RE: boron Read the bottom of the news releases-
- Market prices reflect both the relative scarcity of borates and strengthening demand, with current prices for new South American contracts reaching highs of: US$730/tonne for colemanite (40 percent B2O3); US$697/tonne for ulexite (40 percent B2O3); US$1460/tonne for boric acid.
