Copper recovery from copper slags through flotation enhanced
Jun 01, 2022Copper recovery can be increased by optimizing the flotation reagent. It is found that the synergistic effect of multiple collectors [38] and Cu 2+ in the pulp [39] can improve the flotation effect. Bruckard [40] carried out flotation recovery tests on different copper slags, and the total copper recovery rate was from 80% to 87%.

Ultrasound treatment on tailings to enhance copper flotation recovery
Dec 01, 2016From Figures can be observed that after twelve minutes of flotation each condition SF, UC, UF, and FCU reaches 27.89%, 28.94%, 29.23% and 31.40% recovery respectively. Therefore, the application of ultrasound equals or exceeds the results obtained by standard flotation without ultrasound. Download : Download full-size image Fig. 6.

Evaluating Copper Rougher-Scavenger Flotation Circuit Grade/Recovery
Nov 04, 2015The recovery of liberated grains of chalcopyrite follows a typical pattern where about 75% of the liberated chalcopyrite is recovered into the rougher concentrate. The copper scavenger circuit essentially recovers the remainder of the liberated chalcopyrite. Liberated grains of galena are about 15% covered into the copper rougher concentrate.

Recovery of pyrite from copper tailings by flotation ScienceDirect
Sep 01, 2019The recovery of pyrite at 5 min of flotation is 97.8%, and at 7 min of flotation the maximum estimated recovery of 99.1% is reached. In order to produce a concentrate with a pyrite grade closest to 90%, and a recovery above 90%, 3.5 min were selected for the recleaner flotation stage as the optimum flotation time. 3.3.

How to maximize ore and grade recovery through flotation
Mar 06, 2020Optimal mineral recovery in a flotation circuit depends on the capacity to adapt to metallurgical variability in the ore being processed. It is possible that some banks of flotation cells might not be recovering ore at their maximum levels due to air flow, feed, mechanical, hydraulic, reagent imbalances.
