Abstract
Provided are a method and apparatus for treating a feed stream for a flotation device comprising a mechanical agitator in a tank, the feed stream comprising solid particles. The method comprises generating microbubbles in a diluation water stream, mixing the diluation water stream with the feed stream to facilitate attachment of the microbubbles to the solid particles in the feed stream and generate bubbles for attachment to microbubble-attached solid particles, and fluidly connecting the feed stream to the flotation device. The apparatus comprises a feed stream conduit fluidly connected to the flotation device, a diluation water stream conduit fluidly connected to the feed stream conduit for conveying the diluation water stream to the feed stream, and a microbubble generator connected to the diluation water stream conduit for generating microbubbles in the fluid stream.
