Flotation process : Sulfur makes up a substantial portion of the mineral in the lead ore galena which is called lead sulfide. The flotation process helps in bringing out the sulfurbearing portions of the ore, since it also contains the valuable metal. The finely crushed ore is diluted with water and then poured into a tank. The mixture of water and ground ore together is called slurry to ...

The tails from the froth flotation may then be finely ground and subjected to several additional flotation stages to improve recovery of the precious metals, and the entire operation is preferably carried out as a closed loop process so that only the tailings from the rougher flotation are removed and shipped to the smelter.

Stabilization of lead and Zinc Flotation Circuits
flotation plants resulted in unsaleable lead concentrates being produced due to higher iron deportment to lead concentrates. This was primarily due to the lead circuit only having one stage . cleaning. Figure 5 shows the downward trend in lead recoveries and note that at times of lower head grades during 2001 and 2002, the lead circuit was not

It essentially consists of silicalead slags with very little iron in them and with no magnetite. Furthermore, the grinding and flotation of the dore slag according to the present invention, is intended to improve recovery of precious metals rather than of copper, as in the case of converter slags. In fact, the slimes which are charged into the ...

· Large amounts of lead slag are produced during the production of primary lead and secondary lead. Considering lead concentrate smelting as an example, a primary lead smelting system production of 1 t of lead will discharge 7100 kg of lead slag ().At the secondary lead recycling process, for each ton of metallic lead produced, 100–350 kg of slag are generated (Kreusch et al., 2007).
