Problems solved by technology

[0002] During the synthetic process of synthetic diamond, sometimes there will be lumpy products tightly combined with diamond, metal and graphite, which are difficult to be cleaned by conventional acid treatment procedures and cannot be dispersed.
The traditional process uses aqua regia or other agricultural strong acids to boil and soak repeatedly for many times, and it is difficult to treat thoroughly even after more than ten times. The process is long and the amount of acid is large.
There is also the use of hydrochloric acid electrolysis and then the corresponding oxide bubbles, the electrolyzed materials are fully soaked with a specific oxidant and acid mixture, and then gravity separation is used to separate graphite and diamond, but hydrochloric acid electrolysis causes air pollution problems, oxidation Water pollution problems caused by incomplete use of chemicals

Embodiment 1

[0010] Example 1, a synthetic diamond purification method, the first step is to carry out non-destructive crushing; the second step is electrolysis; the third step is kneading; the fourth step is to separate the concentrated ore into the sorted material by shaking the table and then kneading and crushing To the shaker sorting cycle processing. In the first step, the non-destructive crushing materials need to go through coarse crushing, primary crushing, secondary crushing, screening and sorting of materials under the sieve, and select heavier materials as electrolytic materials. The second step electrolysis adopts electrolytic solution with nickel sulfate as electrolytic mother liquid, wherein iron, nickel, cobalt, manganese, copper, aluminum, silicon, magnesium constitute weight percent, are iron 38.56%, nickel 53.46%, cobalt 0.07%, Manganese 0.02%, copper 0.16%, aluminum 0.3%, silicon 0.01%, magnesium 0.01%, and the rest are impurities. It is better to use a kneading machin...

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 [0001] The invention relates to the technical field of diamond synthesis, in particular to a method for purifying artificial diamond. Background technique [0002] During the synthetic process of synthetic diamond, sometimes there will be massive products of diamond, metal and graphite tightly combined, which are difficult to be cleaned by conventional acid treatment procedures and cannot be dispersed. The traditional process uses aqua regia or other agricultural strong acids to boil and soak repeatedly for many times, even if it is processed more than ten times, it is difficult to process thoroughly. The process is long and the amount of acid is large. There is also the use of hydrochloric acid electrolysis and then the corresponding oxide bubbles, the electrolyzed materials are fully soaked with a specific oxidant and acid mixture, and then gravity separation is used to separate graphite and diamond, but hydrochloric acid electrolysis causes air pollution p...
