·Characteristics of Sand casting Sand casting is the most versatile among the manufacturing methods and gives engineers the freedom to design complex parts from an unlimited number of metals and Over 70% of all metal castings are produced via this process; Sand casting can be produced in a wide range of sizes from small statues to parts
·Ores found on the earth contains many impurities like sand rocks and grit in them which are collectively known as Gangue The concentration of ore is a method of removing gangue particles or other impurities in order to purify the ore This process is also called Ore dressing and is a very crucial step to obtain a pure metal from ore and to extract
Aluminum processing Ores Refining Alloying Aluminum is the third most abundant element on Earth s surface Only oxygen and silicon are more common Earth s crust to a depth of 16 km 10 miles contains 8 percent aluminum Aluminum has a strong tendency to combine with other common elements and so rarely occurs in nature in the metallic form
·The most important disturbances to the process are ore hardness changes and feed size variations An input output model of the process can be wr itten in a vector
