Abstract
Described herein are methods of reducing the viscosity of products of sulfide ore froth flotation. A froth overflow, or an underflow of sulfide ore flotation is treated using a nonionic compound to reduce the viscosity of a froth or an underflow. The lowered viscosity imparts several benefits in sulfide ore processing of copper and molybdenum metal products, including increased rate of sedimentation to yield a concentrated product.
