A hydrometallurgical process for treating slag material, especially copper smelter slag material, comprises vigorously mixing the slag material with about one part by weight of sulfuric acid and about one part by weight of water for each part by weight of the slag material, and allowing the resulting mixture to react to produce a dry, solid material, containing the metal values of the slag in ...
Copper Slag General Information, Process, Products, Patent ... Recycling copper slag to recover metals has been focused on copper recovery. ... Copper slag is widely used in the sand blasting industry and it has been ... as elution from copper slag; Process for recovery of iron from copper slag ...
Nov 14, 2013· Recovery of value metals from copper smelter slag by ammonium chloride treatment. ... Fig. 7 shows a proposed process flowsheet for the copper, zinc, and iron recovery from copper smelter slag of Balkhash copper plant. In this process, crushed slag, with ammonium chloride in a weight ratio 1:2 is subjected to heat treatment for 120 min at 320 ...
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 – % ...
ISASMELT technology has been applied to lead, copper, and nickel smelting, and by 2013 fifteen plants were in operation in ten countries, with another five in various stages of development. The installed capacity of the operating plants in 2013 was over 8 million tonnes per year (t/y) of feed materials, with additional capacity to come on line in 2013 and 2014.
copper slag recovery through a flotation route. Almost in all of the flotation methods used to recover copper from slags, the Cu recovery was associated with many problems such as high grade of copper in tailing. In the present study, the use of grinding time increased the copper slag recovery a lot.
materials from copper slag. Recovery of copper, molybdenum, precious metals, silica and iron, that is the most abundant component of the slag, are the goals for this research. Metals, commercial compounds, alloys and different forms of iron oxides for steel industry are proposed products.
White Pine reverberatory furnace slags contained economically recoverable amounts of copper for a variety of reasons. Among them: White Pine concentrates yield extremely high matte grades (65+% Cu) and viscous slags. The viscous slags hinder matte settling causing matte "prill" entrapment in the slag. White Pine''s total refined copper output is accomplished through fire refining ...
Minerals 2016, 6, 119 2 of 11 settled in the slag cannot be effectively utilized. Main methods in use for iron recovery from copper slag include direct beneficiation for iron recovery [3], oxidative modification [4,5] of iron oxide for iron
Breakthrough has been made to combine the process of brass scrap and low grade copper scrap. By metal distillation technology, our clients can extract not only copper but also high purity zinc and high purity lead. Customertailored Top Blown Rotary Converter (TBRC) makes the process more flexible to copper scrap recycling of different capacity.
Copper smelting slag is the solid waste generated in the process of smelting copper. Due to the limitations of the smelting technology, most of the copper smelting slag contains a certain amount of copper. Disposing and recycling copper can effectively reduce the waste of useful resources, while generating considerable economic effectiveness.
Effect of CaO Addition on Iron Recovery from Copper Smelting Slags by Solid Carbon JUNG HO HEO, BYUNGSU KIM, and JOO HYUN PARK We investigated the effect of flux (lime) addition on the ...

COPPER SLAG . Copper slag is the most economical expendable abrasive for blasting purpose in areas where recovery and recycling is impractical. It is a byproduct formed during the manufacture of copper while smelting and quenching process in copper smelter. The raw slag is processed and screed in various grades for blasting purpose.
EBSCOhost serves thousands of libraries with premium essays, articles and other content including Recovery of Copper and Silver by Flotation from Smelting Copper Slags. Get access to over 12 million other articles!
Copper slag is a byproduct obtained during smelting and refining of copper ore rich in sulphides and oxides of iron and copper, in the course of removing iron as iron silicate. During the smelting process at 1250°C, copper liquid settles down due to higher density while copper slag remain on the surface in the segregated state.
Recovery of copper from copper slag and copper slag flotation tailings 77by oxidative leaching Leaching with ferric sulphate The slag and the slag flotation tailings were leached with ferric sulphate in 1 M sulphuric acid. The ferric iron concentration was varied in the range from 5 g/dm3 to
Technological procedure of slow cooling slag from primary copper production is applied in the purpose of copper recovery in the level of % to blister. This technological procedure is divided into two phases, first slow cooling of slag on the air for 24 hours, and .
Recovery of Copper and Cobalt from Copper Slags as Selective 389 intervals. By treatment with hot water, recovery of copper and cobalt from the ore mixture was aimed selectively. 2.
