussed the rapid depletion of cement-grade carbonate as a result of continuous mining operations and high demand for industrial raw materials for paint, animal feed, oil well mud ...

The cement manufacturing industry has played a fundamental role in global economic development, but its production is a major facilitator to anthropogenic CO2 release and solid waste generation.

The main energy consumption of lime production is located in the calcination process and accounts for more than 90% of the total energy consumption [1]. The fuel consumed during calcination represents ca. 50% of the production costs of lime [2]. The calcination stage also accounts for 99% of the impact of lime production on global warming [1].

Results of IMPACT 2002+ analysis showed that per 1 ton crushed limestone rock production, the total depletion of resource and GHGs emissions were 79.6 MJ and 2.76 kg CO2 eq., respectively. Regarding to the four damage categories, 'resources' and 'climate change' categories were the two greatest environmental …

The production of commercial limestone typically exceeds production of all other stone types, although granite production has surpassed limestone production on occasion …

1. Introduction. The production of lime and cement is responsible for around 8 % of global anthropogenic CO 2 emissions (Andrew, 2018).About 65 % of these emissions are associated with the calcination of limestone (IEA, 2020; Schorcht et al., 2013) and can only be avoided with carbon capture.There are many carbon capture …

crushed limestone rock production, the total depletion of resource and GHGs emissions were 79.6 MJ and 2.76 kg CO 2 eq., respectively. Regarding to the four damage categories, 'resources' and 'climate change' categories were the two greatest environmental impacts of the limestone rock production.

Environmental Impact Assessment (EIA) is a prominent technology to assess the environmental changes in the open cast Limestone mining region. However, traditional EIA methods and Limestone deposit identification involves time consuming, cost effective and manpower requirements. We cope-up these problem and incorporated with …

A low grade siliceous limestone sample from the Jayantipuram mine of Andhra Pradesh, India, has been investigated for its suitability for cement making. Petrological as well as X-ray diffraction pattern studies indicated that the limestone sample was crystalline and dominantly composed of calcite and quartz. They are simple in …

As the demand for cement supply is continually growing, this causes an increase in the use of aggregate, especially limestone since it is important in the production of Portland cement [13], [14].Exhaustion of the earth's non-renewable resources is a growing dilemma when the reason is that the energy consumption has …

1 online resource (xvii, 455 pages) : Modern uses of traditional materials. 'Lime and Limestone' is a comprehensive and up-to-date presentation of the main scientific and technological aspects of the quarrying, processing, calcining and slaking of lime and limestone products.

Limestone is an essential raw material for cement production. To meet the growing demand, several new mines have come up in the recent years. Limestone mining activities lead to environmental ...

The cement manufacturing industry has played a fundamental role in global economic development, but its production is a major facilitator to anthropogenic CO2 release and solid waste generation. Nigeria has the largest cement industry in West Africa, with an aggregate capacity of 58.9 million metric tonnes (MMT) per year. The Ministry …

be used (915 kg/Mg (1830 lb/ton) lime produced for dolomitic limestone and 785 kg/Mg (1570 lb/ton) lime produced for calcitic limestone). These estimates are theoretical, based on the production of two moles of CO 2 for each mole of limestone produced. In some facilities a portion of the CO 2 generated is recovered for use in sugar refining.

Environmental Impact Assessment (EIA) is a superior tool use for assessing environmental changes in the opencast limestone mining region. In mining and its development, there is currently pervasive global concern focused on the need to move the mining sector to a more sustainable environment. In limestone mining, the waste …
