Owing to the low grade, poor endowment and low output of copper and iron ore resources in China, domestic copper ore and iron ore are difficult to meet the needs of industrial development, which leads to the continuous rise of annual imports of copper ore and iron ore (Y. Liao et al., 2017; Shi et al., 2020). In 2021, China imported 23.404 ...

Low-grade papillary adenocarcinoma (LGPA) represents a relatively rare histological variant of polymorphous low-grade adenocarcinoma (PLGA). There has been a debate as to whether LGPA is associated with greater aggressive potential compared to PLGA; this is further obfuscated by the fact that diagnostic criteria for LGPA have not been well-defined.

The MMVT-hydrocyclone was able to effectively separate Si-Mg impurities from the low-grade phosphate ore with significantly lower energy consumption and higher efficiency and precision. Specifically, the separation efficiency increased from 76 % to 92 %, while the precision increased from 70 % to 87 %.

It can be seen that under Mode A and Mode C, more quartz and low-grade intergrowth (φ = 25%) particles enter the area of the concentrates, which reduces the grade and separating efficiency. In Mode B, there is a good result in the removal of low-grade intergrowth particles, however, it requires a large airflow rate (0.06m 3 /s) according to ...

Therefore, it is important to develop the new cost-effective processes that can efficiently separate and recover various valuable metals from low-grade REE–Nb–Fe ore. In China, the Nb in Bayan Obo ore is first reduced with hot metal in a blast furnace and then selectively oxidized in a converter ( Wei, 1988, Jin et al., 2014 ).

The physical and chemical properties of feldspar and quartz are highly similar, thus they cannot be easily separated effectively. In this work, the flotation separation of feldspar from quartz using sodium fluosilicate (Na2SiF6; SF) as a selective depressant was investigated. Moreover, the influence mechanism of SF on the selective flotation …
