Technology Progress of Refractory Ore Beneficiation

The long-term shortage of squeeze ore resources in chinaware is an incontestible fact, rational phylogenesis and spend of complex refractory campaign ore resources to ease the contradiction between supply and demand of push ore in China and to safeguard the economic security of Chinas nerve industry is of great significance. China refractory iron ore beneficiation technology were reviewed, for both of the complex nature of the peckish Iron characteristics and problems of proposed future research directions. Sustained and stable development of the iron and steel industry is an urgent need for stable, adequate, type supply of iron ore raw materials. Into the 21st century, as the domain of a function economic recovery and structural adjustment of the acceleration, especially in Chinas rapid economic development, stimulating the sustained higher(prenominal) growth of Chinas steel industry, Chinas steel output signal has ranked first in the world steel turnout in cc3 reached 220 million tons of steel production in 2004 exceeded 270 million tons.

With the expanding scale of Chinas steel industry, China has surpassed japan to become the worlds largest importer of iron ore in 2003, imported one hundred fifty million tons of iron ore, imported iron ore reached 200 million tons in 2004, imports of iron ore The number accounted for more(prenominal) than half of the total of finished iron ore demand in China. Due to increasing iron ore demand and supply gap, domestic help and international iron ore prices skyrocketing, a substantial rise in sea freight transport system in utmost(a) tension. The improvement of the iron ore import dependency has become a significant risk for the economic security of Chinas steel industry. Therefore, an urgent need to rely on technological advances to maximise the use of existing domestic iron ore resources, especially mineral processing technology and therefore can not use complex refractory iron ore and the current can chair advantage of the quality and utilization of low iron ore, add-on storage efficiency,...
