3.1 Effect of pH on the Flotation of Converter Slag Converter slag sample was floated at different pHs and the results are given in Fig. 1 [21]. This study was carried out under the conditions indicated in Table 2. As seen in Fig. 1, the best flotation yield was at pH 11.0. For flotation, 100 g of the ore sample was fed and 28.56 g of converter slag was floated. The flotation

Hydrophobic-surface of copper from converter slag in the ...

01/07/2013  The converter slag from a smeltery in Daye contains 2.01% copper. The floatability of copper has a significant influence on the flotation of converter slag. Flotation tests, contact angle tests and FTIR were conducted to assess the influences of pH and different flotation concentrators on its hydrophobic process, mechanism and flotation. The results show that since chemisorptions are formed on the surface, hydrophobicity of copper

All these three furnaces produce fayalite slag as a byproduct. The slags contain copper with the content ranging between 0.8 to 5% copper. The slags cannot be discarded due to the high content of copper and hence they are sent to a milling and flotation plant (Slag Mill Plant) for liberation and recovery of copper. This work focuses on optimizing

The Naoshima Smelter has employed the convert er slag flotation method in order to increase reverberatory smelting capacity instead of returning slag to the reverberatory furnace. As the result, we could point out the following advantages; 1) Copper anode produced from copper concentrate was increased 25%, from 3,000T/M to 3,800T/M.

RECOVERY OF COPPER FROM SMELTING SLAG BY SULPHATION ...

Pyrometallurgical production of copper generates two slags: smelting furnace slag and converter slag which contain 0.5-2% Cu and 2-8% Cu, respectively. The following three methods are generally utilized for recovering the copper from these slags on an industrial scale: (i) recycling of the converter slag to the smelting furnace, (ii) cleaning of smelting and/or converter slags in electric furnaces and (iii) flotation.

PYROMETALLURGICAL RECOVERY OF COPPER VALUES

Since the direct reduction of converter slags separates copper as a high matte grade product (nominally greater than 40 percent copper), it is necessary to provide a pyrite or copper concentrate "wash" to reduce the copper to 0.5 weight percent or less. Thus, pyrite or copper concentrates may be added to reactor 16 through launder 30 (see FIG. 1). The data in FIG. 7 shows that depending upon the silica
