This paper discusses on the present situation of and existing problems in the process of the heavy- medium system of Xiqu Coal Mine's Coal Washery, emphatically analyzes on the de- medium effectiveness, which provides reliable foundation for reducing the cost (the medium consumption of the system...
desiliconizationniobiumselective oxidationsoft blowingTo clarify selective oxidation of silicon prior to the other elements such as niobium, the pre-desiliconization process of low niobium hot metal has been experimentally investigated. Desiliconization experiments were carried out in a medium frequency ...
The present invention is coutnerfloating desiliconization process for diaspore type bauxite. Through raising the difference between diaspore and aluminosilicate ore, especially kaolinite, illite and pyrauxite, in surface hydrophilicity and hydrophobicity by using floating chemical and certain technological ...
the invention includes a first process of desiliconization at basic degree of 0.6 to 1.2 by supplying an oxygen source, a second process for conducting dephosphorization by supplying a CaO source so that the basic degree becomes 1.2 or more, a third process of separating dephosphorized slag an...
