Pyrometallurgy of copper
{"Image DocumentName": "Pyrometallurgy of copper", "Image ImageDescription": "Reminder: Pyrometallurgy is the use of heat to reduce the mineral to the free metal, and usually involves 4 main steps: Calcination: thermal decomposition of the ore with associated elimination of a volatile product. Roasting: a metallurgical treatment involving gas- solids reactions at elevated temperatures. Smelting: a melting process which separates the chemical reaction products into 2 or more layers. Refining: treatment of a crude metal product to improve its purity. Eg. Of a roasting rxn: CuS + 1.5O2 \u2192 CuO + SO2.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
