A high energy ball mill (Pulverisette7, FRITSCH, supplied by Gulf Bio Analytical Group, Bani Malik District, 23223 Riyadh, Riyadh, Saudi Arabia) was utilized to mix the powders for 30 min as a ball milling time with a speed of 150 rpm. A 4 gm of the pure Ti and another 4 gm of the mixed Ti-Zr powder were pressed in two graphite dies.
1. Introduction. The reserves of vanadium-titanium magnetite in China are nearly tens of billion tons, and an astonishing amount of tailings will also be produced during the extraction of elements such as V and Ti, .As the waste residue after extracting vanadium from these tailings many times, extracted vanadium residue still contains abundant iron and titanium resources,, .
Vanadium in the form of vanadium oxide is a component in special kinds of steel that is used for automobile parts, springs, and ball bearings. Most of the vanadium used in the United States is used to make steel. Vanadium oxide is a yellow-orange powder, dark-gray flakes, or yellow crystals.
