unwanted rock was removed as a slag and the coppercontaining minerals were collected as a matte. Sulfur dioxide was emitted in this process and no attempt was made to capture it. There was only one exception, this being a process that was developed in Norway and which became known as the Orkla Process whereby elemental sulfur was produced. In this process, coke was charged together with the ...

produce crushed, slowcooled, sulphurdeficient nickelcopper matte rich in platinum group metals (PGMs), gold, and base metals for despatch to the Magnetic Concentration Plant at the Base Metals Refinery. Throughout its history, the smelter complex has been continuously upgraded in line with increasing production demand, changing feeds, environmental initiatives, .
· This study aims at evaluating the effect of ultrafine granulated copper slag (UGCS) on hydration development of blended cement and mechanical properties of mortars. The UGCS with the median particle size of μm and BET surface area of m2/g was used as a cement replacement to prepare blended cements. Hydration heat emission of blended cement and mechanical .
Slag is a byproduct of smelting (pyrometallurgical) ores and used metals. Broadly, it can be classified as ferrous (byproducts of processing iron and steel), ferroalloy (byproduct of ferroalloy production) or nonferrous/base metals (byproducts of recovering nonferrous materials like copper, nickel, zinc and phosphorus). Within these general egories, slags can be further .
Slag Milling Coppervetura Mining Machine. Slag milling can be broadly egorized as ferrous ironsteel and nonferrous copper leadzinc depending on the industry from which they come non ferrous slags make up only 12 of the total annual production described below are the main types and uses of slag and flotation of slow .

· Smelters using slag milling and flotation for slag cleaning generally operate under conditions where most of the copper in slag would tend to form Cu 2 S upon cooling, although some metallic copper may still form via reaction Ideally, the slag should be slow cooled to allow most of the copper to form larger matte prills (over 30 μm in size), leading to minimal copper levels in the .
Workability of slag cement pastes is remarkably improved when using 1 h of highenergy slag milling. This result is consistent with slag finesse trend with respect to milling time and with the improvement of GBFS reactivity. The substitution of 45% of cement (CEM I ) by GBFS is only beneficial at the condition of performing highenergy milling for at least 1 h. Keywords: .

· Copper slag is a byproduct of the copper smelting industry. Generally, – tons of copper slag is generated per ton of copper produced in the whole process, depending on the properties of the copper sulfide concentrates and the operating,2 It is estimated that approximately 12 million tons of copper slag is discharged into the environment annually in China.
slow cooled copper slag. Greater understanding, improved performance "The best flotation performance was achieved with the 50:50 addition ratio of DSP 330 and SIBX, with a copper recovery of % for a head grade of % and a cutoff copper grade of 2425%." Pengfu Tan, Alberto Galvez, Lucya Yunus– Mount Isa Mines Flotation cell where copper concentrate is .
strongly enriched in Cu, Pb and As and were cooled very slowly. In addition, the presence of Cu1+bearing phases (delafossite CuFeO 2 and mcconnelite CuCrO 2) in these slags indies highly variable redox conditions in the historical shaft furnaces. Furthermore, the CaPb arsenates found in the matrix indie that these slags have undergone an alteration process in the .
