Abstract
A kind of method of new extracting metals gold is characterized in that, has abandoned cyanide process and mercury plate absorption method commonly used, has adopted new infusion solution to leach.Owing to use new gimmick provided by the invention, do not re-use objectionable impuritiess such as containing cyanogen and mercury, therefore, present method has nontoxicity, non-environmental-pollution, low, the high advantage of recovery metal gold rate of cost in the field of extracting metals gold, have good use value and implementation prospect.
Description
As is generally known the method for extracting metallic gold from gold containing ore generally is divided into the step of three phases.Fs is the processing in early stage of ore, and subordinate phase is to leach, and the phase III is to smelt, and wherein, it is important the leaching stage.Usually, the leaching method that the extracting metals gold uses in gold containing ore has cyanide process and mercury silver plate absorption method.Using cyanide process is to contain the cyanogen hypertoxic drug, to mix water, adds alkaline matter again and puts into ore, makes metallic gold become liquid and flows out.It is poisonous to leach employed medicine with cyanide process, be difficult to obtain, and the cost height, the rate of recovery of gold is low, simultaneously, and the use meeting serious environment pollution of this method.And use mercury silver plate absorption method, and polluting the environment equally, its cost is also higher, and the rate of recovery of gold is low, is difficult for extracting metallic gold in the low ore of Gold Content.
In order to solve and overcome the problem and the defective of prior art, the invention provides a kind of new nontoxic, pollution-free, cost is low, the process for extracting of the metallic gold that the rate of recovery of gold is high, thus improved the utilization ratio of national gold ore resource greatly.
The process for extracting of new metallic gold provided by the invention, its projecting point is not re-use cyanide process and mercury silver plate absorption method, and be to use a kind of new leaching method that the gold mine product are leached, thereby a series of problems that when the extracting metals gold, produce have for many years been solved.
The main technique flow process of the process for extracting of new metallic gold provided by the invention is as follows: 1. according to the different situations of ore, select different earlier stage processing methods, ore is pulverized, sulphur removal or remove clay in the breeze; 2. ore is leached processing, promptly the ore powder of handling well is sneaked into an amount of Manganse Dioxide (M
nO
2), Potassium Bromide (KB
r), potassiumiodide (KI), sodium-chlor (N
aCL), water (H
2O) etc., add an amount of sulfuric acid liquid H again
2SO
4Stir evenly, its proportioning is: Manganse Dioxide (M
nO
2) 1000: 1-10000: 1, Potassium Bromide (KB
r) and potassiumiodide (KI) in right amount, the sulfuric acid (H of 25% concentration
2SO
4) an amount of, sodium-chlor (N
aCL) 100: 1-100: 1.5.Leaching through after a while just obtains containing gold perchloride (A
uCL
3) leach liquor; 3. the work of smelting the stage be the leach liquor that will obtain after adsorption treatment, heating to smelt just can obtain metallic gold.
Use method provided by the invention to compare, have following outstanding advantage with prior art:
The first, the used raw material of new infusion solution is easy to get, and cost is lower, and used equipment is also simpler.
The second, use new leaching method, no cyanogen, no mercury, nontoxic, pollution-free have solved the difficult problem of environment protection for many years.
The 3rd, the gold recovery that uses the inventive method acquisition is near 100%, the refinement rate of recovery of metallic gold is higher than 90%, therefore, be applicable to the ore that Gold Content is low, can save greatly and reduce cost, improve utilization rate, illustrate that the present invention is the new method that a kind of utmost point has the application prospect national precious resources.
The present invention is further illustrated below in conjunction with an embodiment:
Select three tons in the gold trisulfide ore of Gold Content 3.1 gram/tons, it is crushed to 180 orders, fuse desulfuration after the flotation, in the ore powder of handling well, sneak into Manganse Dioxide (M
nO
2) its proportioning is 1000: 1, Potassium Bromide (KB
r) an amount of, potassiumiodide (KI) an amount of, sodium-chlor (N
aCL) an amount of and water (H
2O) stir evenly the sulfuric acid (H that the back adds 25% concentration
2SO
4) an amount of, stir evenly again, leach and obtain containing gold perchloride (A after 48 hours
uCL
3) leach liquor, the leach liquor of gained is carried out adsorption treatment, then, heating to smelt just can obtain metallic gold.
Claims (2)
1, a kind of method of extracting metals gold is smelted three key steps by processing in early stage, leaching, the later stage of ore and is formed, and it is characterized in that: the solution of leaching is by Manganse Dioxide (MnO
2), iodine bromide IBr (KBr), potassiumiodide (KI), sodium-chlor (NaCL), sulfuric acid (H
