Question
B. How is everything in FIGURE 1.1 related C. According to the Minerals Education Coalition, every American born in 2012 will consume 978 pounds (80.7 kg) of copper in his/her lifetime (www.mineralseducationcoalition.org). Analyze the three parts of FIGURE 1.1 listed below, and do your best to answer the questions based on what you observe. 1.1A: Aster satelite images of Escondida mining region, Chile. How could geologists use these images, at this scale of observation, to find new sources of copper ore? 1.1B: Ground view of Escondida open pit mine. How can geologists and miners locate copper ore when they view the mine at this scale of observation? 1.1D: Minerals of Escondida open pit mine. What must be done with these ore minerals to provide you with the copper you need? D. REFLECT& DISCUSS Analyze FIGURE 1.1A, ASTER satellite images of Chile's Escondida Mine and vicinity. This is primarily a mine for copper ore minerals, from which copper is extracted. Some silver and gold are also extracted from the same ore. The ore is mined from large open pits. Notice how these pits appear in the images. 1. Imagine that you are a geologist who has been hired by Escondida Mine to find the best location for a new pit. Which location. A. B, or C, is probably the best site for a new pit? What evidence and critical thinking process lads you to this conclusion What plan of scientific investigation would you carry out to see if the location you chose above is actually a good source for more copper ore? 2.Explanation / Answer
B.In first half of figure 1.1 we have seen the ground view of the mines and in the right half of the we have seen the satelite image of the mines so as we know in satelitic image there is special colour and pixel for every material so we can corelate both ground view and satelitic image.Then in the next half we saw the boulders of the mines containing copper ore minerals and from them we extract copper to form copper coin and then copper is used in computet also.
C.1.1A:-As the satelite images indicate a colour for a special type of object from this image geologist can have the knowledge of the area of the mines and they can presume in which portion of the mines we can find more copper .To know the distance in the real mines geologists have to use the scale given in the image.
1.1B:-As in ground view we can have the detailed sttucture and patern of the mines so we can calculate the copper ammount also.To do that we have to identify the ore minerals and their tonnage factore.In ground view a geologist can viee the colour of ore minerals to guess the mineral and then to test its copper content.
1.1C:-As in this mines two type of ore minerals are found i.e. malachite[Cu2CO3(OH)2] and azurite[Cu2(CO3)2(OH)2] .As per the chemical formula these two minerals are complex ore minerals with hydroxy group present so to get copper we have to remove the carbon-hydrogen-oxygen from the ore mineral by chemical analysis.
