Primary industries are those that harvest or extract raw materials from nature; they include agriculture, oil and gas extraction, logging and forestry, mining, fishing and trapping.

The industrial origin approach is an approach to computing a nation's GNP based on adding up the gross value of primary, secondary and tertiary industries. These industries are agricultural, manufacturing and service. This approach is just one of many that can be used to try and create an estimate of the true GNP of a nation. However, if done properly, all methods should generate the same GNP figure.

Titanium is obtained through mining its ores, mostly in the form of titanium oxide in the minerals rutile and ilmenite, from open pits. The titanium oxide in these minerals must first be purified, then converted to titanium chloride, before titanium can be obtained. Titanium is the ninth most abundant element in the Earth's crust, but its mining and processing must be managed with expense and environmental concerns in mind.
