Abstract
A kind of method that the invention discloses purifying gold hard rock, is placed in diamond and graphite mixture material in industrial microwave oven, is simultaneously introduced magnesium carbonate and stirs, sintering temperature is 300～600 DEG C, roasting time is 60min～80min, is subsequently cooled to room temperature, sends into shaking table and isolates diamond.The present invention reduces a large amount of production cost to put into, simultaneously effective improve operative's environment, reduce labor intensity；Optimize environment, eliminate a large amount of tail gas, waste water processing cost.
Description
Technical field
The present invention relates to diamond production technical field, a kind of method particularly belonging to purifying gold hard rock.
Background technology
In China superhard material Industry, the artificially synthesizing diamond now powder catalyst synthesis stem stem techniques that use more, High Temperature High Pressure,
In synthesis stem stem, part graphite is changed into diamond under powder catalyst effect.In diamond post processing purification process, powder
Catalyst diamond synthesizing pellet is after electrochemical process extracts catalyst metal, and gained material is the mixture of diamond and graphite,
Then enter purification of diamond committed step diamond, the separation of graphite.The purification of known synthetic superhard material
In Technology, ore-dressing technique is used to complete the thick purification of diamond according to diamond and the density variation of graphite, but due to water
The factors such as resistance, hydrone surface tension cause diamond particles and graphite microparticles differential settling velocity in water inconspicuous, no
Can fully remove graphite microparticles.According to the chemical characteristic of diamond Yu graphite, traditional handicraft uses the oxidisability of high-temperature high concentration
Acid technique (nitric-sulfuric acid technique, perchloric acid technique etc.) essence removes graphite, reaches the purpose that remove impurity purifies.This method exists
Major defect is: a large amount of uses of high concentration strong acid, and remove impurity creates a large amount of fumes of sulphuric acid and NOx gas while purifying, with
Time produce acid waste water, deteriorate production environment, tail gas, cost for wastewater treatment are high.
Summary of the invention
A kind of method that it is an object of the invention to purifying gold hard rock, decreases a large amount of production cost and puts into, simultaneously effective
Improve operative's environment, reduce labor intensity；Optimize environment, eliminate a large amount of tail gas, waste water processing cost.
Technical scheme is as follows:
A kind of method of purifying gold hard rock, is placed in diamond and graphite mixture material in industrial microwave oven, is simultaneously introduced
Magnesium carbonate stirs, and sintering temperature is 300～600 DEG C, and roasting time is 60min～80min, is subsequently cooled to room temperature, send
Enter shaking table and isolate diamond.
The consumption of described magnesium carbonate is the 8-12% of diamond and graphite mixture material quality.
The consumption of described magnesium carbonate is the 8% of diamond and graphite mixture material quality.
The consumption of described magnesium carbonate is the 12% of diamond and graphite mixture material quality.
The consumption of described magnesium carbonate is the 10% of diamond and graphite mixture material quality.
Compared with the prior art, beneficial effects of the present invention is as follows:
Graphite is removed in the purification that the present invention completes diamond by Physical, it is to avoid high concentration oxidizing acid and supporting height
The use of temperature response system, decreases a large amount of production cost and puts into, simultaneously effective improve operative's environment, reduce work strong
Degree；Optimize environment, eliminate a large amount of tail gas, waste water processing cost.
Detailed description of the invention
The method of 1 one kinds of purifying gold hard rocks of embodiment, is placed in diamond and graphite mixture material in industrial microwave oven,
Being simultaneously introduced magnesium carbonate to stir, sintering temperature is 300～600 DEG C, and roasting time is 60min～80min, is subsequently cooled to
Room temperature, sends into shaking table and isolates diamond, and the consumption of described magnesium carbonate is the 8% of diamond and graphite mixture material quality.
The purity of the diamond recording the present embodiment is 99.95%.
The method of 2 one kinds of purifying gold hard rocks of embodiment, is placed in diamond and graphite mixture material in industrial microwave oven,
Being simultaneously introduced magnesium carbonate to stir, sintering temperature is 300～600 DEG C, and roasting time is 60min～80min, is subsequently cooled to
Room temperature, sends into shaking table and isolates diamond, and the consumption of described magnesium carbonate is the 10% of diamond and graphite mixture material quality.
The purity of the diamond recording the present embodiment is 99.97%.
The method of 3 one kinds of purifying gold hard rocks of embodiment, is placed in diamond and graphite mixture material in industrial microwave oven,
Being simultaneously introduced magnesium carbonate to stir, sintering temperature is 300～600 DEG C, and roasting time is 60min～80min, is subsequently cooled to
Room temperature, sends into shaking table and isolates diamond, and the consumption of described magnesium carbonate is the 12% of diamond and graphite mixture material quality,
The purity of the diamond recording the present embodiment is 99.94%.
Its principle of the present invention is that after magnesium carbonate mixes with graphite mixture material with diamond, magnesium carbonate adheres to, penetrates into stone
Inside ink granule, during high-temperature process, magnesium carbonate decomposes to give off carbon dioxide, and the carbon dioxide drastically produced makes inclusion enclave graphite
Grain deform upon, become loose porous, use microwave heating, according to microwave have selectivity heating feature, utilize graphite and
Amorphous carbon more absorbs the feature of microwave under microwave field than diamond, rapidly heating diamond surface and free remaining stone
Ink and amorphous carbon, form the more conveying that " focus " becomes, and diamond be indifferent owing to absorbing microwave, and temperature is the highest, shape
Become " cold " center " thus to avoid diamond oxidized, reduce its bulk density, increase its molecular tension in water, who
Water buoyancy, and diamond particles quality is tight, physics, chemical change does not occurs, now carries out cleaning table separation, can be easily
Realize the magnesium oxide after bulk rear graphite granule and magnesium carbonate decompose and separate with diamond with current, reach accurate and purify Buddha's warrior attendant
The purpose of stone.
The ultimate principle of the present invention, principal character and advantages of the present invention have more than been shown and described.The technology of the industry
Personnel, it should be appreciated that the present invention is not restricted to the described embodiments, simply illustrating this described in above-described embodiment and description
The principle of invention, without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, and these become
Change and improvement both falls within scope of the claimed invention.Claimed scope by appending claims and
Equivalent defines.
