Report studies mining’s use of chemicals

Last year, the North American mining industry spent more than $1 billion(US) for the 15 billion pounds of chemicals it used in the extraction, beneficiation and transportation of ores. Alumina processors were the greatest user of chemicals with expenditures of $215 million, followed by processors of molybdenum at $206 million and copper at $151 million.

The struggle to increase efficiency has forced mining companies to look at new extraction technologies to remain competitive. Solvent extraction, hydrometallurgy and liquid ion exchange demand new chemical reagents that can improve yields and lower costs, especially for low grade ores.

The need to minimize the environmental effects of ore processing has also stirred the search for new, less toxic chemical reagents.
