1. Introduction. Copper and lead are common and important metals that are widely used in many fields of production and human life. At present, sulfide ore resources are still the main source of copper and lead metal, and the sulfide ore of copper and lead usually refers to chalcopyrite (CuFeS 2) and galena (PbS) [1].Flotation has the …

A bulk rougher flotation of copper and lead followed by a reverse separation to float copper and depress lead. A sequential copper-lead-zinc flotation process. A process to produce higher grade copper concentrates by depression of lead.

This paper reviews uses of sodium sulfide in the flotation of oxide minerals of copper, lead, and zinc. The activation and depression effects of sodium sulfide are of particular importance because of their applications with oxidized lead and copper ores. In spite of its industrial importance, the nature of the heterogeneous reactions between …

15.1.1 Hydrothermal Vein Deposits. The copper lead-zinc vein deposits are usually characterized by coarse-grained banded to massive aggregates of pyrite, galena, sphalerite and chalcopyrite. The bulk mineralogy is quite similar to that of strata-bound sulfide deposits, except that galena tends to be much more abundant in the vein deposit.

indicators were acquired. On the basis of process mineralogy, according to the process "bulk flotation of copper and lead - separation of copper and lead - zinc flotation from tailings", a flotation test to a polymetallic ore was carrried out[5]. The final products with the recovery of 73.21% Cu, 84.47% Pb

Froth flotation is a very important mineral concentration process that is used to recover a vast array of different minerals containing valuable commodities such as copper, lead, zinc, nickel, molybdenum, tungsten, silver, gold, phosphate and potash.

The closed-circuit flotation test of copper/lead bulk concentrate shows that the grade and recovery of Cu reach 30.47% and 89.16% respectively and those of Pb reach 2.06% and1.58% respectively in ...

Who would think that Selective Flotation of copper, gold, zinc or any metal would required that one must be able to feel pain and recognized and/or admit when it hurts. Flotation mass-pull is a process that is often misunderstood; a learner's mistake made by non-operating types.. You do not need to pump anything in the lab.. In selective …

Example of a sequential Cu-Pb-Zn flotation flowsheet. Copper is concentrated first, at lower pH, followed by lead and, finally Zn. Adapted from Bulatovic (2007b).

The bulk copper–lead flotation with depression of zinc followed by copper–lead separation and re-flotation of zinc is the most common practice in the treatment of copper–lead–zinc ores. About 90% of operating plants use this method. The bulk concentrate is usually contaminated with pyrite and zinc.

1. Introduction. Chalcopyrite (CuFeS 2) and galena (PbS) are important raw materials for smelting copper and lead, which mostly originate from polymetallic sulfide deposits [1], [2].Because of the low grade of value metal in primary ore, flotation is required to enrich the desired minerals to obtain concentrates that meet the smelting standards.

The proper combination of reagents causes the selective flotation of zinc sulfides, lead sulfides, and copper sulfides, and rejects the iron sulfides and rock to tailings. The metal concentrates are dewatered, dried, and shipped to metallurgical plants, with each sulfide being sent to the appropriate smelter; the water is recycled to the mill.
