Recovery of metal values from copper slag and reuse of ...

Recovery of copper from copper slag by physical beneficiation using froth flotation was studied by Sarrafi et al. (2004). They used mercaptobenzothiazole (MBT) collector to recover the copper from the ground copper slag and indicated that a slow-cooled slag would be more favorable for better copper recovery.


Processing of copper converter slag for metal reclamation ...

Laboratory flotation tests of slow cooled converter slag have showed that 92.5% copper recovery at the copper cut-off grade of 24-25% can be achieved by using a …


PYROMETALLURGICAL RECOVERY OF COPPER VALUES …

A major advantage of pyrometallurgical slag treatment in accordance with the present invention over milling and flotation is that subsequent recovery of molybdenum is possible. The overall process wherein copper and molybdenum is recovered from converter-type slags is shown schematically in FIG. 3.


Copper Recovery Through Smelter Slag Flotation in …

copper grade of 16,11% and copper recovery of 69,90% was achieved. The copper grade on tailings was only 0,2%. Another aspect that can affect both the milling and flotation of CS is the cooling behavior of the slag. Several researchers have reported that slow cooling of the slag can lead to an improvement in copper recovery because of the ...


How to Recover Copper from Slag by Flotation

Recovery of copper in concentrates from slags cooled in the induction furnace and ground for 30 minutes ranged from 87.1 to 96.2 percent with the best recovery obtained on the highest grade slag sample. Copper content of the flotation tailings, which is the most important indicator, ranged from 0.26 to 0.39 percent.

Recovery of Copper from Reverberatory Copper Slag and ...

concentrate, various mining operations have initiated the recovery of copper from dumped slag. The typical process uses crushing, milling and flotation. These operations create excessive liner wear rates during crushing and milling because the bond work index of copper slag is 22 kWh/t and this is considered a very hard slag.


Copper in solidified copper smelter slags

Major part of copper lost in slag is recovered through slag cl eaning operations. Copper losses in slag are of two main t ypes: copper is either dissolved in molten slag as cuprous oxide (or as sul phide) or forming a mechanical dis persion in slag. For slag cleaning by f roth flotation mineralogy and morphology of s olidified slag as well as


REUTILISATION OF PRIMARY METALLURGICAL WASTES: …

Slag flotation This slag cleaning process requires slow cooling, crushing grinding and flotation of smelter slag with copper metal and sulphide particles reporting to the flotation concentrate. This process was widely used in the past by small miners because it is a very simple and effective way to recover copper.


The effect of primary copper slag cooling rate on the ...

Technological procedure of slow cooling slag from primary copper production is applied in the purpose of copper recovery in the level of 98.5% to blister. This technological procedure is divided into two phases, first slow cooling of slag on the air for 24 hours, and then accelerated cooling with water for 48 hours. Within the research following methods were used: calculation of …


THE EFFECT OF COOLING RATE OF SLAG FROM …

The content of copper in the flotation tailings directly depends on fragmentation rate (Figure 1). Expected content of copper in the flotation tailings, in the case of cooling in pits, is 0.5-0.9%, and in the case of cooling in pots, from 0.22 to 0.35% Cu. Fig. 1. The effect of fragmentation rate on the slag flotation [6]


Recovery of Copper from Slow Cooled Ausmelt Furnace …

Ausmelt furnace slag contains about 0.9% Cu (mass %). With increasing the amount of Ausmelt furnace slag, the recovery of copper from it will produce an enormous economic yield. The recovery of copper by floatation from slow cooled Ausmelt furnace slag was studied in this paper. The phases and composition of the slow cooled slag were analyzed.

The recovery of copper, by flotation, from calcium-ferrite ...

Flotation has been identified as the most economical option to recover the copper from direct copper converting slags (Somerville et al., 2000) where it has been estimated that a copper recovery from the slag of above 90% is required to make the overall single-stage copper making process economically feasible.
