Abstract This stone 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
However, lead oxide minerals are selected as potential resources for the lead extraction due to the depletion of lead sulfide ores [4,5] Cerussite, is a typical lead oxide mineral and flotation is a widely used method for its beneficiation However, cerussite does not respond well to traditional sulfide mineral collectors (eg, xanthates
The main difference in lead/zinc flotation is that zinc is usually depressed while lead (and copper) is floated The tailing from the lead flotation circuit is the feed to the zinc circuit The ability to selectively float the separate minerals depends on the ore, the chemicals, and other factors Conclusion Gold, silver, copper, lead, zinc, molybdenum, iron, potash, phosphate, and even sand
1 1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a
Lead(II) sulfate is prepared by treating lead oxide, hydroxide or carbonate with warm sulfuric acid, or by treating a soluble lead salt with sulfuric acid Alternatively, it can be produced by the interaction of solutions of lead nitrate and sodium sulfate Toxicology Lead sulfate is toxic by inhalation, ingestion and skin contact It is a cumulative poison, and repeated exposure may lead to
Flotation 3 The principal lead ore, galena, is properly known as lead sulfide, and sulfur makes up a substantial portion of the mineral The flotation process collects the sulfur-bearing portions of the ore, which also contains the valuable metal First, the finely crushed ore is diluted with water and then poured into a tank called a flotation
Sulphidization flotation for recovery of lead and zinc from oxide-sulfide ores Article in Transactions of Nonferrous Metals Society of China 15(5):1138-1144 · October 2005 with 83 Reads
Infrared reference spectra are presented of compounds of importance in lead sulfide flotation research Included are the spectra of several short chain alkyl xanthates of lead and zinc, the corresponding dixanthogen compounds, and the common oxidation products of lead sulfide and their sodium analogs
Sulfide and non-sulfide minerals as well as native metals are recovered by froth flotation This process is based on the ability of certain chemicals to modify the surface properties of the mineral(s) Other chemicals are used to generate the froth and still others are used to adjust the pH The main difference in lead/zinc flotation is
The lead ore concentrate from the flotation tanks now contains about 50% lead and ca 01% of silver, a relatively small but valuable amount (b) Smelting Smelting is usually a two-stage process as described here, although single-stage methods with lower energy use and emissions are also used
13/08/1996 · Therefore there is a great need for developing less toxic substances to be used in the processing of lead Many techniques for froth flotation of lead sulfide materials are well known in the art Froth floatation renders the surface of the mineral to be collected hydrophobic and hence floatable
