The new froth cone and outer crowder maximizes froth recovery and creates a thicker, more stable, and more productive froth. Both the cone and crowder push the froth towards the center launder. This is especially important near the end of the circuit, after all the fast floating and well-liberated particles have been reported to the launders.

The froth must be promptly collected to the launder lip to maximize froth recovery. Optimal flotation recovery is achieved when these two processes work efficiently in harmony. The center launder upgrade is composed of three parts: ... after all the fast floating and well-liberated particles have been reported to the launders.

A laboratory study was conducted to evaluate and compare the effectiveness of nine different frother types when used in a three-phase, continuously operating froth flotation system. The frothers included several that are commonly used in the industry (e.g., MIBC, 2EH, and F-1) as well as unique frother types (e.g., F-3). The …

Entrainment is a process by which fine and ultrafine particles are transferred to the flotation froth from the top of the flotation pulp, and eventually discharge to the concentrate product, even when they are not attached to gas bubbles. Therefore, entrainment can be considered as a two-step process, one at the upper layer of the pulp …
