A sulfidization flotation method has been used on a laboratory scale to investigate the effect of various reagents such as sodium sulfide as sulfidizing agent primary amine as collector
The flotation of smithsonite from tailing which comes from the cerussite flotation circuit was investigated using Armac C and Armac T as amine collectors The results indicated that the dosage of sodium sulfide collector type and desliming are the main affecting factors on the Zn grade and recovery of smithsonite flotation concentrate

29 ensp 0183 ensp The studies on oxide zinc ore indicate a maximum bench scale flotation recovery of 84 5 with zinc grade 24 5 in the presence of dodecylamine at pH 11 5 There are no significant variations in recovery of cationic and anionic and mixed collectors however amine and mixed collector flotation show to be more selective than anionic collectors
The pre treatment of zinc oxide bearing ores with high slime content is important to ensure that resources are utilized optimally This paper reports an improved process using hydrocyclone de sliming dispersion reagents and magnetic removal of iron minerals for the pre treatment of zinc oxide ore with a high slime and iron content and the benefits compared to traditional technologies are shown

When the oxidized zinc ore is floated with an amine collector it is difficult to separate the gangue minerals mainly composed of zinc oxide and calcium magnesium carbonate At the same time the presence of ore slime also affects the flotation using amine collectors

The role of sodium sulphide in amine flotation of the silicate zinc minerals willemite and hemimorphite is discussed Data from the literature are compared with experimental results obtained by the authors in Hallimond tube floatability tests
We have found that oxidized zinc ores in general and the oxidized zinc bearing tailing resulting from flotation concentration of the lead present in mixed lead zinc oxidized ores in particular may be concentrated by flotation in the presence of a soluble sulphide and a soluble compound of an aliphatic amine containing from 8 to 18 carbon atoms
Abstract Smithsonite a typical zinc oxide mineral has been developed for many years as an alternative source However restricted to inferior ability of floating zinc oxide is one well known refractory mineral with poor selectivity and high regent consumption
