Mining & Metals
Mining is the extraction of valuable minerals or other geological materials from the earth, usually from an orebody, lode, vein, seam, reef or placer deposits. These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain any material that cannot be grown through agricultural processes, or created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Mining of stones and metal has been a human activity since pre-historic times. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and final reclamation of the land after the mine is closed. Mining operations usually create a negative environmental impact, both during the mining activity and after the mine has closed. Hence, most of the world's nations have passed regulations to decrease the impact. Work safety has long been a concern as well, and modern practices have significantly improved safety in mines. Levels of metals recycling are generally low. Unless future end-of-life recycling rates are stepped up, some rare metals may become unavailable for use in a variety of consumer products. Due to the low recycling rates, some landfills now contain higher concentrations of metal than mines themselves.

Malaysia is a federal constitutional monarchy located in Southeast Asia. It consists of thirteen states and three federal territories and has a total landmass of 330,803 square kilometresseparated by the South China Sea into two similarly sized regions, Peninsular Malaysia and East Malaysia. Peninsular Malaysia shares a land and maritime border with Thailand at the north and maritime borders with Singapore at the south, Vietnam at the northeast, and Indonesia in the west. East Malaysia shares land and maritime borders with Brunei and Indonesia and a maritime border with the Philippines and Vietnam. The capital city is Kuala Lumpur, while Putrajaya is the seat of the federal government. With a population of over 30 million, Malaysia is the 44th most populous country. The southernmost point of continental Eurasia, Tanjung Piai, is in Malaysia. Located in the tropics, Malaysia is one of 17 megadiverse countries on earth, with large numbers of endemic species. Malaysia has its origins in the Malay kingdoms present in the area which, from the 18th century, became subject to the British Empire. The first British territories were known as the Straits Settlements, whose establishment was followed by the Malay kingdoms becoming British protectorates. The territories on Peninsular Malaysia were first unified as the Malayan Union in 1946. Malaya was restructured as the Federation of Malaya in 1948, and achieved independence on 31 August 1957. Malaya united with North Borneo, Sarawak, and Singapore on 16 September 1963 to become Malaysia. Less than two years later in 1965, Singapore was expelled from the federation. The country is multi-ethnic and multi-cultural, which plays a large role in politics. About half the population is ethnically Malay, with large minorities of Malaysian Chinese which also form the second largest community of Overseas Chinese in the world, Malaysian Indians, and indigenous peoples. The constitution grants freedom of religion but recognises Islam as the established religion of the state. The government system is closely modelled on the Westminster parliamentary system and the legal system is based on common law. The head of state is the king, known as the Yang di-Pertuan Agong. He is an elected monarch chosen from the hereditary rulers of the nine Malay states every five years. The head of government is the Prime Minister. The country official language is Bahasa Melayu or commonly known as Malay language. English remains as an active second language. English proficiency in Malaysia has been highly ranked as the second best in Asia after Singapore and 13th best in the world as of 2017. Since its independence, Malaysia has had one of the best economic records in Asia, with its GDP growing at an average of 6.5% per annum for almost 50 years. The economy has traditionally been fuelled by its natural resources, but is expanding in the sectors of science, tourism, commerce and medical tourism. It is also one of the few developing countries to subsidise heavily on education and healthcare. Its citizens are entitled to free public education up to secondary education level and public tertiary education fees are subsidised as much as 90%. Basic healthcare services at government run clinics with prescription cost RM1. Disabled, senior citizens and public school students are entitled to free healthcare. Its healthcare services have been highly regarded as one the best in the world and the UN Development Programme has called Malaysia healthcare system "a model to other developing countries". Malaysia's unprecedented and recent rapid development has attracted millions of migrant workers from across Asia in the recent years. The majority of whom are undocumented, which the Malaysian government is struggling to combat. Its treatment and crackdown on migrant workers has often been criticised by international human rights watchdogs. Today, Malaysia has a newly industrialised market economy, ranked 4th largest in Southeast Asia and 38th largest in the world. With a GDP per capita of $9,766 and an HDI of 0.78 currently, Malaysia is classified as an emerging economy by the World Bank. The International Monetary Fundalso classifies Malaysia as an emerging and developing country. It is a founding member of the Association of Southeast Asian Nations, the East Asia Summit, and the Organisation of Islamic Cooperation. Malaysia is also a member of the Asia-Pacific Economic Cooperation, the Commonwealth of Nations, and the Non-Aligned Movement. In 2017, Malaysian citizens had visa-free or visa-on-arrival access to 164 countries and territories, ranking the Malaysian passport 5th most powerful in the world.
