Galena Flotation Sphalerite

Galena - Sphalerite Flotation & Separation …

The lead and zinc flotation was conducted in “Sub-A” Flotation Machines which provides for the maximum grade of concentrates and the maximum flexibility for the continuous retreatment of the cleaner middlings.

Lead activation of sphalerite during galena …

The galena flotation was fast for the first three minutes and tapered off afterwards. After the first 3 or 4 minutes of flotation time, the rate of galena flotation was sufficiently reduced that it became comparable to the rate of sphalerite flotation.
