    Jan 02, 2012 High alumina silica ratios ( 1) in the processed ore burden (sinter) create problems in blast furnace smelting and therefore, there is an urgent need for reducing the alumina content (and thereby reducing the alumina silica ratio in the blast furnace feed) in such high alumina iron ores.Aluminum processing Aluminum processing Ores Aluminum is the third most abundant element on Earth’s surface. Only oxygen and silicon are 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.
