Sulfide ores are usully converted to oxides by heating them in air, this process is called roasting.
During this process, metal sulfide is turned into metal oxide and sulfur dioxide is given out as a by-product.
Oxide ores are a type of mineral ore that contains metal oxides, typically formed through weathering processes. These ores are often easier and cheaper to process compared to sulfide ores, as they can be readily leached using methods such as hydrometallurgy. Common examples include iron ore (hematite) and aluminum ore (bauxite).
Most ores contain mineral compounds, such as oxides, sulfides, carbonates, and silicates. These compounds typically contain metal elements that can be extracted through mining and processing.
Copper: Mined primarily as chalcopyrite, an important source of copper. Gold: Extracted from gold ores such as quartz and pyrite. Iron: Mainly obtained from hematite and magnetite ores. Zinc: Usually found in sphalerite, a zinc sulfide mineral. Aluminum: Mainly sourced from bauxite ore, a mixture of hydrated aluminum oxides.
Most iron ores are iron oxides or iron sulfides. Iron ores are also usually hydrated (i.e. includes water of crystallization). A variety of other metal ores (e.g. copper, zinc, lead) are sometimes mixed with iron ores. In much lower concentrations, almost any element (except the inert gases) might be found.
Sulfide (S^2-) is a negatively charged ion formed from sulfur that has gained two extra electrons. It is commonly found in minerals and ores, as well as in various biological processes. Sulfide compounds can be toxic and have a strong odor, such as in hydrogen sulfide gas.

Sulfide ores and oxide ores
Copper is commonly found in nature in the form of sulfide ores, such as chalcopyrite, bornite, and chalcocite. It can also be found in the form of oxides, carbonates, and native copper, which occurs as pure copper metal in its natural state.
In pyrometallurgy, roasting is primarily conducted through three methods: sulfurizing roasting, oxidizing roasting, and chloridizing roasting. Sulfurizing roasting involves adding sulfur to convert metal oxides into sulfides, while oxidizing roasting helps in transforming sulfide ores into oxides by introducing oxygen. Chloridizing roasting utilizes chlorine to convert metal oxides into chlorides, facilitating further extraction processes. Each method is tailored to enhance the recovery of specific metals from their ores.

yes , sulphur have ores. such ores are called sulphide ores. these sulphide ores are purified by the process called roasting. this is the process which involves heating with oxygen and then reducing into original metals. eg: copper sulphide, zinc sulphide, etc.
Copper: Mined primarily as chalcopyrite, an important source of copper. Gold: Extracted from gold ores such as quartz and pyrite. Iron: Mainly obtained from hematite and magnetite ores. Zinc: Usually found in sphalerite, a zinc sulfide mineral. Aluminum: Mainly sourced from bauxite ore, a mixture of hydrated aluminum oxides.
Ores are refined to produce manufacturing grade metals and chemicals for consumer use.
Most iron ores are iron oxides or iron sulfides. Iron ores are also usually hydrated (i.e. includes water of crystallization). A variety of other metal ores (e.g. copper, zinc, lead) are sometimes mixed with iron ores. In much lower concentrations, almost any element (except the inert gases) might be found.
No, galena is not a mineral oxide. It is a sulfide mineral composed of lead and sulfur. Oxides are minerals that are composed of oxygen combined with a metal or other element.
Sulfide (S^2-) is a negatively charged ion formed from sulfur that has gained two extra electrons. It is commonly found in minerals and ores, as well as in various biological processes. Sulfide compounds can be toxic and have a strong odor, such as in hydrogen sulfide gas.
Yes, it is true that many metals, including copper, lead, and zinc, are extracted from ores containing sulfide minerals. These sulfide minerals are often rich in the desired metals and undergo processes such as roasting and smelting to extract the metals. The presence of sulfur can complicate processing, but it also allows for efficient metal recovery when managed correctly.
