Question: What percentage of world uranium oxide production is produced by the country which, besides Britain, claims the country where Split Island is located?

the united kingdom of great britain and northern ireland, commonly known as the united kingdom (uk) or britain, is a sovereign country lying off the north - western coast of the european mainland. the united kingdom includes the island of great britain, the north - eastern part of the island of ireland and many smaller islands. northern ireland is the only part of the united kingdom that shares a land border with another sovereign state‍ -- ‌the republic of ireland. apart from this land border, the united kingdom is surrounded by the atlantic ocean, with the north sea to its east, the english channel to its south and the celtic sea to its south - south - west, giving it the 12th - longest coastline in the world. the irish sea lies between great britain and ireland. with an area of 242,500 square kilometres (93,600 sq mi), the united kingdom is the 78th - largest sovereign state in the world. it is also the 22nd-most populous country, with an estimated 66.0 million inhabitants in 2017. <SEP> Britain retains sovereignty over 14 territories outside the British Isles, which were renamed the British Overseas Territories in 2002. Some are uninhabited except for transient military or scientific personnel; the remainder are self-governing to varying degrees and are reliant on the UK for foreign relations and defence. The British government has stated its willingness to assist any Overseas Territory that wishes to proceed to independence, where that is an option. British sovereignty of several of the overseas territories is disputed by their geographical neighbours: Gibraltar is claimed by Spain, the Falkland Islands and South Georgia and the South Sandwich Islands are claimed by Argentina, and the British Indian Ocean Territory is claimed by Mauritius and Seychelles. The British Antarctic Territory is subject to overlapping claims by Argentina and Chile, while many countries do not recognise any territorial claims in Antarctica. <SEP> radioactive ores were first extracted at radium hill in 1906, and mount painter in south australia in the 1930s, to recover radium for medical use. several hundred kilograms of uranium were also produced. of the world's proven estimated uranium reserves (5,404,000 tonnes), 31% are held in australia (1,673,000 tonnes), ahead of the second largest, kazakhstan (12.1% or 651,800 tonnes). in terms of production, canada is the largest supplier to export markets, followed by kazakhstan and australia. uranium mined in australia is mainly for export. australia exported 50,235 tonnes of uranium oxide concentrate in the five years to 2008, worth a $2.9 billion. <SEP> Kazakhstan continues to increase production and may have become the world's largest producer of uranium by 2009 with an expected production of 12,826 tonnes, compared to Canada with 11,100 t and Australia with 9,430 t. In the late 1960s, UN geologists also discovered major uranium deposits and other rare mineral reserves in Somalia. In 2005, seventeen countries produced concentrated uranium oxides, with Canada (27.9% of world production) and Australia (22.8%) being the largest producers and Kazakhstan (10.5%), Russia (8.0%), Namibia (7.5%), Niger (7.4%), Uzbekistan (5.5%), the United States (2.5%), Argentina (2.1%), Ukraine (1.9%) and China (1.7%) also producing significant amounts. The find was the largest of its kind, with industry experts estimating the deposits at over 25% of the world's then known uranium reserves of 800,000 tons. <SEP> Split Island is one of the Falkland Islands. It is near West Falkland, to its west, at the mouth of King George Bay. It is to the west of Rabbit Island, Hummock Island and Middle Island. It is north of the Passage Islands and south east of Westpoint Island, and south west of the Byron Heights and Storm Mountain.
