PAPER OPEN ACCESS Effects of electron beam smelting on

Electron beam smelting has been applied in refining nickel-based superalloys, which has been proved to be an effective method for removing inclusions. The inclusions are aggregated at the circular region (last solidified region) of the ingot surface periphery where Get price

Ferronickel

The combined nickel yield into ferronickel is 88% to 93%. Among alternative technologies of ferronickel smelting and refining, blowing molten iron and nickel ore mixture with reducing gas (Krasheninnikov and Leontiev, 2001) might be mentioned. The addition of 20% limestone allowed an increase of nickel content in the metal to 70%, in slag 0.1% Get price

OUTOTEC FLASH SMELTING TECHNOLOGY

Flash Smelting is a natural choice for higher-grade copper concentrates due to its lower capital investment costs. Outotec Direct Nickel Flash Smelting (DON) This process enables high-grade nickel matte to be produced using a single flash smelting furnace. It allows higher recovery of nickel, cobalt, and precious metals than Get price

slag from smelting of copper nickel ores

Copper Slag an overview | ScienceDirect Topics. Copper slag, or fayalite slag, is a by-product obtained during the matte smelting, converting and refining of copper (Fig. 7.11). 54,59 It has been estimated that for every tonne of copper produced, about 2.2 tonnes of slag is generated, 60 as a consequence of the relatively low grades of copper concentrates now available.

Environmental Code of Practice for base metals smelters

The carbonyl process is used for refining crude nickel oxide. Carbon monoxide and the crude nickel react to form nickel carbonyl at high pressure. The volatile and highly toxic nickel carbonyl is refined by separation of solid impurities. With further heating, the carbon monoxide separates, and high-purity nickel powder or pellets are formed.
