Benefits of technology

This patented technology describes two methods used by certain companies called Vetservators (Victorator) Inc., who are trying to recycle waste from mineral deposits containing valuable materials such as uranium or ceramics. They found that they could make better ways to dispose off these wastes without causing harmful impact upon their environment. By utilizing this new type material instead of just one extra element like other elements added into fertilizers, we can achieve economies with regards to both landfill management and greening efforts. Additionally, there were also systems where engineers took advantage of the ability to reuse existing sources of natural gas and electricity. Overall, our technical effect will be improved efficiency and sustainability in treatments involving radioactive substances.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving methods for recovering valuable materials from acid rock deposits without leaving any residue behind during their extraction processes.

Embodiment 1

[0026] A kind of ionic rare earth heap leaching field, the composition contained in its raw soil is as follows:

[0027] Nitrogen and phosphorus elements: ammonia nitrogen 151mg / kg, total nitrogen 416mg / kg, total phosphorus 145mg / kg;

[0028] Precious metals: manganese 375.1mg / kg, palladium 3.48mg / kg, yttrium 89.9mg / kg, lanthanum 55.6mg / kg, neodymium 27.9mg / kg, cerium 25.8mg / kg, dysprosium 7.4mg / kg, gadolinium 5.4mg / kg , Praseodymium 6.1mg / kg;

[0029] Soil pH: 4.01.

[0030] A systematic method for repairing an ion-type rare earth heap leaching field, the specific steps are as follows:

[0031] S1. Fertilizing and turning the soil: filter the domestic sewage treatment plant to the organic sludge with a moisture content of 60%, evenly spread it in the heap leaching field, the application rate is 600 kg per mu, and the plowing depth is 100cm;

[0032] S2, separate seedling planting: adopt the vetiver that has grown for one year and the root system length is greater than 3 me...

Abstract

The invention provides a system method for repairing an ionic rare earth dump leaching mine field. According to the method, a mode of restoring while gaining is adopted, by planting vetiver grass, nitrogen and phosphorus resources in mine field soil can be fully utilized, water and soil loss and ammonia nitrogen in rare earth tail water are reduced, the regreening effect is achieved, the soil property of the mine field can be improved, the vetiver grass absorbs and enriches precious metal, precious metal can be recycled after the vetiver grass is incinerated as fuel, meanwhile, the vetiver grass planted after mine field restoration can be used for breeding and extracting essential oil, organic fertilizer composted by waste is reused for vetiver grass planting, systematic restoration and treatment are achieved, and meanwhile collaborative development of ecological benefits, social benefits and economic benefits is achieved.
