According to the suplimentary demands the price you pay for a product is determine both by its availability and by consumer demand for the product. On the basis of the principle, which mineral do you think have a higher value, iron containing mineral or feldspars? Some one please help me with this question
Sixty percent of the mineral content on Earth is fieldspars. There is a lot of it. About the only commercial usage is in ceramics, like pottery, tiles.
Iron on the other hand is difficult to find, in commercial quanities. To get rich, find an iron ore mountain and mine it. If you find a fieldspar mountain, build a house and enjoy the view. There is much demand for iron.
