Results of lab-scale tests show that the original high alkaline and desliming process can be replaced by the new process of low alkaline and non-desliming process, and the satisfactory experimental indexes was achieved. 43.37% Pb and 66.01% Ag were recovered by the flotation of lead sulfide ore, and the average grades of Pb, Zn and Ag in Pb ...
About Pb-Cu. Lead and zinc are extremely close in nature, especially in primary deposits, and often coexist. Most of the lead-zinc minerals are sulfides and sulfates, and galena and sphalerite are the primary Pb-Zn ores. Non-sulfide: It is formed due to hypogene and supergene weathering. Mostly oxide ores like zincite, and cerussite may fall under this category.
There are many flotation plants in the world treating Cu-Zn sulfide ores with different flotation conditions and producing copper and zinc concentrates. The nature of Cu-Zn sulfide ores, i.e., ore genesis, grade, mineralogy, surface conditions of the sulfide minerals, determines the flotation conditions and the flowsheet.
The results demonstrate that the ore consists of 35 categories of minerals, assaying Cu 7.99%, Pb 9.39%, and Zn 1.96% in the forms of chalcopyrite, galena, and sphalerite, respectively, and silver ...

Flotation tests. A Cu-Pb-Zn sulfide ore from Somincor (Neves Corvo, Portugal) with a chemical composition of 0.5% Cu, 1.2% Pb, 7% Zn, 32% Fe and 43% S was used. The ore sample is a massive sulfide ore containing chalcopyrite, galena, sphalerite and pyrite as the major sulfide minerals.
Float Metals One-by-One Selectively: Since our objective is to sequentially float Copper, then Lead, than Zinc while rejecting Pyrite, let us explore how we can separate Cu/Pb/Zn from Fe: pH 6-6.5 is where Pb/Zn/Fe are least hydrophobic while Cu is most hydrophobic. Great pH to Recover Cu. pH 7.5-8 is where Zn/Fe are least hydrophobic while Pb ...

Flotation tests on Rockliden composite samples have shown that the threshold of 0.2 wt% Sb is exceeded in the Cu–Pb concentrate even if the Sb grade of the blended feed material is below this value (Bolin, 2010, Minz, 2013).This is related not only to the flotation behaviour of common Sb minerals but also to the mineral association and the degree of …
Chitosan was exploited as a selective depressant in the differential Pb Zn sulfide flotation at pH 4 on artificial galena and sphalerite mixtures. The mixtures were prepared in two different approaches. In the first approach, the high purity galena and sphalerite were blended directly whereas in the second approach, the sphalerite was coated with copper before …

For example, 60 g/t Ag, 0.05% Cu, 0.8% Pb, and 0.7% Zn. In this case, it would be possible to produce a lead concentrate and most of the silver and copper should be reported in the lead …
Flotation outcomes also indicated that NB flotation step up could lead to the highest Pb and Cu recovery and grade compared to the other tested conditions (Figure 1). In other words, the NB assisted flotation (without a frother for the …
Flow sheet: Pb Flotation 1st stage- 2nd stage Zinc flotation. Copper NIL. YOUR CASE: NOW DISCUSSED: Pb, Zn, Cu-Possible flow sheet advised. Bulk flotation of Pb,Cu. Then use MGS to remove graphitic Carbon. Then depress Copper using Dicromite. Yes it is very difficult process. Lot of R&D in Lab, Pilot plant is required.
Flotation with NBs, generated in the presence of a frother, could be considered for the Pb-Cu rougher stage where can lead to a higher mass recovery and Zn selectivity index. In comparison, NB flotation might be used in the cleaner stage to improve the Pb-Cu selectivity index.

ABSTRACT. Problems arising during flotation of complex Cu-Pb-Zn sulphide ores are in general of geological origin. The features of these ores are reviewed, stressing that mineralogical studies extending to process mineralogy are prerequisite for a consistent flotation process. Some examples affecting flotation are given.
for zinc recovery. The Pb grade in the lead rougher concentrate is 2.83%, and the Pb recovery is 57.56%. The Zn grade reaches 28.64% with a recovery of 83.45%. Thus, the findings provide im-portant technical supports for the processing of similar ores. Keywords: low-grade oxidized lead and zinc ore; process mineralogy; selective flotation; all-open
