Sebastián Porras, -18 Slag Flotation Cells of 30m3 for Codelco Chuquicamata-6 Copper Flotation Cells of, Project Engineer in Flotation Cells, During this period I've worked with its respective Project Manager in the coordination of engineer, procurement and management of the following Projects:-34 Copper Flotation Cells of 300m3 for Sierra Gorda SCM;Recovery of Copper from Reverberatory Copper Slag and ,, possible option The copper slag contains a high content of silica and iron The solution final pH is the most important factor affecting the removal of iron and silica from the leach solution and the overall metal recovery Fe removal from the leaching of copper slag is done by the formation of a metal hydroxidecopper slag flotation plant, Copper Slag Flotation Chuquicamata Codelco - Wikipedia the free encyclopedia Copper has been mined for centuries at Chuquicamata as was shown by the However their gradual depletion forced the construction of a mill and flotation plant smelter and one Teniente converter with electric furnace and cylindrical slag,PAPER OPEN ACCESS Research on the Process of Sulphatizing ,, the simultaneous accumulation of waste induce to process generated and dump slag of copper smelting Such slag contains 05-2% Cu  To extract copper from slag wastes, froth flotation method is frequently used [3, 4] due to its relatively low cost Flotation process also forms tailings with higher contents of zinc and copper than in natural ,Effect of Cooling Rate and Slag Modification on the Copper ,, copper sulfide particles was promoted, and thereby the parti-cles could be better collected in the subsequent flotation to reduce copper losses in the waste slag In addition to testing the cooling time and controlling the cooling rate, some researchers have even considered using slag modification to increase copper recovery Wang .
US4022686A, 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 ,(PDF) PHYSICOCHEMICAL CHARACTERIZATION OF COPPER SLAG ,, The copper content of the slag recovery [21, 22] decreases rapidly while iron content remains almost Figure 7 shows the different associations between constant during this period of time, indicating a copper, iron, silica and molybdenum into slag  selective reduction of copper giving a final slag and we can appreciate that, as established ,UG, Copper Slag Gradation: Reverberatory copper slag can be processed into coarse or fine aggregate material for use in embankment applications Copper slag can readily satisfy the gradation and physical requirements of AASHTO M145 (11) Unit Weight: Copper slag has a unit weight of 2800 to 3800 kg/m 3 (175 to 237 lb/ft 3)chuquicamata copper mine chile, Oct 24 2017 The concentrator contains a separate circuit for recovery of copper from the on-site smelter slag Slag can contain between 8 and 10 Cu and is sent to its own process line containing a SAG mill two ball mills and floatation circuit The Chuquicamata mine s smelting process involves two stages a smelting stage and a conversion stageThe Recovery of Copper from Smelting Slag by 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 copper-bearing mineral after a detailed mineralogy analysis via ,.
Impacts Of Slag Mill And Flotation, Production of copper concentrate by flotation of smelter slag has started in 2001 Flotation concentrate goes to the Copepr Smelter once more for production of cop-per cathodes and the rough flotation tailings go to the flotation tailing dump Copper recoveries in the flotation process of smelter slag reaches the value of about 45- 50%2, 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 ,
