Aktigiruq and Anarraaq, deposits on adjacent state land about five miles (eight kilometers) northwest of the Red Dog mill, are a likely source of this future ore. Among the largest undeveloped zinc deposits on Earth, Aktigiruq has the potential to deliver ore to the Red Dog mill for 25 to 50 years beyond 2031, at current production rates.

by water and deposited in the nearest valley sometimes building up two to three feet of mine dirt and changing the stream's course. At the mill, ores were crushed and washed. Tiny particles blew into the air. Zinc ore contains zinc and sulfur and is often mixed with pyrite, which is a combination of iron and sulfur.
The resulting fine particles and water form a slurry that flows from the mill to flotation cells or tanks. Inside these tanks, the slurry is agitated by beaters in the presence of chemical reagents, creating a suspension of air bubbles. ...
