Dysprosium
Dysprosium article has 4 Internal Contradictions.

1.  Dysprosium has relatively few applications where it cannot be replaced by other chemical elements. {**Wait! The Production paragraph, below, mentions the "lack of any immediately suitable replacement"...}

2.  About 100 tonnes of dysprosium are produced worldwide each year,.... with 99% of that total produced in China. {**Wait! That means only 1 tonne is produced outside China, but Australia produces 50 tonnes, according to very next paragraph...}

3.  Australia is producing 50 tonnes (49 long tons)...   {**Wait! 50 tonnes does NOT equal 49 long tons.}

4. ....most dysprosium is being obtained from the ion-adsorption clay ores.... {**Wait, another paragraph sez:  Dysprosium is obtained primarily from monazite sand, a mixture of various phosphates.}   Dunno much about clay and sand, but they AIN'T the same....

Note: I am not knowledgable about Dysprosium, and cannot say what parts of these statements are correct. They do seem to contradict themselves, tho...

Note: Too busy right now to research the facts / fix & update the Dysprosium article.... Sorry!

Note: This is the 1st time I've posted to a Talk page.... Feel free to Clue me in....!
