As such, a "white gold" rush there fueled Europe's bombs in World War I and helped raise IQs once iodine deficiency was discovered. But even after the nitrate mines closed in the 1930s, the source ...

An UV–visible method was used to determine the concentration of iodine in the organic phase. The extraction and stripping rates (E, S) were calculated using the equations below: (1) E = V Org * C Org V F * C F × 100 % (2) S = V S * C S V Org * C Org × 100 % Where: C F: Concentrations of iodine in feed solution.. C Org: Concentrations of …

The mining sector's contribution to the country's 2022 GDP was 13.6 percent and mining exports reached 58 percent of total country exports. The industry remains a key sector of Chile's economy. The estimated price of copper for 2023 is $4.04 per pound. According to USGS, Chile lithium production output increased from 28,300 MT of lithium ...

CHILE – RB Energy of Vancouver is considering the sale of its Aguas Blancas iodine mine 95 SE of Antofagasta. Officially, the company believes the market is "not attributing appropriate value" to the project. A formal process to maximize the value of the asset will be undertaken, but selling is a possibility. If RB Energy sells Aguas Blancas ...
