kalau aku pun pilih rare earth....
Rare Earth Elements – your iPhone depends on it!

Just one of the REMs
So you’ve seen it in the headlines — the U.S. has uncovered an estimated $1 trillion worth of minerals in Afghanistan. Besides iron and copper (largest mineral deposits discovered), there are deposits of niobium, a soft metal used in producing superconducting steel, lithium, gold, copper, and rare earth elements (REEs).
If your chemistry is as rusty as mine, here’s a brief run-down on REEs:
They are a family of 17 chemically similar metallic elements, including lanthanum, cerium, neodymium, europium and yttrium, used in nearly every electronic device2 essential in building “green” technologies3 and necessary for military applications.4
That will satisfy some of you. For readers looking for a little more detail on this subject, continue reading as we provide a rare (pun intended) in-depth explanation of a dinner topic.
Common abbreviations used when referring to rare earth materials:
RE = rare earth
REM = rare earth metals
REE = rare earth elements
REO = rare earth oxides
LREE = light rare earth elements (La-Sm)
HREE = heavy rare earth elements (Eu-Lu)
While REEs are relatively abundant in the earth’s crust, finding deposits significant enough to mine is less common. China has been the dominant provider (~95% of world’s supply) of rare earth materials since the 1990s by cornering the market with the sheer scale of their production. The extraction and refinement of rare earth metals can cost anywhere between $500 million to $1 billion per mine and separation plantaccording to Jim Hedrick, a former USGS rare earth specialist.
Due to increasing global demand and diminishing supply, China has been lowering its export quotas for rare-earth metals by about 6% annually since 2000 and are expected to completely ban the exportation of REEs by 2015.
Although China is the dominant provider, it has only ~54% of the world’s rare earth deposits. The U.S., Canada, and Australia have large known RE deposits and mining developments are underway in those countries.
Companies of note:
Molycorp Minerals LLC – Possessing one of the largest, richest RE mines in the world (Mountain Pass, CA), it was closed back in the late ’90s but is projected to re-open in 2011.
Avalon Rare Metals- 100%-owned Nechalacho Deposit (Thor Lake, Northwest Territories, Canada), these deposits contain the more valuable ‘heavy’ rare earths. Lynas Corporation Limited- A concentration plant is scheduled for completion by the end of this year in Mt Weld, Western Australia. A materials processing plant should start production in late 2011 in Kuantan, Malaysia.
kat ostolia nun...penduduk yg duk sepanjang jalan yg lori ngangkut bijih nak htr ke pelabuhan pun buat piket..tak kasi lalu depan umah depa...padahal katanya bijih tu takde le beradioktif pun..
ni kita yg sah2 sisa bahan buangan yg mmg beradioaktif akan disimpan di sini dgn senang hati nak terima...?
nampak tak org yg ada kesedaran dgn org yg pikir $$$ jah?

peach...bijih timah mmg bahaya sebenarnya...sebab mudah kena lung cancer....tapi di malaysia ni...kita tak anggap faktor tersebut penting...contohnya di dengkil....bijih timah ni berlonggok macam bukit...berdekatan dengan kampung berdekatan...dekat juga ngan kuarters pekerja bijih disitu...
13 June 2010 : Former premier Dr. Mahathir Mohamad disagreed with the proposal for Malaysia to build nuclear power plants and reported that “a small amount” of nuclear waste was buried in Perak.
Mahathir said, “In Malaysia, we do have nuclear waste which perhaps the public is not aware of. We had to bury the amang (tin tailings) in Perak, deep in the ground. But the place is still not safe. Almost one square mile of that area is dangerous.”
Following his remarks, The Star has discovered that 80,000 200-litre drums containing radioactive waste are currently being kept at the dump located in the Kledang Range behind Papan town. The site is about 3km from Bukit Merah and Papan and about 15km from Ipoh. And the waste is thorium hydroxide, not amang.
In fact, it is only January this year that work finally began on the building of a proper underground storage facility called an engineered cell (EC).
The ongoing cleanup of the 30-year-old problem is estimated to cost a massive RM300 million.
tapi itu zaman.. sume kata selamat
5 June 1984 : The Prime Minister Datuk Seri Dr Mahathir Mohamad says the government has taken every precaution to ensure safety and that construction of the radioactive dump in Papan will go ahead.
28 June 1984 : The Minister of Science, Technology and Environment, Datuk Amar Stephen Yong, states that the Papan dump is safe because it is being built according to stringent standards. He challenges critics to prove that the dump will be hazardous to health and the environment. In the meanwhile, ARE continues operating, dumping the thorium waste into an open field and pond next to the factory.

bijih timah apa plak...saya cakap pasal bijih rare earth tu...tanah yg depa lombong akan dibawa dgn lori/train ke pelabuhan untuk dibawa ke malaysia...
gigih tu..
org ostolia dah rejek...kita plak dgn senang hati terima..$$$$$$$$ punya pasal..
mcm manami kata..dah takde investor lain ke yg kita kelapar sgt terima investor ni?
