What Is Nickel Smelting? (with picture) - InfoBloom

Nickel ore must melt until it becomes a product known as liquid matte, which is usually around 45 percent nickel. Nickel smelting is the process that nickel ore goes through to eventually remove impurities and leave just the nickel metal. While the ores can come

Factors affecting nickel recovery from slags produced ...

2009-8-26  Nickel is recovered as a by-product of the platinum-producing process operated by AngloPlatinum. The metal is mined mainly as sulphide minerals contained in platinum ores. These passthrough the concentrating, smelting and converting process route and nickel is finally recoveredby electrowinning. Smelting of the concentrated ore in the electric furnace produces a melt with ahigh slag to matte ratio. The resulting furnace slag is granulated and later milled and floated torecover matte. A project was initiated to investigate the distribution of nickel in the slag in orderto improve recovery. Slag samples were examined using a combination of chemical andmineralogical techniques. The granulated slag was found to consist mainly of a silicate glassphase, which reflects the composition of the molten slag in the furnace. Nickel occurs as freematte granules, as matte phases locked inside the glass, and in the glass phase itself. Whereasnickel in the matte is as sulphide, most of the nickel
