The quest is to optimize the separation between the lead and zinc, with maximum recoveries and grades, and to limit the use of cyanide as depressant for the sphalerite during the galena flotation.

Silver Lead Zinc Ore Processing Method using Flotation

2016-4-20 · Silver, Lead & Zinc Flotation Circuit #2. The recovery of silver minerals occurring in a lead-zinc sulfide ore is efficiently accomplished using the above flowsheet. The process consists of selective flotation to produce a mixed silver-lead concentrate

Physicochemical studies of oxide zinc mineral flotation

2016-9-29 · Regarding the mixed collector flotation, the recovery increases with increasing KAX concentration i.e. the flotation recovery enhanced to 96 %. Also the recoveries and contact angles are much higher compared to KAX and DDA alone are used. The spectroscopic data are interpreted in the light of flotation, zeta potential and contact angle results.

Physicochemical studies of oxide zinc mineral flotation

2016-9-29 · The studies on oxide zinc ore indicate a maximum bench scale flotation recovery of 84.5 % with zinc grade 24.5% in the presence of dodecylamine at pH 11.5. There are no significant variations in recovery of cationic and anionic and mixed collectors, however, amine and mixed collector flotation show to be more selective than anionic collectors.

Lead Zinc Separation by Flotation Froth Flotation

2021-6-5 · The relative galena and sphalerite contents do not change the surface chemistry and tend only to have an impact in cases where the galena content is higher than the sphalerite content, e.g. at Cannington where if the lead feed grade relative to zinc is too high, then too much of the faster floating zinc with lower iron content is recovered to the lead concentrate, making zinc target concentrate grade
