“…Also, globalization surges the intensity of economic activities like trade and transportation, which demands more resources for their production of goods and services (Plank et al, 2018). All these economic activities put demand pressure on natural resources, as literature shows that trade improvements have a positive impact on material consumption Li et al, 2018;Schaffartzik et al, 2014;Wang et al, 2019). Thus, global economies are concerned to find out different ways to reduce resource depletion and associated CO2 emissions.…”

“…However, from 2007 to 2017, the structure effect became the inhibiting effect, especially from 2007 to 2012, reducing the ferrous metal consumption embodied in imports and exports for 61.99 million tons and 105.95 million tons, respectively. This may be due to the optimization of the import and export commodity structure, which had shifted from resource-based products to medium or high tech-based products ( Li et al, 2018 ). The change trend of the structure effect on embodied non-ferrous metal consumption was similar to that of ferrous metal, while the effect was smaller, increased by 41.45 million tons in imports and 4.17 million tons in exports.…”

“…Based on the study, the following policy implementations are provided. Due to the large imports and exports of products and services, net import of embodied metal can partially mitigate the situation of limited domestic resources ( Li et al, 2018 ). Therefore, excessive trade surplus is not beneficial to save embodied metal resources.…”

“…This is especially important for developing countries with high dependence on foreign trade, such as China. On the one hand, China's large metal consumption is not entirely for domestic use ( Li et al, 2018 ). Through exports, metals used indirectly for the production of exported products are massively consumed abroad ( Wang et al, 2019 ; Feng et al, 2019 ).…”

What drives embodied metal consumption in China's imports and exports

2020

The expansion of trade has not only increased imports and exports, but also increased metal consumption embodied in them. Based on China's input-output tables from 1997 to 2017, this study uses structural decomposition analysis (SDA) to analyze China's consumption of embodied metal in imports and exports in each sector, and identify their driving factors at the holistic, industrial and sub-sectoral levels. The results show the following. 1) China is a net importer of embodied ferrous metal and a net exporter of embodied non-ferrous metal, and the change of the embodied metal consumption showed an inverted U-shape. 2) The scale effect was the main driver for these increases; the technology and intensity effect were the primary inhibitor of embodied ferrous and non-ferrous metal consumption, respectively; the structure effect increased metal consumption embodied in imports more than in export. 3) Industry contributed most to the consumption, and the factors were heterogeneous in different industrial sub-sectors: the inhibitory effect of technology was more obvious in imports than in exports, and the structure effect promoted more embodied ferrous metal consumption import and more non-ferrous metal consumption export; the intensity effect was promoter before 2007 while its inhibitory effect became more obvious after 2012.4) China's technology level and metal utilization efficiency were still lower than those in foreign countries; the effect of technology to reduce embodied metal consumption was small but had potential impact. Based on these results, relative policy recommendations are proposed.

Introduction. Trends in developing Ukraine’s metallurgy in the context of using its mineral raw base indicate prospects for mining hematite quartzite deposits. Problem Statement. The problem of producing high-quality hematite ore concentrates is associated with the fact that aggregates of martite, goethite, marshallit quartz, and other low hard minerals can be easily reground while crushing and grinding. This results in increased content of fine particles (slimes), which decreases selectivity of separating ore and non-metallic minerals. One of the ways to solve this problem is gentle ore grinding Purpose. Developing a technology of dry and wet concentration for hematite quartzite from Kryvyi Rih Iron Ore Basin. Materials and Methods. While conducting the research, a set of methods are used including generalization of research data; chemical and mineral analysis of ore and concentration products prior to and after concentrating by magnetite and gravitation methods; mathematical modeling of processes; technological testing in laboratory and industrial conditions. Results. Magnetic and gravitation separation is used for hematite ore concentration. Sintering ore with Fe content of 55.1% and concentrates of 62.32-64.69% Fe have been produced from hematite ore. Iron extraction in marketable products makes up 73.6-80.49%. Conclusions. There have been developed technologies for dry and wet concentration for hematite quartzites of Kryvyi Rih Iron Ore Basin. For the first time, magnetic separation has been suggested to be used for hematite ore concentration. This has enabled producing concentrates with an iron content over 64.0%, decreasing ore grinding front by at least 40% as compared with the initial one, and reducing operation and capital expenses by over 30%.
