World market of tantalum
Are you interested in the world market for tantalum from the supplier company AvecGlob? Here you will find interesting information on this topic.
World reserves of tantalum
Tantalum is found in a number of oxide minerals associated with granite and other alkaline igneous rocks. In the world geological inventory there is no shortage of tantalum, therefore known reserves correspond to the forecasted demand. Nevertheless, the simplest methods of extracting tantalum from ore raw materials are already largely exhausted.
In the 1980s, tantalum was obtained as a by-product of tin smelting. Almost 40% of the world production of 236 000 tons was Thailand and Malaysia. Tin ore of Malaysia and Thailand is rich in tantalum, therefore, as a result of tin smelting, the initial raw materials were obtained, which contained 110… 15% tantalum. By 1994, the share of this method of obtaining tantalum decreased to 20%.
Pegmatites continue to be the largest source of tantalum. They are usually found in quartz and other minerals containing tin, tantalum and rare earth elements. The Greenbushes pegmatite near Perth in Western Australia is one of the world’s largest resources, and is extracted by the Australian company Sons of Gwalia. It accounts for more than one-third of the world’s tantalum production.
Another important source of tantalum is Africa, where tantalum (from predominantly alluvial resources) is restored by artisanal technologies.

Promising world tantalum production centers
Tantalum-containing ores contain elevated concentrations of this metal and can easily be converted into commodity concentrates.
It is known that some alkaline granites and related rocks contain tantalum and niobium in large amounts, albeit at low concentrations. Modern mechanized mining in open quarries can make recovery of metals at very low concentrations economically viable. Tantalum-bearing granites often contain stocks that are much larger than those found in pegmatites.
Particularly large resource of the apogee used to produce tantalum is the Pitinga deposit in the Amazon, operated by the Brazilian company Paranapanema. Another apogranite resource considered for production is in the northwest of Saudi Arabia. This is the Ghurayyah deposit, originally explored in the 1970s as a source of uranium. Today, the British company Tertiary Minerals plc is carrying out a feasibility study to extract tantalum from granite. The Ghurayyah deposit is the world’s largest single accumulation of tantalum. With an estimated estimated mineral resource of more than 385 million tonnes at a depth of 250 meters, the deposit, estimated at 245 g / t of Ta 2 O 5 and 2840 g / t of Nb 2 O 5, contains more than 208 ml of tantalum pentoxide.
It is estimated that Ghurayyah contains more tantalum than the combined published reserves at the Greenbushes and Wodgina mines in Western Australia, the two largest tantalum mines in the world, which currently make up about 30% of the world’s tantalum minerals.
Supplier — AvekGlob Company — offers to purchase tantalum and its alloys in a variety of brands in the assortment. Products can be bought at a price formed on the basis of European and world standards. Implementation is possible in bulk and retail, for regular customers, a flexible system of discounts operates.
