Chemours said its mining division, which is one of the largest North American producers of solid sodium cyanide, was being considered for a sale drive due to a shift in portfolio focus.

"Optimising and focusing our portfolio continues to be a top strategic priority for Chemours," said Mark Vergnano, Chemours president and CEO. 

"Our overall goal and intent are to position every one of our businesses—including Mining Solutions—to deliver the highest level of profitable growth possible, for the benefit of all our stakeholders."

Ed Sparks, Chemours Titanium Technologies and Chemical Solutions president noted that recent investments in production capability and infrastructure at the company's Memphis plant, along with supply chain optimisation efforts, have increased the value of the Mining Solutions division.

"The Mining Solutions business remains committed to addressing the ever-changing needs of the precious metals mining industry, throughout and following this strategic review," said Sparks.

Chemours is also operating in the rare earths space - it announced last December that it would supply Energy Fuels with at least 2,500 tons a year of monazite ore.
