Abstract
The invention relates to a method for extracting and separating rhenium from rhenium-containing slag. According to the technical scheme, the method comprises the following steps of: adding acid solvent of which the volume is 10 times as that of the rhenium-containing slag into rhenium-containing slag; heating material liquid at the temperature of between 60 and 80 DEG C for 60 to 90 minutes after dissolving the rhenium-containing slag; adding sodium hydroxide of which the weight is 1 to 10 percent of that the material liquid in to the material liquid; cooling to a room temperature, filtering, and heating and evaporating filtrate to remove the most moisture; adding precipitating agents, aniline blue and aniline black, of which the weight is 1 to 5 percent of the residual filtrate into the residual filtrate, and stirring for 30 minutes; filtering, and inputting hydrogen sulfide into the filtrate; and stirring, overnight aging, collecting precipitate at the bottom, and thus obtaining rhenium products. The method is simple, the rhenium is quickly recovered, the recovery rate of the rhenium is more than 80 percent, and the economic benefit, the social benefit and the environmental benefit are obvious.
Description
Technical field
The invention belongs to field of inorganic chemical engineering, relate in particular to the technology of extraction separation rhenium from rhenium-containing material slag.
Background technology
Social now, along with the continuous exploitation of resource, the mineral products of former primary state have been on the verge of exhaustion, and people put into sight the exploitation of some rare precious metal secondary resources more, namely extract rare precious metal from waste residue, waste liquid, dust.
The mineral of rhenium have seldom only been found out brightness rhenium ore deposit, molybdenum glance and copper rhenium sulfide mineral (CuReS so far
4), and how with micro-association in mineral such as molybdenum, copper, lead, zinc, platinum, niobium.The rhenium-containing mineral of economically valuable are molybdenum glance.The content of rhenium is between 0.001～0.031% in the general brightness concentrated molybdenum ore.But can reach 0.16% from the concentrated molybdenum ore rhenium-containing that porphyry copper is selected.The main raw material of producing rhenium is the byproduct of molybdenum smelting process.Smelting smoke dust and the slag of some copper mine, platinum family ore deposit, niobium minerals even zink sulphide and the waste liquid of handling low-grade molybdenum ore can reclaim rhenium.
Rhenium and molybdenum symbiosis are in molybdenum glance.When oxidizing roasting brightness concentrated molybdenum ore, produce a large amount of waste residues, the rhenium resource in the waste residue also is the resource that can not despise.Rhenium in the waste residue if can be extracted, can bring huge economic benefit, social benefit and environmental benefit.The extraction and separation method of existing rhenium mainly contains extraction process and ion exchange method, the method complexity.
Summary of the invention
The object of the present invention is to provide a kind of method simple, the method for extraction separation rhenium from rhenium-containing material slag that the rate of recovery is high.
The technical solution used in the present invention is for achieving the above object: a kind of from rhenium-containing material slag the method for extraction separation rhenium: the sour solvent that adds 10 times of volumes in the rhenium-containing material slag, after the dissolving, feed liquid was heated 60-90 minute down in 60-80 ℃, the sodium hydroxide that adds feed liquid weight 1%-10% then, after being cooled to room temperature, filter, after the filtrate heating evaporation removed most of moisture content, add the precipitation agent aniline blue black of filtrate weight 1%-5% in the residual filtrate, stirred 30 minutes, filter, feed hydrogen sulfide in filtrate, stir, placement is spent the night, collect the precipitation of bottom, be the rhenium product.
Above-mentioned a kind of from rhenium-containing material slag the method for extraction separation rhenium: described sour solvent is nitric acid and the 5% sulfuric acid mixed solution of 1:1-3 by volume.
The invention has the beneficial effects as follows: the present invention adopts sodium hydroxide as the precipitation agent of rhenium-containing material slag, and the rhenium rate of loss is below 5%.Adopt the present invention to reclaim the easy method of having founded that develops for the rhenium of China rare metal manufacturing enterprise.The present invention is raw material with rhenium-containing material slag, by method of the present invention, has realized the quick recovery of rhenium, realizes the rate of recovery of rhenium greater than 90%, economic benefit, social benefit and obvious environment benefit.
