Similar to the copper circuit, the grade and recovery of copper and zinc to the leadFLOTATION OF OXIDIZED COMPLEX COPPER-LEAD- ZINC ORES,Copper recovery at the rougher stage was 67.39 %. After three stages of cleaning, grade of the concentrate was increased to 31.38 % Cu. Similarly, lead recovery at the rougher stage was 34.72 %. After three stages of cleaning, grade of the concentrate was increased to 51.32 % Pb and finally zinc recovery at the rougher stage was 51.88 %. After two stages ofDE-ZINCING OF LEAD-COPPER SULPHIDE MINERALS FLOTATION,recovery of lead and copper at PbCu-rougher stage is found low at about 72 and 49% respectively, while the zinc component is highly distributed (57.8%). Consequently, the recovery of zinc at rougher sphalerite flotation is poor (36%). This phenomenon indicates that sphalerite does not effectively depressed yet by ZnSO4.

Overall 15% of the liberated grains of sphalerite are recovered in the combined rougher
How to Process Low-Grade Lead Zinc Ore by Flotation
27/04/2016· The flowsheet above was designed to treat economically approximately 200 tons in 24 hours of a low-grade dump ore containing lead and zinc values as well as some silver in both sulphide and oxide form. Due to varying specific gravities of the values, gravity concentration in addition to flotation was indicated. As is common in many such cases, the dump contained material over 2″ inLead-Bismuth Flotation - 911 Metallurgist,28/02/2016· However, bismuth is seldom present in the deposits of a copper-chloride vein type or in a copper-lead-zinc vein type. Porphyry type deposits can have present bismuth. When bismuth is present as a solid solution in the sulphide minerals, it is concentrated in the final products such as copper, lead, and zinc concentrates.

The identification tests showed that the sample is a mixture of quartz, chalcopyrite, galena, cerussite, hemimorphite and iron oxide minerals with 5.04% CuO, 1.61% PbO, 2.07% ZnO and 56.40% SiO2. The experimental design methodology (RSM) was conducted to investigate the effect of,Copper-Lead-Zinc ores - Danafloat,The zinc reporting to the bulk flotation tails feeds the zinc circuit which is operated as previously described in the lead-zinc flotation section. Which flotation scheme used in the differential copper-lead bulk concentrate separation is generally and often dependent upon which mineral has the greater mass in the bulk concentrate. Whichever,
Effects of Process Parameters on Selective Flotation of,
flotation is widely used for concentration of low grade lead-zinc ores for meeting the required specifications of the concentrates for extraction of metals (Wills 1988). The recovery of lead and zinc bearing minerals as well as the selectivity of separation are greatly influenced by the mineralogical characteristics of the ore and the various process parameters.
