danger signals from china , page-9

Old information and much is now changing in Indonesia as far as politics is concerned, but answers your question...

"Mining Indonesia - Iron ore was found in sizable quantities, but was commercially exploited only in central Java"

"As the world's fourth most populous country, Indonesia could become one of the largest steel-consuming countries."

Without researching it too much I believe Indonesia currently has an export ban of sorts on iron ore, more revenue raising lol. They also mine iron ore now in Kalimantan with Putra Mining.

"Indonesia Iron Ore began exported in large volume in 2003. In 2005, estimated 1,000,000MT of Indonesia Iron ore of various grades entered the China market."
