1. Granite is a course-grained intrusive silicic igneous rock, it is a nonmetallic resource. Therefore they are not malleable nor a conductor. Even though granite contains metal ions, the minerals in granite contain relatively little metal, so it would cost more to separate the metal from the granite.

Is granite nonmetallic?

Granite is a mineral, and is not assigned status as a metal or nonmetal. The metal/nonmetal characteristic is usually assigned to a chemical element rather than to chemical compounds or, as is the case with granite, groups of these compounds.There will be some metals in all granite. Though this mineral is largly made of silicon dioxide (SiO2), a number of metal compounds will be present in small amounts within the crystaline structure. Aluminum, potassium, sodium, iron and other metals, and even traces of uranium, can be found in granite.


Why is metal useful to people?

How was the discovery of metal useful to early man?

The discovery of metal was useful to early man because it allowed for the creation of tools and weapons that were stronger and more durable than those made from stone or wood. This advancement improved hunting, agriculture, and warfare, leading to advancements in civilization and technology. Metal also enabled humans to develop new metalworking techniques and trade for valuable metals with other societies.


Will sulfuric acid dissolve granite rock?

Yes, sulfuric acid will attack granite. We're only going to approach this from a general perspective, but we can answer the question. Granite is what is called a felsic mineral, and much of it is composed of compounds that are individually composed of a metal plus silicon plus oxygen. The acid will, in general, target the metal, and will combine with it. This will tear it away and out of the crystal structure of the rock, and it will effectively destroy the structure of the granite.
