Argentina tripled lithium carbonate production capacity in last two years
Argentina, the world's No. 4 lithium producer, has four projects in production.
Peruvian presidential front-runner Alejandro Toledo said on Wednesday if elected he would talk with extractive industries about possibly introducing a tax on windfall profits as commodities prices surge.
Toledo, who in his first term from 2001 to 2006 helped lure billions in foreign investment to Peru, said voters need to see concrete benefits from mining, oil and gas activity.
