Sulphidation of copper coolers in PGM smelters i Abstract Corrosion problems of copper waffle coolers are experienced in Platinum Group Metals (PGM's) smelting furnaces. The copper cooler wear mechanism was studied through a postmortem analysis of the refractory corrosion products that were removed from a PGM smelter. Postmortem samples were

From the it was observed that the copper slag admixed concrete showed higher corrosion rates than normal concrete in various percentages of replacements. The corrosion rate of copper slag admixed concrete increases as percentage of copper slag increases. The corrosion rate can be controlled by coating the bar with Zinc Phosphate paint.

Copper slag blasting edia/grit is manufactured of the granulated slag of copper refineries, and used for blastcleaning of metal surface. Copper slag has also gained popularity in the building industry for use as a fill material. Contractors may also use copper slag in place of sand during concrete construction.

It has the physical properties similar to the fine aggregate, so it can be used as a replacement for fine aggregate in concrete. By the replacement of 40% of copper slag (by weight) as replacement for fine aggregate. And by the replacement of 20% of fly ash (by weight) as replacement for cement will produce a .

slag melts into the tested refractory bricks and formation of Cr(6+) compounds. The molten copper partially oxidizes during corrosion test by air and penetrates into bricks. Interactions among periclase (MgO) and chromite (FeCr 2 O 4) grains with the melt Na 2 O·2SiO 2 and copper oxides makes possible to form several compounds ( Cu 2 MgO 3, CuCrO 4, CaCrO 4

Wrought iron is an iron alloy with a very low carbon (less than %) content in contrast to cast iron (% to 4%). It is a semifused mass of iron with fibrous slag inclusions (up to 2% by weight), which gives it a "grain" resembling wood that is visible when it is etched or bent to the point of failure. Wrought iron is tough, malleable, ductile, corrosionresistant and easily welded.
