Answer:
rosting
Explanation:
Oxide ores. These ores contain metals in oxidized forms. Unlike sulfide ores, oxides need much more energy to achieve melting. For this reason, the hydrometallurgical approach is generally used to refine these ores.
Ore processing consists of the following stages: crushing and grinding of the ore. ... addition of lime to the ore, and cyanide solution to the slurry, to leach the gold and silver into solution. addition of carbon to adsorb (attach) dissolved metals and remove them from the slurry.
In roasting ore is heated in the presence of excess of oxygen or air. This method is employed for sulphide ores. Example: ZnS (sphalerite) and Cu2S (chalcocite).
