No; iron ore is mixed with copper and smelted; the ore needs to be refined to extract pure iron. You cannot make a tool out of ore, but rather with pure iron.
The name of pure iron is just "iron." When iron is in its pure form, it consists of iron atoms without any other elements or impurities mixed in.
Iron is the mineral. Iron is an element and as such, is not composed of any other materials, though iron ore comes out of the ground mixed with many other minerals. The ore must then be processed to extract the pure iron for practicle use.
Iron ore is processed through a series of steps to extract the valuable metal. First, the ore is crushed and ground into small pieces. Then, it is concentrated using magnetic separation or flotation to separate the iron from other minerals. Finally, the iron is smelted in a furnace to remove impurities and obtain the pure metal.
Iron sulfide can be split into iron and sulfur through a process called roasting. When heated in the presence of oxygen, iron sulfide undergoes a chemical reaction that converts it into iron oxide and sulfur dioxide. The iron oxide can then be further processed to obtain pure iron.
Iron weighs 0.284 pounds per cubic inch, while cast iron is about 0.25-0.27 pounds per cubic inch, due to how it is made and processed. So pure iron is heavier
Pure iron is homogeneous.
Crude iron refers to impure iron that has not been refined or processed. It typically contains elements such as carbon, silicon, sulfur, and phosphorus, which need to be removed in order to produce pure iron. Crude iron is usually obtained from iron ore through processes like smelting or direct reduction.
Wrought iron is the closest to pure iron you can get, as far as i know, with it being 99-99.8% Fe. There are many processes for producing wrought iron. See http://en.wikipedia.org/wiki/Wrought_iron for more details.

Pure iron is rarely found in its pure form in nature because it readily reacts with oxygen to form iron oxide (rust). However, iron can be purified through industrial processes to obtain pure iron for various applications.
If it is pure iron then by definition there is no carbon or anything else present in it, just iron.
