Extraction of Zinc: Process, Ores, Diagram
Metallurgy of Zinc. The principal ore of zinc used for its extraction is Zinc blend (ZnS) ( Z n S). As Zinc blend is a sulphide ore, the process used for its concentration is the Froth Floatation Method. The concentrated ore is then roasted in excess air at 1200K 1200 K to obtain zinc oxide (ZnO) ( Z n O). It is then reduced to Zn Z n by coke ...

Roasting Galena Concentrate with Lime
The ore was a galena-concentrate from the Coeur d'Alene district, Idaho. A screen-analysis gave the data presented in Table I., which shows that, with the exception of two grades, the 9- on 12-mesh and the through 100-mesh, the different sizes were evenly distributed. The ore was crushed to pass a 2.8-mm. screen.

Lead Ore
The oxide lead ore in a dolomitic matrix may contain clay slimes and a fairly large amount of pyrite and barite; both of these minerals have a negative effect on oxide lead flotation. These ores may contain one or several lead minerals, including cerussite, anglesite and pyromorphite. Some lead oxide ore varieties may contain oxide copper ...

Lead (Galena) Facts
The most common ore mineral of lead mined in the United States is galena with the chemical symbol PbS. Galena is lead sulfide with a hardness of 2.5 on the Moh's scale - actually quite soft- but it is VERY heavy with a specific gravity of 7.4 to 7.6. To put that in perspective, it weighs about 700 pounds per cubic foot!

Galena
Galena is the primary ore mineral of lead. Worked for its lead content as early as 3000 BC, it is found in ore veins with sphalerite, pyrite, chalcopyrite, tennantite-tetrahedrite, etc. and in skarns, as well as in sedimentary rocks where it may replace carbonate beds or be deposited in pore spaces. The crystals are bright when fresh but often ...

Galena Processing Plant, Gravity Separator of Galena, galena ore
The gravity separation separator commonly used for beneficiation of galena is a jig machine. For the coarse-grained galena, we can use the AM30 jig machine, and the selected size of this jig machine can reach 30mm. For that fine-grained galena, we can use the 2LTC-6109/8T jig machine. This jig machine is aimed at 0-8mm fine minerals.

Galena is the ore from which elemental lead is extracted. In the first step of the extraction process, galena is heated in air to form lead (II) oxide. 2PbS ( s) + 3O 2 ( g) → 2PbO ( s) + 2SO 2 ( g) Δ H = –827.4 kJ. What amount of heat (in kJ) is liberated if 224 g of Galena (PbS) is converted to lead oxide?

Pyrometallurgy: Roasting, Smelting, Refining & Electrowinning
The ore is composed mainly of arsenopyrite, pyrite, galena, and polybasite. There is minor barite present as well. The ore was crushed to 150 micron and calcined using a two stage process, 90 minutes at 900F in a reducing atmosphere (to reduce arsnic), and again for 4 hours at 900f in an oxidizing atmosphere to drive off sulfur.
