As to the progresses of tellurium recovery in a long time was based on the second-hand raw materials such as from the anode mud of metal smelting plants as the semifinished materials when other metals produced for lacking the independent tellurium deposit resources in the world [3].
Materials and Bacterial Culture X-ray diffraction, scanning electron microscopy, and X-ray probe analysis were employed in the mineralogical identification of the ores.

The design concept and material of underground waterproof stay updated.
Therefore, through research, we introduce more new waterproof materials - natural sodium bentonite waterproof blanket, physical and mechanical properties are shown in Table 1.
Supporting the use of bentonite blanket materials include particles of bentonite, bentonite sealant, sealing layering, concrete nails and iron gasket.
