In this pape1~ the XRT sorting technology and the results of a number X-ray transmission sorting of tLmgsten ore 247 of test runs conducted on tungsten ore, from Wolfram Camp Mine, are described. The aim of the test work was pre-concentration of the ore. 2 The functional principle of XRT-sortingW is extracted from the tungsten ore generally by alkaline high-temperature roasting and leaching (Gong et al., 2019), producing a large amount of tungsten ore processing residue (TOPR) (Jing et al., 2018). However, due to the limitation of extraction procedure towards W, part of W still remains in the solid residue (Zhong et al., 2015).Speciation, leachability and bioaccessibility of tungsten in tungsten

Heavy metal pollution is one of the major agronomic challenges. Tungsten (W) exposure leads to its accumulation in plants, which in turn reduces plant growth, inhibits photosynthesis and induces oxidative damage. In addition, the predicted increase in CO2 could boost plant growth under both optimal and heavy metal stress conditions. The aim
