Embodiment 1

[0011] Embodiment one, lignin chelated secondary iron manganese concretion sand to make poultry food health care sand:

[0012] The secondary iron-manganese concretion sand grains are soaked with a sulfonate solution containing lignin with a mass concentration of 40-50%. Due to the inherent tiny pores formed by the life activities of manganese bacteria in sand grains, it can penetrate into lignin, and lignin is chelated with metal elements such as iron and manganese deposited on the outer layer of the nucleus. No air bubbles in the soaking solution, that is, the reaction is over, filter out the iron-manganese structure sand from the soaking solution, add 2% of the total dry weight of salt, and mix a small amount of vanillin as a flavoring agent, it can be used as a health care for poultry sand. The health-care sand is rich in trace elements that can be taken in by poultry; the sand particles can help poultry gastrointestinal peristalsis, enhance the digestion ability of poult...

Embodiment 2

[0013] Embodiment two, lignin chelated secondary iron-manganese concretion sand to make feed additive:

[0014] The solution containing lignin with a mass concentration of 40-50% is used to soak the secondary iron-manganese nodule sand grains after acid analysis with hydrochloric acid to form a slurry with a material-to-water ratio of 1:1, which is used as a feed additive for poultry and livestock. Add 3-4% of the total feed for breeders; add 2-3% of the total feed for laying hens; add 5-6% of the total feed for fattening pigs; add 3-4% of the total feed for fur rabbits. Compared with the control group, the weight gain rate of poultry, laying hen egg production rate and feed utilization rate in the experimental group were all improved, but the feed cost was reduced, which improved the economic benefits.

Embodiment 3

[0015] Embodiment three, the microfertilizer based on iron element is produced with lignin chelated secondary iron-manganese concretion sand;

[0016] (1) Acidify the secondary ferromanganese concretion sand, use the waste liquid of the sulfuric acid washing steel in the iron and steel plant, and add scrap iron chips in the waste liquid, so that the pickling waste liquid becomes a ferrous sulfate saturated solution (sulfuric acid appears in the solution Ferrous green crystals), then add secondary ferromanganese concretion sand in this solution, acidify to powder;

[0017] (2) In the solution containing lignin mass concentration of 40-50%, add the iron-manganese concretion sand after the above-mentioned acidification, control the material-water ratio 1: 1, mix and stir, then add the sugar residue filter mud of the sugar factory (mainly The composition is calcium carbonate) to neutralize the mixed material, so that the pH value reaches between 6.5-8, and then the attapulgite cla...

Abstract

The invention provides a method for preparing agricultural goods through chelating ferromanganese nodule sand by lignin. The agricultural goods prepared with the method are bird-eating health sand, feed additive, trace element fertilizer and soil conditioner. The preparation method comprises the following steps: secondary ferromanganese nodule sand is soaked in solution containing the lignin, or the secondary iron-manganese nodule sand after acidification is soaked therein, or the soaked materials are further neutralized. The method adopts the solution and industrial waste acid containing the lignin to be acted with the ferromanganese nodule sand which is discarded by people for a long term, thus leading the ferromanganese nodule sand to have utilization value to serve for the human society; the preparation process is non-slag production; the feed additive prepared has weight-increasing effect on livestocks and has the effects of improving the soil and fertility as a micro-fertilizer, thus being a measure to achieve recycling agriculture and ecological regression; and compared with similar products, the prepared agricultural goods have lower price.

Description

technical field [0001] The invention relates to the development and utilization of secondary iron-manganese nodule sand lean ore, in particular to a method for preparing agricultural materials by chelating secondary iron-manganese nodule sand with lignin. Background technique [0002] Secondary iron-manganese nodule placers are mainly distributed in ocean and lake areas. Although they contain iron, manganese, cobalt, nickel and other multi-metal elements and silicate minerals, the content of these elements is relatively low. The same kind of secondary iron-manganese nodule poor sandy ore is contained in Hongze Lake and its surrounding areas in my country. The ore body is mainly composed of nodule-like particles entrained with sediment and shells, and the contiguous pieces form sedimentary embankments. As early as the 1970s, the relevant departments of the provincial and municipal governments had established a project for the utilization of iron-manganese nodule placer, its m...
