Titanium is obtained from various ores that occur naturally on the Earth. Ilmenite (FeTiO3) and rutile (TiO2) are the most important sources of titanium. According to USGS, Ilmenite accounts for about 92% of the world’s consumption of titanium minerals. World resources of anatase, ilmenite and rutile total more than 2 billion tonnes.
From surgical titanium instruments to orthopedic titanium rods, pins and plates, medical and dental titanium has truly become the fundamental material used in medicine. Common titanium applications in terms of medical industry: • Hip and knee joints. • Bone screws. • Bone plates. • Dental implants. • Surgical devices. • Pacemaker cases.
Recycling of tungsten in high speed steel is high, and a typical melt contains 60% to 70% scrap, including internally generated scrap. On the other hand, recycling in such applications as lamp filaments, welding electrodes and chemical uses is low. The common tungsten extraction methods are surface (or open pit) mining and sub-surface (or ...

The world reserves of bismuth containing ore stands at 320,000 tonnes and the reserve base is estimated to be 680,000 tonnes. The mined bismuth content production in 2013 can be seen in the table below. In 2013, worldwide total bismuth mining production was 7,600 tonnes, falling 0.7% (600 tonnes) compared with last year’s figure of 8,200 tonnes.
It is estimated that if 87 large rare earth mines were restarted, their production could meet the total commercial demand in the world for 280 years. Russia. Rare earth minerals are also rich in Russia, with USGS reporting in 1993 that its reserves were 19 million tonnes. However, in recent years the figure is unknown.
A side-project band started by Chris Barnes (then a part of Cannibal Corpse) and Allen West (of Obituary).Six Feet Under was originally intended to remain a side-project, but after Barnes was ejected from Cannibal Corpse, Six Feet Under became his priority, subsequently moving the band from a side-project to the long-running act they are today.
