Abstract
The invention discloses a purification method of artificial diamond. The purification method comprises the following steps of: (1) carrying out non-destructive breaking; (2) carrying out electrolysis; (3) rubbing; (4) sorting out ore concentrate by using a swinging bed to serve as sorted materials, then rubbing and breaking the materials, and carrying out swinging bed sorting-circulation treatment. The purification method disclosed by the invention has the advantages that the defects in the prior art are overcome, the method is simple and the synthesized diamond rod particles after electrolysis are loose, so that the treatment is easy; the effect of treating electrolytic residue by selecting a rubbing machine is better, and after electrolysis, acid is not needed for dissolving the metal contained in the synthesized rod particles, so that the cost is reduced, and the labor intensity is relieved; after electrolysis, the acid used amount is greatly reduced, so that the cost is saved and the working efficiency and the economic efficiency are improved.
Description
Technical field
The present invention relates to Diamond Synthesizing Technology field, specifically belong to a kind of artificial diamond purifying method.
Background technology
In man-made diamond building-up process, sometimes have the block product that diamond and metal, graphite combines closely and occur, conventional acid handling procedure is difficult to be processed totally, disperses not open.Traditional technology is with chloroazotic acid or other agriculture strong acid is repeated multiple times boils, steeps, and even processes and is also difficult to for more than ten time process thoroughly, and technological process is longer, large by acid amount.Also useful electrolysis of hydrochloric acid steeps by corresponding oxide again, just the material through electrolysis is mixed fully and soaked with specific oxygenant and acid, and then come graphite and diamond to separate by the way of gravity separation, but electrolysis of hydrochloric acid causes atmosphere polluting problem, oxide compound uses the water pollution problems thoroughly not causing.
Summary of the invention
The object of this invention is to provide a kind of artificial diamond purifying method, overcome the deficiencies in the prior art, method is simple, and diamond rod particle synthetic after electrolysis relatively loosens and easily processes; The effect of selecting kneader to process electrolysis clout is relatively good, does not need to dissolve away metal contained in synthetic rod particle with acid after electrolysis, both reduces costs, improve again labour intensity, after electrolysis, greatly reduce by acid amount, cost-saving, increase work efficiency and economical efficiency.
The technical solution used in the present invention is as follows:
A kind of artificial diamond purifying method, the first step can't harm broken; Second step electrolysis; The 3rd step is rubbed; It is that separation by shaking table circular treatment is crumpled, is crushed to the material being sorted again that the 4th step separation by shaking table goes out concentrate.
The harmless broken material of the described the first step will through thick broken, one-level is broken, two-stage crushing, screening undersize material be by sorting, elects heavier material as electrolysis material.
Described second step electrolysis adopts electrolytic solution taking single nickel salt as electrolysis mother liquor, and Qi Zhongtie, nickel, cobalt, manganese, copper, aluminium composition weight percent, be iron 38.56%, nickel 53.46%, cobalt 0.07%, manganese 0.02%, copper 0.16%, aluminium 0.3%, and remainder is impurity.
Compared with the prior art, beneficial effect of the present invention is as follows:
The inventive method is simple, and diamond rod particle synthetic after electrolysis relatively loosens and easily processes; The effect of selecting kneader to process electrolysis clout is relatively good, does not need to dissolve away metal contained in synthetic rod particle with acid after electrolysis, both reduces costs, improve again labour intensity, after electrolysis, greatly reduce by acid amount, cost-saving, increase work efficiency and economical efficiency.The effect of selecting kneader to process electrolysis clout is relatively good, material is put into the vulcanite plate that two relative movement tightly press together and crumple certain hour, and the material after rubbing directly directly arrives separation by shaking table.
Embodiment
