Products

Massive trucks carry the ore to a crusher that breaks the rock into pieces less than 10 inches in diameter. The crushed ore then travels five miles by conveyer belt to the concentrator. There, we mix the ore with an aqueous solution and grind it into a fine powder. We then mix the ore powder with water, chemicals and air in flotation cells.
