Roasting (metallurgy) - Wikipedia

Roasting is a process of heating a sulfide ore to a high temperature in presence of air. It is a step of the processing of certain ores.More specifically, roasting is a metallurgical process involving gas–solid reactions at elevated temperatures with the goal of purifying the metal component(s). Often before roasting, the ore has already been partially purified, e.g. by froth flotation.

Zinc smelting - Wikipedia

Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point.At temperatures typically used for smelting metals, zinc is a gas that will escape from a furnace with the flue gas and be lost, unless specific ...

Extraction of Nickel from Garnierite Laterite Ore Using ...

Laterite nickel deposit is formed by the weathering and leaching of nickel-bearing peridotite in tropical or subtropical regions. As a nickel ore, it was discovered by Garnier in New Caledonia in 1863, so the ore is called “garnierite”—a magnesium-based nickel silicate. Because the ore is red due to the oxidation of iron after weathering, it is called laterite. In fact, in the upper part ...
