How is copper obtained from it's sulphide ore write the balance chemical equation?
When sulphide ore is heated in air it is converted into copper oxide and SO2 is left. Again, copper oxide is then reduced to copper on heating( for equation, refer 10th CBSE text, pg no. 51)
What do you call a rock that contain s a high concentration of valuable mineral?
it is called an ore
What is an arsenopyrite?
An arsenopyrite is a silvery-grey ore of arsenic - a mixed arsenide and sulphide of iron, chemical formula FeAsS.
Do much of the worlds copper is contained in the mineral ore?
Chalcopyrite which is a copper iron sulphide mineral with formula CuFeS2.
What is concentration of ores called?
Concentration of ore Unwanted rocks, sand and grit from the mineral ore are called gangue or matrix. These have to be removed so that the mineral ore is concentrated with higher percentage of metal. Ores are mined from deep within the earth's crust in the form of rocks. The minerals are embedded in these rocks. The rocks are first crushed into smaller pieces by crushers. Then they are ground to powder by ball mill and other processes so that powdered ore is obtained. Depending on the type of ore, hydraulic washing, froth floatation process, magnetic separation and chemical separation techniques are applied for concentrating an ore.
Name the process used to concentrate a sulphide ore?
froth floatation process
Why is the froth flotation method selected for the concentration of sulphide ores?
This method is based on the principle of the difference in the wetting properties of the ore and the gangue particles with the water and oil. This method is used for that metals whose ore gets preferably wetted by the oil and the gangue by the water. The sulphide ores preferably wetted by the oil and the gangue with the water. Hence this method is suitable for the concentration of the sulphide ore
How is sphalerite formed?
Sphalerite is sulphide ore, it is concentrated by froth flotation and then subjected to roasting to convert the sulphide ore to oxide ore. The oxide ore is reduced to zinc using carbon monoxide or coke.
What is the origan of the element Mercury?
mercury come from cinnabar ore or mercuric sulphide (HgS) mercury come from cinnabar ore or mercuric sulphide (HgS)
Can mercurous sulphide be landfilled openly?
yes certainly.mercuric sulphide is nothing but cinnabar ore of mercury and sulphur.
What metal is extracted from Cassiterite?
Cassiterite is the main ore of Tin.
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.
What is an argentite?
An argentite is an alternative name for silver sulphide, a primary ore of silver.
Is galena sulphide ore of lead?
Yes, it is Lead(II) sulfide = PbS
What is a bismuthinite?
A bismuthinite is a soft bismuth sulphide mineral, an important ore for bismuth.
What mineral is zinc obtained by?
Zinc is obtained from zinc blende/sphalerite ore (zinc sulphide)
How is copper obtained from it's sulphide ore write the balance chemical equation?
When sulphide ore is heated in air it is converted into copper oxide and SO2 is left. Again, copper oxide is then reduced to copper on heating( for equation, refer 10th CBSE text, pg no. 51)
