Abstract
The invention relates to the technical field of phosphate and compound fertilizers, and discloses a treating technology for an acid liquor generated during a phosphorus ore dressing process by an acid method as well as an ore-dressing process, comprising the steps of using sulfuric acid as a phosphorus ore cleaning agent to remove magnesium, filtering slurry subjected to magnesium removal to obtain a solid-phase object, namely cleaned phosphorus ore for producing phosphoric acid, adding liquid ammonia into filter liquor for neutralizing to obtain sediments, and finally preparing a compound fertilizer, wherein a solid matter obtained after filtering is magnesium ammonium phosphate, and a crystal substance obtained by concentrating the filter liquor is ammonium sulfate. The process disclosed by the invention can effectively remove metallic oxides such as magnesium in phosphorus ore, and solves the problem that acidolysis cleaned liquid is difficult to process.
Description
Technical field
The present invention relates to phosphorus compound fertilizer technical field, particularly relate to treatment process and the application of the acid solution produced in the ore dressing of a kind of phosphorus ore acid system and ore dressing process.
Background technology
China's phosphorus ore grade is poor.Rich ore Rock Phosphate (72Min BPL) only has 1,600,000,000 tons, accounts for 9% of Rock Phosphate (72Min BPL) total amount, and is mainly distributed in expensive, Hubei Province two province, and remaining more than 90% all belongs to mid low grade phosphate rock.Therefore, the demand of phosphoric acid and high-concentration phosphate compound fertilizers production could be met after the phosphorus ore of most of China has to pass through beneficiation enrichment.In numerous ore-dressing technique, because of flotation process strong adaptability, the advantage such as the efficiency of separation is high, technique is simple, be widely used, become the most effective technique of preparing.But floatation process also exists certain problem, produce a large amount of flotation tailingss, the rate of recovery of phosphorus is low, consumes great lot of water resources, contaminate environment, there is dam break danger etc.
The major impurity of China's phosphorus ore and what have considerable influence to Wet-process Phosphoric Acid Production is magnesium, de-magging also becomes the emphasis of flotation of phosphate rock, is secondly the burning materials such as calcium, iron, copper.In the forming process of phosphorus ore, can occur to hand over phenomenon, namely some tiny rhombspars can be inlaid in phosphatic rock main body ore deposit, only adopt present physical concentration to be difficult to be isolated to these rhombspar fine particles, need to adopt chemical de-magging method.The method of phosphorus ore chemistry de-magging has two classes before: Re Fa and acid system.Since last century the seventies, the research carrying out de-magging with acidic substance is a lot, but effect is not fine, and subject matter is: the loss of (1) phosphorus is large; (2) treatment process that data regular poor (3) purification decomposed solution is not good.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides treatment process and the application of the acid solution produced in the ore dressing of a kind of phosphorus ore acid system and ore dressing process, this technique can remove the metal oxides such as the magnesium in phosphorus ore effectively, and solve acidolysis scavenging solution be difficult to process problem.
The technical solution adopted in the present invention is:

2) step 1) gained breeze through handling equipment in purification reactor, first mixed bacteria liquid is added, stir, leave standstill 48 hours, then add 98% sulfuric acid, 100 turns/min stirring reaction 12 hours, then filter is delivered to, filtration obtains solid materials and liquid material, and solid materials is purify qualified phosphorus ore, delivers to phosphoric acid workshop; The addition of described mixed bacteria liquid is 1/20th of powdered ore quality; The addition of described 98% sulfuric acid is 1/10th of powdered ore quality;
3) step 2) gained liquid material enters neutralization reactor, pass into liquefied ammonia to neutralize simultaneously, enter filter after sufficient reacting and carry out solid-liquid separation, wherein, liquid solid-liquid separation obtained concentrates, then concentrated solution carries out crystallization, and crystal drying is obtained material 1, and Crystallization Separation liquid is for subsequent use; Carry out oven dry in the Solid Conveying and Melting that solid-liquid separation obtains to drying machine and obtain material 2;
4) by material 1, material 2, potassium humate, straw powder, the peat composed of rotten mosses, oyster shell whiting and step 3) gained Crystallization Separation liquid mixing and stirring, join in double-screw extruding pelletizing machine, pelletizer outlet establishes dicing machine, is cut off by bar shaped fertilizer, packaging Ji get composite fertilizer;
Wherein, material 1, material 2, potassium humate, straw powder, the peat composed of rotten mosses, the mass ratio of oyster shell whiting and step 3) gained Crystallization Separation liquid is 3:3:2:1:1:1:5.
Described auxiliary agent is obtained than mixing and stirring according to the quality of 1:1 by talcum powder and kerosene.
Described mixed bacteria liquid by Acidithiobacillus ferrooxidans strain GF liquid and micrococcus luteus liquid according to the volume ratio mixing and stirring of 2:1 and get final product.
The beneficial effect that the present invention obtains mainly comprises:
Present invention process can remove the metal oxides such as the magnesium in phosphorus ore effectively, and solve acidolysis scavenging solution be difficult to process problem; Treatment process whole process of the present invention is pollution-free, does not have the mine tailing problem of floatation process, possesses good economic benefit, and environmental protection and energy saving; The present invention selects suitable microbe species and proportioning, make good symbiosis between microorganism, there is between them synergy and mutual supplement with each other's advantages preferably, and can effectively can by metallic element lixiviate out, obtain the metal ion of solubility, decrease sulfuric acid usage quantity, provide cost savings; Tropina by vitriol oil breaks down into amino acids, can chelated metal ions for the preparation of chelating amino acids metal, substantially increase fertilizer efficiency, improve soil nutrient.
