How is iron usually separated from its ores?
By heating iron ore and a source of Carbon
How are minerals extracted from their ores?
metals are extracted from their ores according to their reactivity series.firstly, metals that are more reactive that carbon are extracted by electrolysis whic is breaking the compounds down using electricity.secondly, metals that are less reactive than carbon are extracted by reduction in which carbon is added to the metal ore, carbon react with oxygen and the metal remain by itself pure.example: Zinc oxide + Carbon ----> Zinc + Carbon dioxideGold and Platinum are found in nature by themselves.
How does the heating with carbon monoxide process work when extracting minerals from its ores?
It can reduce the oxidation state of the mineral in the ore being heated.
What Methods Can Be used To Extract Metals From Ores?
There are three basic ways of treating metallic ores in order to extract their metal content. Pyrometallurgy is the treatment of metals and their ores by heat. Pyrometallurgy includes Roasting, which is the heating of ores in air or heating it with a reducing agent such as carbon (coke) or carbon monoxide. Pyrometallurgy is the oldest extractive process. In early day Nevada, carbon was obtained from pinyon pines, juniper trees or sagebrush. The wood was collected and heated in ovens which resembled beehives and these ovens became the "Beehive Ovens" found today near numerous old mining camps. The second basic way of treating metallic ore is electrometallurgy. In this method the metals are processed using electricity such as electroplating and electrorefining. Electric arc furnaces are used to make steel. Electrometallurgy is used when very high purity metal is needed. The third basic way of treating metallic ore is hydrometallurgy. This is a wet process as the name implies, where reactants are used in a water solution. This method has not been used on an industrial scale due to the high costs involved. However, as the concentration of desired metal becomes less in the ores mined, the wet processing of the more valuable metal ores becomes more feasible
How can carbon be used to extract a metal from its ore?
Metals are extracted from ores. An ore is a rock that contains enough of a mineral (metal compound) for the metal to be extracted from it. Most metals are extracted from an ore by reduction with carbon or by electrolysis.
Does sulfur have 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.
What metals are fairly reactive and found as ores?
potassium, nickel, carbon
Is iron usually separated from its ores?

What is the need of purafication of ores?
Pure metals have more uses than ores, rocks, from the ground. Ores cannot be made into pipes, wires, or sheets of metal for various uses. Unlike the Flintstones, we cannot make a car out of rocks. Purified metals are used to make the frame, the body panels, the electrical wiring etc. for the car.

Why do you mine metal ores?
Metal ores are used as resources from which metals may be extracted.
What are the important ores?
Their importance is that these ores can be extracted into metals .
Are ores and rocks minerals or metals?
Pure native metals are considered minerals. Mixed metals are considered alloys.
Is carbon mono oxide useful?
Carbon monoxide is useful as a reducing agent, in extracting some metals from their ores. It is also used in some organic synthesis.
How does the heating with carbon monoxide process work when extracting minerals from its ores?
It can reduce the oxidation state of the mineral in the ore being heated.
Do metals only come fron ores?
Yes, metals do only come from ores and pure metals also are found in the Earth's crust.
