during the course of our studies on archaeometallurgy in southeastern iran, we tried to survey the triangle of the sirdjān, neiriz and shahr- e- bābak. as a result, remains of old iron mining residues of smelting furnaces, and iron smelting slag heaps were observed and recorded. a few samples of iron ore and smelting slag have been analysed classically and instrumentally. according to the acq...

We reviewed specific chemical exposures and exposure assessment methods relating to published and unpublished epidemiological studies in the alumina and primary aluminium industry. Our focus was to review limitations in the current literature and make recommendations for future research. Although some of the exposures in the smelting of aluminium have been well characterised, particularly in po...

smelting of hammerable iron and its treatment in antiquity and Medieval produced also by-product: slag. Because of small yields of iron the process produced only small amounts of slag that did not attract attention of smelters concerning its possible use. the use of slag pieces was only accidental. a lot of slag pieces and blocks from slag pit shaft furnaces were used as a material for mound bu...

the design and manufacture of direct smelting reactors depends on the rate of the physico-chemical reactions that occur in the particles immersed into the molten bath. investigation of the effects of the important parameters that influence the smelting rate of the particles that in the furnace are both difficult and expensive if the aimed is to take measure meuts under real practical conditions...

Xinjiang’s industrial sector accounted for more than 80% of the total energy-related carbon emissions. A further understanding of each industrial sub-sector’s carbon intensity is very necessary to make differentiated policies and measures. This paper applied index decomposition analysis and attribution analysis to examine the influencing factors and each sub-sector’s contributions to the change...
