Continuous Update of Beneficiation Reagent

FOR IMMEDIATE RELEASE
(Free-Press-Release.com) December 20, 2011 -- The progress of the mineral processing reagents on China's iron ore beneficiation process development especially mention iron down the development of silicon work plays an important role.China cement mills The domestic research of the iron ore flotation reagents mainly of collector and inhibitors, of collector and divided into anion and cation of collector of collector, chelating three main types of collector.

Dressing workers in China in recent years is mainly to the fatty acid kind,Cone crusher oil sulfonic acid salts on modification and mixed use, make its selective improved obviously, your catch ability strengthens, especially in anionic reverse flotation of collector made significant progress. New and high efficient anion of collector SH-37, MZ-21, RA-515 respectively in the army sets the mill ansteel, mill and east of qidashan anshan iron ore sintering red mill applications such as a success,Cement mill price the grade of iron concentrate 66% ~ 67% above, tons of concentrate reagent cost reduced by 15% or more, the adaptability of the increase of temperature, and the economic benefit is remarkable. Used for the magnet concentrate quality drop of miscellaneous ask new high efficiency of collector MD-28, MH-80 respectively in southern mining companies and taiyuan jianshan iron ore and application, the magnet concentrate grade increased to 69% above. The newly developed MH-88 special effects of collector used to choose wuyang iron mountain temple don't lean hematite stone,Impact crusher with the grade of iron concentrate 65% above, the metal recovery of 72.Secondary cone crusher56% and a good index.

Cationic of collector is mainly amine kind of collector, used for flotation silicon minerals, including the fat amine and ether amine. Domestic by amine of collector of the concentrator is not much,Cone crusher manufacturer and potions species less, mainly with twelve carbon fat amine and mixed amine primarily. Angang bow fault the mill used the new cationic of collector YS-73. In addition, wuhan university of technology development of new cationic of collector GE-601, has the good low temperature resistance, the efficiency high characteristic,Cement rotating dryer not only can solve problems of twelve amine, and don't need through the magnetic separation behind directly behind the tail, which can simplify the process flow.

Chelation of collector can and mineral surface of metal ions to form stable chelates, its selective than fatty acid kind of collector obviously improved. Such as water-soluble carboxy methyl starch in the army sets the mill angang used in industrial production, greatly simplifying the preparation process of drug and reduce the cost of production, and benefits in 3 million yuan of above. Iron concentrate desulfurization MHH-1 special effects as activator for removal of iron concentrate sulfide ore especially magnetic strong, the flotability of poor magnetic pyrite has obvious effect, compared with other activator, MHH-1 has consumption, low cost, desulfurization effect obvious characteristics, etc. At present, the products have been in several mining successful application, so the products of research for iron ore concentrate mention iron drop sulfur providing new way
