Cassiterite

compound. In the earth’s crust, pure tin is not abundant. It was estimated that only 1 to 2ppm of pure tin exists in the earth’s crust. Tin usually exists in a form of tin oxide (SnO2), which is commonly none as Cassiterite. The colour of cassiterits are, brown, black or reddish brown Cassiterite is formed in 2 types of geological earth structure, which is in the hydrothermal veins and in pegmatite, both by granite intrusion. In the hydrothermal veins contains hot fluid with dissolve metal. The hot fluid

Justin Taylor Mrs.Lewis Tungsten Title of Your Report Tungsten, also known as wolfram, is a chemical element with symbol W and atomic number 74. The word tungsten comes from the Swedish language tung sten, which directly translates to heavy stone. Its name in Swedish is volfram, however, in order to distinguish it from scheelite, which in Swedish is alternatively named tungsten. A hard, rare metal under standard conditions when uncombined, tungsten is found naturally on Earth only in chemical

Such is depicted clearly and efficiently in “Congolese Tin: At The Heart For The New Scramble For Africa”, a documentary filmed by Journeyman Pictures on the date of May 29, 2006. Despite the fact that the state withheld an abundant supply of a cassiterite, the workers received little to no pay for their labour, reason being that the state was in a vulnerable position due to the “bloodthirsty [and] devastating war” they had endured. This provided states that were more developed with an opportunity

problems for the nation that received assistance was Brazil’s Polonoreste development program. The Polonoreste development program was to build and improve the roads and highways through the rainforest. The goal of this was to make the transport of cassiterite, used in the production of tin, easier and to open up the western part of Brazil for development and population. The negative outcomes were the rampant destruction of rainforest to slash-and-burn agriculture and the disturbance and destruction of

While the term “conflict mineral” can be used to refer to any mineral resource being exploited by a belligerent faction in order to perpetuate hostilities, it is most commonly associated with columbite-tantalite, cassiterite, wolframite, and gold ore, collectively known as 3TG minerals.i These ores, used to produce tantalum, tin, tungsten and gold, respectively, comprise a multi-billion dollar market fueled by the growing demand for electronics and other products related to the technology industry

Republic of Congo was a “personal” matter on most fronts for the King and because of all the natural resources that came with gaining the land that was Congo. Just to name a few of the natural resources, there are diamonds, gold, copper, cobalt, cassiterite (or tin), along with oil and coltan. So in taking over the once free state of Congo the King not only gained the natural resources, but in his demented mind he also gained the people or work force to harvest these resources. Some of the long lasting

I’ve selected The Home Depot store for this discussion. The Home Depot is the world’s largest home improvement retailer with reported sales of $24.8 billion for the second quarter of fiscal 2015. (The Home Depot, Inc. 2015). In 2014 the sales growth in the year was $4.4 billion, and store sales were up 5.3 percent. The digital channel accounted for over $1 billion of the stores total growth. In 2014 the store achieved the highest net earnings in the Company’s history. The company’s growth is due

zones. Eastern Congo is one of the principal origins of conflict mineral. The humanitarian crisis in Eastern Congo is caused by arms groups that control the production of different minerals. The most important of them are Gold ore, and the 3 T’s ( Cassiterite for Tin, Wolframite for Tungsten, Coltan for Tantalite).These minerals

Many Americans have the luxury of purchasing new electronics almost every year. Something that is ignored, since it has become so natural, is exactly how their little devices had come to their lives and what happens when it is thrown away. In a more perfect world, the production of electronics would that of an ethical process, but it is unfortunately not that case. It all starts with the harvesting of raw materials. When bringing up the idea of a “100 percent ethically sourced” smartphone, Caroline

The Democratic Republic of Congo has changed a lot due to child labor. The children of Congo work hours mining gold, cassiterite, and most commonly cobalt as well as use the children as soldiers to fight in wars. The Democratic Republic of Congo has not done anything to prevent child labor until very recently. The country’s economy has been crashing which is why they used child labor to start with. About twenty-five percent of children between the age of five to fourteen, which is over four
