iron sulfide. Because copper has a higher affinity for sulfur than oxygen, the copper in the slag (as copper oxide) is converted to copper sulfide. The copper sulfide is removed and the remaining slag is discarded. Converting produces blister copper by eliminating the remaining iron and sulfur present in the matte.
Sales Inquiry Copper Slag Used For Cement Waste as meaningful substitute for natural sand . Holcim Singapore found a novel way of encapsulating copper slag into concrete, reducing the use of natural sand in cement production and avoiding landfilling that used to ...
Copper Slag is an aggressive abrasive frequently used in new steel and steel maintenance applications. Its bulk density and angular shape give it an aggressiveness that provides clean, fastcutting action, considerably increasing production rates.
Sustainable Construction. During smelting, a molten pool of copper forms at the bottom of the furnace while a layer of impure metal, which is the slag, is drained off from the top. The copper slag is then quenched using industrial or sea water. Sometimes, it is left to cool by the air. For every ton of copper produced about ton of slag is generated.
Copper slag abrasive is dense enough to be reclaimed via a Cyclone separator in coarser sizes only. It has a 115 to 120#'s/cubic foot. THIS IS A HIGHER DENSITY THAN COAL SLAG AND WILL THUS BLAST FASTER THAN COAL SLAG, AND YOU CAN RECLAIM IT A COUPLE OF TIMES AS WELL.
a partial replacement of sand with copper slag. The sand was replaced from a minimum of 0% to a maximum of 50% with copper slag. A total of five combinations were studied for M20 concrete mix. Sand was Partial replaced with copper slag in proportions of 0%, 10%, 20%, 30%, 40% 50%. The Compressive Strength was calculated at
copper washing plant. copper washing plant excellent mining crushing machinery products or production line design, the company is committed to building the Chinese brand mine crushing and processing machinery, mainly crusher, mill, sand making our products (copper washing plant) in more than one hundred of the worldsales of countries and ...
much sought after natural river bed sand. Copper Slag At present about 33 million tonnes of copper slag is generating annually worldwide among that India contributing 6 to million tonnes. 50 % copper slag can be used as replacement of natural sand in to obtain mortar and concrete with required performance, strength and durability.
An experimental investigation was conducted to study the effect of using copper slag as a fine aggregate on the properties of cement mortars and concrete. Various mortar and concrete mixtures were prepared with different proportions of copper slag ranging from 0% (for the control mixture) to as fine aggregates replacement.
Jun 06, 2017· Though she warns that with higher levels of replacements (100 per cent) there might be some bleeding issues and, therefore, she recommended that up to 80 per cent copper slag and ferrous slag can be used as replacement of sand. Bottom ash. India is currently producing in excess of 100 million tonnes of coal ash.
replace cement and/or aggregates, such as ﬂy ash, steel slag, copper slag (CS), and recycled concrete aggregates—is a growing trend in many countries around the world. Singapore is no exception; for example, the Green Mark Scheme—a local green building rating standard—awards points to construction projects that make use of green concrete.
furnace at KCM, Zambia Chikashi Konkola Copper Mines plc, Chingola, Zambia Keywords: Pyrometallurgy, furnace, bath agitation, regression analysis, entrainment Abstract – This paper presents the results of linear regression analysis of the influence that each component of slag has on the losses of copper in slagcleaningfurnace slag.
Replacement with copper slag may result 20% higher strength to that of control concrete for 50% replacement. Around 10 million tonnes of GBFS is currently being generated in the country from iron and steel industries. 2 Silicomanganeseis smelted in electric or a blast furnace, the process creates ferromanganese and silicomanganese.
also maximum at 40% replacement of copper slag for 28 days of curing. So the replacement of 20% to 40% of copper slag is generally useful for better strength values in M30 grade of concrete. REFERENCES  Brindha, D and Nagan, S (2010). "Utilization of copper slag as a partial replacement of fine aggregate".
Jan 02, 2014· More details: Get the price of machines: Zenith Mining and Construction Machinery Co ...
copper slag as a replacement of sand. The M50 grade concrete used was designed by using modified ACI method. There are 5 concrete were prepared with different proportions of copper slag as a replacement of sand ranging from 45% to 60%. This mixes were evaluated for compressive strength, split tensile strength and flexural strength.
