Stratagem on Tellurium Recovery from An Unique Independent Tellurium Ore Deposit in the World by Biohydrometallurgy

Based on a the investigation of the scattered elemental tellurium Deposit located in Dashuigou,Sichuan province,P.R.of China,Te revovery processes from incidental tellurium products or materished materials around the world and reacently reseaches in our country from independent tellurium ores were reviewed.Finally,researches on utilization processes using biohydrometallurgy from the low-grade Te ores have greatly advantages to enlarge the resource scales and to increase the value in use of tellurium reserves.The mechanism studies on Te recovery from sulfide type using biohydrometallurgy is not only with significance of acdemic theoretics but also is the base of succeeful exploitation for blooming local economies.
