Equipment For Recovering Copper From Furnace Slags

slags from some smelting furnaces are higher in copper content than the original ores taken from the mines. Therefore they may be sent to a concentrator for copper recovery. Tailings from flotation of copper slag are a second RCRA special waste. Traditionally reverberatory furnaces have been the most common furnaces used

Apr 13 2011 Monitor the temperature inside the furnace closely and allow it to continue to heat up until the temperature inside of the furnace is approximately 1200 degrees C or about 2192 degrees F. Step 2 - Create the Slag. The slag is the liquid metal mixture that will be the result of the temperature being raised to the high level that it is. To .

The copper content of the slag is maintained at 0.5 to 0.6 percent Cu by maintaining a reducing atmosphere in the slag cleaning furnace. The slag then flows by gravity to the converter furnace. The converter furnace produces anode copper which flows to a holding furnace prior to anode casting. Slag from the con- verter furnace is granulated .

includes 1 recovery of copper metal from edge trim of printed circuit boards 2 recovery of tin metal from tinlead solder dross in the hot air leveling process 3 recovery of copper oxide from wastewater treatment sludge 4 recovery of copper from basic etching solution 5 recovery of copper

Oxygen-enriched air is also employed for reaction with the copper concentrate. Matte and slag are formed with the addition of fluxes to aid separation and to minimize copper solubility in the slag which is later treated for copper recovery Table I 6. The flue gas from the flash furnace is typically processed in a sulfuric acid plant.

Jun 18 2014 The slag valve was installed and commissioned in 20112012 on a 12 MW furnace as part of a new mineral wool plant built in the USA. Although the design intent was for

Responsible for the demolition of a 75 MW FeNi furnace and engineering review from the operational point of view commissioning and startup of a new line to carry the furnace at 95 MW and improvement in various areas such as Up grading of ore systems gas cleaning systems slag

At the Inspira- tion plant slag is poured off and transferred in ladles via the EOT crane and charged into the electric smelting furnace for recovery of the copper. As with the Peirce-Smith converter the slag blow is fol- lowed by the blister copper blow.

Slag of aluminum is a residue which results during the melting process of primary and secondary aluminum production. Salt slag of aluminum is hazardous solid waste according to the European Catalogue for Hazardous Wastes. Hence recovery of aluminum not only saves the environment but also has advantages of financial and economic

the concentrates has been designed to maximise lead recovery to fume and cobalt recovery to matte. The Ausmelt plant will produce 78930 tonnes of cobalt-copper-nickel-iron matte 115140 tonnes of discard slag and 103480 tonnes of high lead fume per annum. The overall design and costing study managed by Hatch encompasses all plant unit

Step 2 - Create the Slag. The slag is the liquid metal mixture that will be the result of the temperature being raised to the high level that it is. To .

Slag from the cupola furnace was being produced at a rate of approximately 8000 pounds per day. Quinn sought to reduce the slag production and in turn reduce thier volume of waste. They first attempted to locate a metal recovery operation for the slag. However metal recovery did not prove economical for the facility.

Apr 30 2015 Larger furnaces are suited to foundries specialising in the smelting of drosses and similar materials. Monometers copper refining rotary furnaces offer the highest possible purity refining of any fire refining technology achieving up to 99.9 purity from scraps such as BirchCliff. Cycle times are typically under 5 hours for a 5 tonne charge.

Waste Heat Reduction and Recovery for Improving Furnace Efficiency Productivity and Emissions Performance high-temperature furnace can attest to the huge amount of thermal energy beamed into the room. Anywhere or anytime there is an opening in the furnace enclosure heat is

Copper processing - Copper processing - Roasting smelting and converting Once a concentrate has been produced containing copper and other metals of value such as gold and silver the next step is to remove impurity elements. In older processes the concentrate containing between 5 and 10 percent water is first roasted in a cylindrical refractory-lined furnace of either the hearth or .

May 25 2017 The main component of the equipment is an electric tube furnace. A crucible with copper slag was placed in the furnace tube and the top of the furnace tube was sealed using a
