How Does Coltan Mining Affect The Environment?

2022-2-3  How Does Coltan Mining Affect People? In mines that mine iltains (most of them being young), Coltan remains in the atmosphere for a long time. Young artisans working in the coltan mining industry risk high occupational exposure to radioactivity after performing this study, due to working conditions and exposure to the radioactive material that they experience.
