red mud is not naturally occurring, but a by-product (read: waste) from an industrial process. Cite please I did cite it in Post #5. But I'll be fair and cite it once more: 2nd Source from Post #5: "Red mud remains as residue from the processing of bauxite using different methods. The chemical composition of red mud varies widely with respect to the types of bauxite ore and processing parameters. Red mud samples from Guizhou, China, were investigated using a X-ray fluorescence spectroscope, a quadrupole inductively coupled plasma mass spectrometer and a electron probe micro-analyzer. The results showed that red mud consisted of eight main chemical components--CaO, Al(2)O(3), SiO(2), Fe(2)O(3), TiO(2), Na(2)O, K(2)O and MgO--and dozens of trace elements, including natural radioactive elements, such as uranium and thorium. Gamma spectrometric analysis showed that the values of internal exposure index I (Ra) and external exposure index I (γ) of Guizhou red mud were 1.1-2.4 and 2.3-3.5 respectively. I spent 7 years as a chief analyst in a lab and one of my primary tools was X-Ray spectroscopy. The first 8 are clay minerals and relatively harmless. The important stuff is the trace elements. Does the article mention what they are. Cadmium, Lead, Mercury, etc. are harmful in the ppB range. Are they directly mentioned?
