The recommended technological parameters for leaching of copper (the most important component) from converter slag flotation tailings are: pulp density of 30% (w/v), pH, temperature of 70 #176;C
A flotation process in which copper ores or copper converter slags are ground and firstly have added thereto benzotriazole or alkyl benzotriazole as an activator and secondly one or more collectors selected from the group consisting of xanthates, dithiophosphates, thiocarbamate esters, dithiocarbamates, mercaptans and dixanthogens and further, if desired, a promoter such as kerosene, light oil
The recommended technological parameters for leaching of copper (the most important component) from converter slag flotation tailings are: pulp density of 30% (w/v), pH, temperature of 70 #176;C
#0183;#32;The slags produced from the NCS furnaces (TSL furnace, copper converter, reverberatory furnace) contain copper ranging between to 5% w/w. Due to this high content of copper, the slags are milled and floated to recover the copper. The main drawback in the current process is that the final flotation tailings grades are in excess of % Cu.
#0183;#32;The recommended technological parameters for leaching of copper (the most important component) from converter slag flotation tailings are: pulp density of 30% (w/v), pH, temperature of 70 #176;C, initial Fe 3 + concentration of g/L, no aeration, leaching for h.
Pyrometallurgical production of copper generates two slags smelting furnace slag and converter slag which contain cu and 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,
Converter slag crushing magnetic solutions copper flotation from converter slags 25, 2016 slag crusher machine for iron,copper,lead is used for crushing slag in the slag a study of the optimal model of the flotation kinetics of archives of mining sciences in this study the effect of.
Abstract. Aiming at the recovery of copper from smelting slag, a flotation approach was studied. It was found that this slag composed of fine particles with complex association and distribution, in which bornite was the main copperbearing mineral after a detailed mineralogy analysis via
Copper Flotation From Converter Slags. 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 andor converter slags in electric furnaces and iii copper and sulphide copper present in these slags can be floated very.
As seen in Fig. 1, the best flotation yield was at pH For flotation, 100 g of the ore sample was fed and g of converter slag was floated. The flotation yields of Cu and Co were determined as % and Recovery of Copper and Cobalt from Converter Slag with a New Flotation Method Using H2S
Key words: Converter slag, flotation, copper, cobalt, sulphurization. 1. Introduction Copper slag is produced in large amounts in seven copper smelter plants in Chile, and it is estimated that around 4 million tons of slag are disposed every year and another 40 to
gt; Copper Flotation From Converter Slags Feb 15 2007 This study was designed to recover copper and cobalt hydrometallurgically from an enriched concentrate of flotation and converter slag Three slag samples collected from the Ergani Copper Co of Etibank were studied In order to convert the copper and cobalt into sulfate compounds samples were roasted after sulfurization and leached with water
Recovery Of Copper From Converter Slags By Flotation. Laboratory batch flotation tests were conducted on copper converter slags to evaluate the relative merits of recovering copper from slow cooled versus waterquenched slags three slags containing 16 50 and 66 percent copper were used more than 90 percent of the copper was recovered in a .
Total copper flotation recoveries before and after regrinding of the tailings using FC7245. note that copper in the converter and TSL slags is generally much higher.
The converter slag from a smeltery in Daye contains % floatability of copper has a significant influence on the flotation of converter slag. Read more OCCURRENCE AND SPECIATION OF COPPER IN SLAGS
A flotation process in which copper ores or copper converter slags are ground and firstly have added thereto benzotriazole or alkyl benzotriazole as an activator and secondly one or more collectors...
copper converter slag, such as resmelting or flotation, are effective for recovering the copper only (Biswas amp; Davenport 1994). The cobalt in converter slag, however, remains in resmelting slag or flotation tailings, and eventually gets lost with their disposal.
