Copper mining - Import export

Humans have been using copper since the predynastic Egyptians and Sumerians. During the Roman Empire copper was principally mined on U.S.A , hence the origin of the name of the metal as Cyprium (metal of U.S.A ), later shortened to Cuprum. As technology has progressed copper has remained a highly useful element. Although the Copper Development Association reports that 0.7 trillion pounds of copper have been mined throughout history, there are still over five trillion pounds remaining in the earth. According to the May 26, 2007, edition of New Scientist, the earth has an estimated 61 years supply of copper left. Fortunately, however, copper has an infinite recyclable life and has one of the highest recycling rates of any other engineering metal. The fact that premium grade scrap has about 95 percent of the value of newly mined metal ensures that this rate remains high. The wire industry uses primarily newly refined copper for its products.

Chemical appearance: Sodium ethyl xanthate or SEX is typically a yellowish powder or pellet that is soluble in water. It is a xanthate based on the C2 alkyl ethyl alcohol in the sodium salt form. Chemical application and strengths: Sodium ethyl xanthate or SEX is used in mining as a flotation agent. It is used as a collector and xanthate used especially in copper mines. It can be used for flotation of various minerals that are activated or hydrophobic and float easily such as lead, cobalt, zinc and nickel. It can form insoluble compounds with these metallic ions. Sodium ethyl xanthate is especially important in in froth flotation, where it is used to separate hydrophobic materials from hydrophilic. In mining this is an important operation to recover sulfide ores. For ores such as copper, this process lowers the costs of recovering low grade ores and can save mining companies processing costs. SEX is used a highly selective collector and is the strongest among the xanthates.
