| titleOfInvention | A kind of filter aid and preparation method thereof being separated by solid-liquid separation for hematite concentrates |
| abstract | A kind of filter aid and preparation method thereof being separated by solid-liquid separation for hematite concentrates, formula components press mass fraction are as follows: 0.1~5 part of acrylic acid, 0.1~2 part of acrylamide, 3~10 parts of starch, 2~20 parts of iron powder, 0.1~5 part of hydrogen peroxide, 10~80 parts of hydrochloric acid, 100 parts of water；The preparation method comprises the following steps: (1) prepares raw material；(2) acrylic acid and starch are added into water, stirs evenly, is warming up into starchiness, adjusts pH value；(3) iron powder is added into hydrochloric acid；(4) acrylamide and hydrogen peroxide are added after mixing, is warming up to 50 ± 2 DEG C of 1~2h of reaction.Filter aid of the invention is small to equipment corrosion；Dosage is small when use, use cost is low, and transport, use, storage are highly-safe. |
