Magnetizing roasting of leucoxene concentrate

Nov 20 2011The phase transformations occurring during magnetizing roasting of leucoxene concentrate in the temperature range 600–1300C are studied It is demonstrated that in the temperature range 600–800C only iron oxides are reduced to a metallic state at temperatures above 800C combined reduction of iron and titanium oxides takes place Get price


Solar thermal energy

Overview Solar thermal collectors are classified by the United States Energy Information Administration as low- medium- or high-temperature collectors Low-temperature collectors are generally unglazed and used to heat swimming pools or to heat ventilation air Medium-temperature collectors are also usually flat plates but are used for heating water or air for residential and commercial use Get price
