reverberatory furnace in the copper conditions which lead to maximum recovery of an element into the copper during the flotation through a layer of slag. crusher is used in
#0183;#32;The optimum condition for flotation of the reverberatory furnace slag at Sarcheshmeh Copper Complex is as follows : pH=; R407=30 g/t; solid in pulp=30%; flotation time= min; MIBC=35 g/t. Slow cooling of the molten slag (in the range of #176;C) increases the copper recovery considerably (about 85%), and can also reduce the comminution time to less than 30 min.
#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.
The recovery of copper and cobalt from ancient copper slags from the K#252;re region of Turkey was investigated. A fayalitictype of ancient copper slag containing % Cu, % Co and % Fe were subjected to an experimental study. Two different routes were followed to recover the metal values. The first route was roasting the slag with pyrite followed by leaching.
Recovery of copper from reverberatory furnace slag recovery of copper from reverberatory furnace slag by flotation prompt caesar is a famous mining equipment manufacturer wellknown both at home and abroad, major in producing stone crushing equipment, mineral separation equipment, limestone grinding equipment, etc
For an aircooled slag at optimized conditions, 72% of copper was recovered in one stage flotation and a % copper concentrate was achieved. The best recovery efficiency was obtained when 30 g...
The reverberatory furnace slag that has been dumped in the vicinity of the Bor Copper Smelter, Serbia, is currently processed by flotation using an existing production line at the nearby Bor Copper Concentrator. However, the copper recovery 74 Urosevic, Dimitrijevic, Jankovic, Antic
The recovery of copper from reverberatory furnace slag utilizing flotation has been studied. The effective factors such as particle size, pH, the amount and type of collector and additives, and...
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 recovery of copper minerals in copper smelter slags by means of froth flotation.
Enhancing the flotation recovery of copper minerals in smelter slags from Namibia prior to disposal. process a range of copper concentrates in their three furnaces, namely; top submerged lance, copper converter and reverberatory furnaces, the slags are sent to a milling and flotation plant for liberation and recovery of residual copper.
Reverbetory furnace slag Copper recovery Flotation Milling and grinding ABSTRACT Namibia Custom Smelters (NCS) process a range of copper concentrates in their three furnaces, namely; top submerged lance, copper converter and reverberatory furnaces, in order to produce mattes and fayalitic slags. The
The recovery of copper from smeltery furnace slag by flotation has been studied. By analysis the slag containing % copper and /t silver is available to recovery. The effective factors such as particle size, the amount and type of collector were examined. The combination of the collectors was also examined. With the process utilized in this work, a copper concentrate of % Cu with
flotation tests which were performed on slag samples from three different sources (TSL furnace, copper converters, reverberatory furnace) to recover the copper minerals. A range of commercial flotation reagents including xanthates, dithiophosphates, mercaptobenzothiazole,
copper slag flotation machine . Recover Copper from Reverberatory Furnace Slag Laboratory and pilot plant investigations have indicated that copper recoveries of 50 can be achieved with fine grinding and flotation of a copper reverberatory furnace slag Microscopic and microprobe studies indicate that the recoverable copper is in the form of matte chalcocite and metallic copper the percentage
Recently smelter copper slags stockpiled in dumps are being reprocessed by crushing, milling and flotation to recover entrained copper contents. This technique produces a flotation concentrate copper grade of approximately 25 to 30% with copper recoveries of between 60 and 70%.
Laboratory and pilot plant investigations have indicated that copper recoveries of 50% can be achieved with fine grinding and flotation of a copper reverberatory furnace slag. Microscopic and microprobe studies indicate that the recoverable copper is in the form of matte, chalcocite, and metallic copper; the percentage of copper in particles appearing to be copperfree was from %
Recovery of Copper from Reverberatory Copper Slag Slags are waste minerals produced during furnace smelting of minerals. because copper slag has a bond work index of 22 kWh/t and is thus a very hard slag. The process also has reduced flotation recoveries and requires high flotation
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
