Conversion of non-ferrous sulfides |
摘要 |
The invention relates to the smelting or converting of particulate sulfide material, such as nickel or copper sulfide. A molten seed bath of smelted or converted material is provided in a reaction vessel. Particulate sulfide material is injected into a reaction vessel below the surface of the melt. Top blowing with an oxygen-containing gas generates heat and brings about the oxidation of the sulfides with a significant decrease in the amount of dust generated. Optional bottom stirring with a non-reactive gas such as nitrogen may further increase efficiency.
