The result makes clear, can be restrained on certain level by starch but the siderite with weaker inhibition in hematite and quartz exterior adsorption overspreads a lid, it is the main reason that causes Dong Anshan to contain carbonate iron ore to turn over floatation difficulty.

"It occurs rarely as a free metal, occasionally in natural alloys, and in hundred s of minerals and ores, including hematite, magnetite, limonite, and siderite."

The depressive behavior of (NH4)2 SiF6 on iron-containing silicate gangue, aegirine, in hematite flotation with sodium oleate as collector was studied.

It demonstrated that the hydroxy organic acids substituted with-OH,-SH at α—C such as lactic acid, Hydroxy-acetic acid, mercapto-acetic acid, glyconic acid have good selectivity for separation of hematite and aegirine pka values of organic acids fall down because of the-I inductive effect of-OH or-SH, and lie at the pH range between two minerals point-zero-charge. As a result, the depression ability of them was enhanced, and a cyclo-pentyl chelate was formed when this organic acids acted with Fe〓 on the minerals surface.

The A and B components remanent magnetization were loaded by goethite and maghemite respectively, the C component remanent magnetization was carried by the magnetite in the sandstones and were loaded conjunctly by the magnetite and hematite in the mudstones and muddy sandstones.
