Is silver found in pure form?
Silver is most commonly found as its oxide in their ores.
What are the various step involved in metallurgy?
1. Concentration of the ores. 2. Converting the concentrated ore to its oxide. 3. Extracting the metal from its oxide. 4. Purification of the metal.
How are sulfide ores turned into oxides?
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.
In what form does polonium occur in nature?
Polonium is a very rare chemical element accompanying uranium in ores (probably in the form of an oxide).
Why is cryolite used in the manufacture of aluminium?
It's used as a flux. It melts at a significantly lower temperature than aluminum oxide ores, but they will dissolve in molten cryolite. This means less energy is required to extract the aluminum from the ores than if they had to be heated to their melting temperatures.
What are two general types of hydrothermal deposits?
Sulfide ores and oxide ores
Are oxide ores dissolved in acid solutions?
Yes, it is possible.
What is all ores of aluminium with chemical equation?
aluminium oxide
What does the mining metal ores mean?
Extracting a metal oxide from the ground
What is the name of the important family metal ores containing oxygen?
One name would be "Oxides", as in iron oxide (Rust), aluminum oxide, zinc oxide, and titanium oxide, to name a few.

Is an ilmenite with 7 percent titanium oxide good?
No - that is low yield - there are ores richer than that around the world
How is cobalt obtained?
Cobalt is obtained by heating its ores to produce cobalt oxide. The cobalt ores are: cobaltite, smaltite, chloranthite, and linnaeite. Once those ores are heated, the remaining compound is then heated with aluminum to release the pure metal.
What non-silicate group contains iron ores?
Iron ore minerals would be included in the oxide mineral grouping.
How are sulfide ores turned into oxides?
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.
What are the ingredents for iron ore?
Iron mainly comes from iron oxide ores, though less common ores such as the sulphide are used as available. There are usually many contaminants, such as silicon and phosphorous that need be removed by the refining process.
