3. The process as claimed in claim l wherein the molten metallic iron and molten slag are charged to a holding furnace to effect more complete separation and settling of metallic iron and phosphorus from the manganese-enriched molten slag produced in the electric furnace.
(3) high pressure roller mill screening full cut-off road magnetic separation, not only further abandons mine tailing, has improved the ore amount that enters to grind the grade of ore and follow-up ore grinding, and Relative grindability has improved more than 20%, has also further reduced model and the installed power of follow-up grinding attachment.

Compared to the classical Environmental Kuznets Curve (EKC) hypothesis with inverted U-shaped fitting curves , a linear relationship was observed between trace metal pollution and population and vehicle density in this study. Therefore, the control point during the urbanization process might be revealed which were related to the differences in urbanization gradients. Limited by data availability, the analysis in this study only concentrated on Chongqing, which might not present the overall trend between the socio-economic factors and trace metal pollution in China. In future work, ground-based monitoring datasets should be used to quantify the spatial pattern in a fairly long period and understand the relationships between trace metal accumulation and socio-economic variables. The result observed in this study might only present one stage of the U-shaped fitting curves in the EKC hypothesis.
Thus, the isotopic composition cannot be used alone for the characterization of graphite and discrimination of its origin [53,54]. The interaction of graphite with hydrothermal fluids did not modify isotopic compositions, even in the most transformed samples from mining sites, and differences in this case may reflect a different primary carbon source . Based on the carbon isotope (δ 13C) data and nitrogen content for microdiamonds obtained from peridotites and chromitites of the Luobusa ophiolite in southern Tibet and chromitites from the Ray-Iz ophiolite in the Polar Urals of Russia [15,50], it was concluded that those microdiamonds incorporated into the chromitites and peridotites near the MTZ and were transported to the shallow mantle depths at very fast rates. Furthermore, high-spatial-resolution carbon isotope analyses of natural graphite demonstrated isotopic heterogeneity within single graphite crystals in metamorphic rocks, attributed to the difference in diffusivity between 12C and 13C in the growth medium .With respect to the presence C-bearing minerals in ophiolites, the application of carbon isotopic composition in fluid-deposited graphite is an efficient tool used to understand the origin of carbon (organic matter, mantle, or carbonates), both in the shallow and deep earth environments, helping constrain the fluid history and the mechanisms involved in graphite deposition .8‰, in graphite from high-grade metapelitic rocks of the Anatectic Complex of Toledo (ACT), showed a biogenic origin . Also, chemical differences ranging from −20.5 to −27.1‰, similar to that of the original calcite that composed the sediments, indicating that, under reducing and low-temperature conditions, there is a mechanism to retain carbon during its transport into the deeper earth . Carbon stable isotopes on graphite from Alpine Corsica (France), formed during subduction metamorphism, showed δ13C values up to 0.8 ± 0. Although, in closed systems, carbon isotope systematics in graphite are mainly governed by Rayleigh precipitation and/or by changes in temperature, in open systems, in which carbon is episodically introduced along the fracture systems, the carbon isotope variations are more complex .
