iflotation of metal

Downloaded By: [HEAL- Link Consortium] At: 09:40 18 June 2007 DISSOLVED-AIR FLOTATION OF METAL IONS 1747 stoichiometric amount required. This seems to contradict previous results, where a 30% excess of sodium sulfide was found to be adequate (If), but a possible explanation can be traced to froth flotation (14) where sodium sulfide constitutes a depressing agent for sulfide ores.

    Flotation of metal hydroxide precipitates. I. Flotation of

    Flotation of copper hydroxide precipitate has been investigated at total initial copper concentration 10 −2 M with sodium dodecylbenzenesulphonate (DBSNa) and dodecyldimethylbenzylammonium bromide (DDMBABr), both at initial concentration 10 −4 M. In particular, granulometric analysis of the precipitate and measurement of its electrokinetic potential were carried out over a wide range of ...

    Flotation Mineral Processing amp Metallurgy

    Jan 11, 2016 The FLOTATION PROCESS is one of the commonest methods of extracting the valuable minerals from certain classes of ores, and it is generally more efficient as regards the recovery of the minerals than any other process applicable to the treatment of similar types of ores. The metallic contents of the minerals are recovered from the concentrates in a subsequent series of metallurgical operations—e.g., smelting, refining, etc. —the final product of ingot metal …

    General Principles and Processes of Isolation of Metals

    Native ores contain the metal in the free state. Silver, gold and platinum occur as native ores. Oxidised ores consist of oxides or oxysalts, such as carbonates, phosphates, sulphates and silicates of metals. Sulphurised ores consist of sulphides of metals like iron, lead, zinc and mercury. Halide ores consist of halides of metals.
