Purpose of the present invention is exactly in order to overcome described the deficiencies in the prior art part, a kind of preparation method of rare-earth phosphate fertilizer is provided and adopts the resulting rare-earth phosphate fertilizer of this method.
The objective of the invention is to realize in such a manner: will have the N that contains that produces simultaneously in the rare earth production technology now, K, REO and Cu, Zn, Mn, the salts solution of Sr etc., can regulate the water-soluble solid amendment with physical behavior such as diversity of fertilizer, with granularity less than 180 purpose rock phosphate powder thorough mixing, adopt the production method of common normal superphosphate, add the vitriol oil (98%), 100-130 ℃ of reaction 3-6 hour, its product removes and contains secondary calcium phosphate, outside the rare earth, also contain the micro-phosphoric acid salt of multiple solubility, vitriol, muriate or nitrate.Described rare earth production technology has sulphate process, chloride process or nitrate process.
The ore that described rare earth production technology uses is to produce normally used ore in the rare earth method, for example can be monazite ore, bastnasite ore, Baotou rare earth ore and ionic ore.
Described salts solution is different different because of ore type, for example can be chloride soln, nitrate solution, sulfate liquor, or the mixture of above-mentioned two kinds or multiple solution.
Described salts solution H
+Concentration is 10
-4.5To 5N.
According to situations such as soil and crops, when trace element can not satisfy actual needs in its product, can when producing rare earth, add and contain these micro-ores, these ores can generate the salt of solubility with acid or alkali reaction, for example Cu, Zn, Ni etc. can add copper glance stone, zink sulphide stone etc. respectively.
Described amendment is made up of 50% (weight) REO, 30% compound, MgO10% and the CaO10% that contains P.
The above-mentioned raw materials proportioning is: less than 180 purpose rock phosphate powder 800-900 weight parts, its Rock Phosphate (72Min BPL) generally contains P
2O
5Be 26-38%; The solution 98-200 weight part that contains REO, nitrogen, potassium and trace element.Its middle-weight rare earths 0.01-4.0 grams per liter, nitrogen 0.1-30 grams per liter, potassium 0.1-30 grams per liter and various trace elements 0.1-10 grams per liter; Vitriol oil 370-540 weight part; Solid amendment 2-10 weight part.
Because the rare-earth phosphate fertilizer production method is a kind of method with Rare Earth Production method and the combination of normal superphosphate fertilizer production method, so rare-earth phosphate fertilizer is to be main component with the normal superphosphate, and contain the fertilizer of various nutrient elements such as rare earth, nitrogen, potassium, copper, manganese, zinc, nickel, strontium, boron, its normal superphosphate content height is as P
