The Jameson flotation cell is installed in many mines around Australia. Ground ore, water and special chemicals are mixed and constantly agitated in banks of flotation cells. Air is blown through the mixture in each cell, and the fine zinc sulphide particles stick to the bubbles which rise to form a froth on the surface of the flotation cell.

Today, about 400 million tonnes of sulphide ore is treated annually by flotation process worldwide. M/s Hindustan Zinc Ltd. (HZL), a leading lead-zinc mining and smelting company in India has experienced a spectacular growth from the time of its inception. Starting from a single 500 MT per day lead-zinc mine at Zawar, HZL has expanded its …

One merit of this new process technology is that the zinc sulfides and oxides can be recovered without desliming in the flotation cells at the different stage and make sure the concentrate products as a good feed for hydrometallurgical technology. ... Mining & Metallurgy. 2012: 21(1): 4-7. 8. Zhang X, Shao G, Wu P, Bai X. Study on the flotation ...

Pneumatic flotation cells also have been used to remove carbon particles from fly ash used as raw material for cement and mortar (Imhof, 1986). However, to date the cells have been primarily used to float nonmetallic ores (for example, coal, apatite, magnesite, fluorite and so on). Pneumatic flotation of lead-zinc ore was also tested, but

The flotation process and related flotation cells are widely used for treating metallic and nonmetallic ores and in addition, it is receiving an ever widening application in other industries. A greater tonnage of ore is treated by flotation than by any other single process. ... "Sub-A" Cells are required to treat 125 tons of lead-zinc ore ...

Flotation of these sulfide ores is accomplished using multi-stage differential flotation. Several flotation cells are used to separate and recover galena (lead sulfide, PbS), followed by floating sphalerite (ZnS) in a sequential manner (Basilio et al., 1996). ... kinetic studies for the lead-zinc sulfide ore flotation have reported that the ...

Conclusions. Cyanide has been used to improve the selectivity in the flotation of base metal sulphide minerals. Iron, copper and zinc sulphides can be depressed by free cyanide when xanthate is used as collector. The mechanisms underlying the depression effect on pyrite flotation may be attributed to the formation of insoluble hydrophilic iron ...
