Main Forum•Cudeco's Tellerium (TE) One of the RAREST elements
-
WILGAR REVERSE CIRCULATION (RC) DRILL PROGRAMME INTERSECTS HIGH GRADE GOLD, SILVER AND MOLYBDENUM CONFIRMS MINERALISATION CONTINUES BELOW SUBCROP Intersections include;
Gold up to 58.2 g/t Au (1.2oz/t)
Silver up to 1,090g/t Ag (35 oz/t)
Molybdenum up to 5,850ppm Mo (0.59%)
Tellurium up to 700ppm Te (rare element)

So just what is the significance of CDU's 700 ppm Tellerium?- Its abundance is about 1 µg/kg. In comparison, even the rarest of the lanthanides have crustal abundances of 500 µg/kg
The year-end price for tellurium in 2000 was US$14 per pound. In recent years, the tellurium price was driven up by increased demand and limited supply, reaching as high as US$100 per pound in 2006.
- The largest consumer of tellurium is metallurgy, where it is used in iron, copper and lead alloys. When added to stainless steel and copper it makes these metals more machinable. It is alloyed into cast iron for promoting chill for spectroscopic purposes, as the presence of electrically conductive free graphite tends to deleteriously affect spark emission testing results. In lead it improves strength and durability and decreases the corrosive action of sulfuric acid
Semiconductor and electronic industry uses include:Tellurium is used in cadmium telluride (CdTe) solar panels. National Renewable Energy Laboratory lab tests using this material achieved some of the highest efficiencies for solar cell electric power generation. Massive commercial production of CdTe solar panels by First Solar in recent years has significantly increased tellurium demand
Tellurium as a tellurium suboxide is used in the media layer of several types of rewritable optical discs, including ReWritable Compact Discs (CD-RW), ReWritable Digital Video Discs (DVD-RW) and ReWritable Blu-ray Discs.
- Its abundance is about 1 µg/kg. In comparison, even the rarest of the lanthanides have crustal abundances of 500 µg/kg
