High value element-containing and iron hydroxide-based raw material and application thereof

Abstract

The invention relates to a high value element-containing and iron hydroxide-based raw material and application thereof, and belongs to the technical field of resource recycle and hydrometallurgy. The high value element-containing and iron hydroxide-based raw material mainly comprises iron hydroxide, high value element compounds and combustible organic matters, wherein in terms of element, iron accounts for 3.5-45wt%; in terms of oxides, high value elements account for 2-32wt% altogether and Y (Fe3+) / TFe accounts for more than or equal to 54.47wt%; in terms of C, combustible organic matters account for less than or equal to 6.5wt%; the iron hydroxide-based raw material does not combust spontaneously at the temperature of lower than or equal to 200 DEG C. The high value element-containing and iron hydroxide-based raw material is powdery or in form of an easily-crushed briquette and has the advantages of being homogeneous in structure, unlikely in spontaneous combustion, convenient and safe in use and the like; fire hazards during transportation, loading and unloading, storage and production of an iron-based waste material are prevented and safe production is achieved; during using, the dissolution rates of the high value elements are high and the high value elements can be prepared into different products, so that the maximized utilization of resources is achieved and the development of circular economy is benefited.

Description

technical field [0001] The present invention relates to a ferric hydroxide-based raw material containing high-value element and its application. The invention belongs to the field of resource recycling and hydrometallurgy technology. Background technique [0002] In the production and use of iron-based alloy materials mainly composed of iron and high-value elements (hereinafter referred to as iron-based materials), a large amount of debris, leftover materials, slag materials, sludge materials, defective products, etc. containing high Materials with valuable elements (hereinafter referred to as iron-based waste). The iron and high-value elements in the iron-based waste are mainly in the form of simple substances and / or alloys; the high-value elements in the iron-based waste include at least one of rare earth, cobalt, nickel, titanium, copper, manganese, zinc and other elements kind. According to relevant data, these iron-based waste materials contain a large amount of rare...

Problems solved by technology

[0010] To sum up, there are many problems in the current iron-based waste as follows: 1) The complex shape makes analysis and sampling difficult and measurement inconvenient. At present, there is still no very effective method and technology to obtain sample information convincing both buyers and sellers, which seriously affects the The trade and cooperation between downstream restrict the comprehensive utilization of resources and the development of circular economy; 2) There are fire hazards in the process of transportation, loading and unloading, storage and production, which affect the safety of production; 3) Measures such as air isolation must be taken to reduce the iron-based The danger of combustion and explosion of waste during storage and transportation increases the cost, but sometimes iron-based waste spontaneously ignites or explodes due to various reasons; There is a safety hazard of spontaneous combustion during transportation and utilization
