Recent Progress in Electric Furnace Titanium Slag Processing and Utilization: A Review
نویسندگان
چکیده
Titanium slags produced through ilmenite electric furnace smelting contain 60–80%TiO2, a vital titanium resource in the industry. The processing and utilization of slag is faced with many challenges, such as complex mineral structures, high requirements, severe environmental pollution, heavy additives energy consumption. This study aims to review technologies for slag. First, we analyze characteristics from different regions. Then, discuss detail methods using progress can be divided into two areas: preparation dioxide high-quality titanium-rich materials. These include H2SO4 leaching, HCl fluoride sulfur roasting–leaching, alkaline oxide oxidation reduction phosphorylation ammonia decomposition leaching. Further development roasting–leaching extraction recommended.

The Phase Composition of Electric Furnace Slag
Elementary and phase composition as well as micrography of the electric furnace slag were examined. The base of slag is made from phases containing Fe, Mn and Ca. Grains differ in size and shape, they cling together to form bigger or smaller agglomerates, depending on separated fractions. Relative distribution of identified phases in separated fractions is presented and the possibility of phase...

متن کاملA review on recent applications of brushless DC electric machines and their potential in energy saving
Electric motors are the largest consumer of world electric energy, consuming more than twice as much as lighting, the next largest consumer. Electric motors account for between 43 and 46% of all global electricity consumption approximately. They give rise to about 6 040 Mt of CO2 emissions. End‐users approximately spend USD 565 billion per year on electricity [1]. In recent years...
