Iron Ore - Dissertation Example However, most of the reserves that harbor such natural ores have now been depleted. Pig iron is made out of iron ore. This pig iron is one of the main raw materials used in the making of steel. Iron ore is believed to contribute more to the global economy than any other commodity in the world. Hematite is the main iron ore in the Brazilian miles (Axinn 2006). In the global world, metallic world is virtually unknown. It is the fourth most abundant element in the world, though, silicate or carbonate minerals are the vastest minerals. Formidable and extremely energy intensive barriers often are used to separate supremely pure iron from other minerals (David 2006). Before the industrial revolution, most of the iron used was obtained from goethite, which was widely available. Societies during the pre historic times used laterite as the main source of ore. Most of the iron ore used by the emergent industrialized societies was obtained from haematite. These deposits are often called the nat ural ores. The increased iron ore demands in conjunction with the depletion of the most high quality haematite in the United States of America led to development of low quality sources of iron. This happened especially after Second World War. These lower sources of iron require beneficiation to improve on their quality. Magnetite on the other hand, is used due to its magnetic properties. Therefore, it is able to be separated easily from other minerals and was able to produce high quality concentrate with minimal impurities. The mining of these iron ores vary considerably with the type of ore that is being mined. Currently, there are four types of ores of iron being worked on. The business of mining ore is often a low margin one due to the significant low level of iron than other base metals. It is expensive to mine, meaning it is extremely capital intensive. It requires a heavy investment in infrastructure such as rail transport in order to transport the ore from the mining sites to the freight ship. Therefore, mining of ore is concentrated among the majority few. The world leading and largest iron producer is Brazil. This mining corporation is referred to as vale. Other developed countries follow the line due to the high costs involved in the mining and transportation of the ore. My research question arises from my curiosity to find out how iron ore is produced, consumed and distributed in the global market. This is because I understand that the cost involved in its mining process and transportation is quite high. Therefore, I would like to find out how extreme the ore is mined and the processes used in the mining process (Edward 2007). Executive Summary This research is concerned with the production, consumption and distribution of iron ore globally. In other words, it seeks to show candidly the cycle of iron ores from its mining and separation from impurities until the moment it is processed and distributed to the global market for various uses. The researc h shows all the methods used in extraction of these iron ores and how it is separated from other metallic substances or impurities. It also reveals research rationale that is used in carrying out my research. In addition, this research paper has addressed my research question based on the prevailing international market and all the key findings that emerge (Institute 1997). Moreover, the methodology I use to address the research question is emergent in the research paper. The paper

Interracial Relationships - Essay Example Hence, acculturation has been in vogue particularly from the second half of the last century, and people have not only given up the policy of ethno-racial hatred, but are also entering into matrimonial relationships with the individuals belonging to the races that were considered to be inferior and rival ones for the last many centuries. â€Å"Of course racial mixture is nothing new – it has been the history of the world. What stand out as novel are the forms of political contestation gathering around the topic of ‘mixed race’† (Parker & Song 2001, 1) 1 It is a reality beyond suspicion that there certainly exists a significant proportion of society that views his race as inferior one in comparison to others and enters into marital knot with some other ethnic group in order to conceal its complex on the one hand, and produce comparatively better generation in the form of bi-cultural children on the other. However, the history is replete with several examples of interracial love affairs, which end into happy marital union without displaying the slightest signs of inferiority complexes in the background. As we approach the twenty-first century biracialism and biculturalism are becoming increasingly common. Skin color and place of birth are no longer reliable signifiers of one's identity or origin. (O’Hearn 2008) The literary pieces, including â€Å"How It Feels to be Coloured to Me†, by Zora Neale Hurston, express the sentiment and feelings of the Blacks while their interaction with the majority white community of the USA. Similarly, Amiri Baraka's play â€Å"SOS† (1964) also serves as a gorgeous expression of the pain one feels out of the miseries and complexes the minority ethnic groups undergo while living far from their native land. The contemporary era has witnessed tremendous growth and developments in the field of communications in the aftermath of rapid technological advancements. Consequently, travelling fro m one part of the globe to the others has become vehemently popular, swift and easy. People move to the advanced regions, including the USA and Europe, in the pursuit of superior employment, health, education and career prospects, which has forced the people of divergent racial groups to live in the multi-cultural society and to work in the multi-racial organizations. Gone are the days when the African Americans were brought as slaves in chains for the labor, toil and substandard services from their native land, and were looked down upon by the Arabs, Turks, White Anglo Saxon Population (WASP) and others as inferior creature. As a result, an overwhelming majority of the Blacks, Chinese and Japanese marry the whites taking into a step towards their growth and progress in the social hierarchy. The Blacks were humiliated and abhorred by the whites and they were not allowed to travel and inter-dine even with the whites, and they were deprived of even basic necessities of life. The same was the fate of the yellow races including the Chinese, Japanese, Koreans and others. However, the situation took drastic turn and the brave and courageous Blacks launched the Harlem
