How to pickle the diamond segment with pickling?

At present, the pickling diamond segment is mainly used for the recovery of the segment. The purpose and significance of recycling the diamond segment are as follows:

Resource saving: diamond segment is a high-value material, and the diamond particles in it can be reused. Recycling diamond segment can reduce the demand for raw materials, thereby saving resources.

Environmental protection: the waste diamond segment may contain some harmful substances, such as welding materials, etc. If it is discarded without treatment, it may cause pollution to the environment, and recycling can avoid this from happening.

Economic benefits: recycling diamond segments can obtain certain economic benefits, and reprocessing them into new diamond tools or using diamond particles for manufacturing in other fields can create more economic value.

Social Responsibility: recycling diamond segments is also a kind of social responsibility, which can promote the sustainable development of the enterprise and improve the social image and reputation of the enterprise.
So how does pickling diamond work? It is mainly divided into the following steps:
1: Remove the brazing material binding the diamond: use chemical solvents or mechanical methods to remove the brazing material on the diamond segment. Mechanical methods include grinding and cutting, among others.

2: Cleaning the diamond segment: use chemical or mechanical methods to thoroughly clean the diamond segment.

3: Separation of diamond: put the cleaned diamond segment into a high-temperature autoclave for chemical decomposition, and separate the diamond from other impurities. Usually the following steps are required:

1) Pickling: put the waste diamond segment into the mixture of concentrated nitric acid and concentrated sulfuric acid to dissolve and remove the metal part.

2) Oxidation: put the waste diamond segment into the oxygen atmosphere under high temperature and high pressure to oxidize and remove the residual organic matter.

3) Separation: sieve or centrifuge the processed material to separate the diamond particles from the metal powder.

4) Washing: the separated diamond particles are washed several times to remove residual acid and impurities to ensure the purity and quality of the diamond.

4.Inspection of diamonds: carry out quality inspections on the separated diamonds, including inspections of color, shape, size, purity, etc.

5. Grinding diamonds: grinding qualified diamonds into suitable particle sizes, which can be used to produce high-tech products such as diamond tools and electronic components.
It should be noted that the above steps are for reference only, and it needs to be adjusted and improved according to specific situations in actual operation. At the same time, due to the high hardness and wear resistance of diamond, the separation process is difficult and requires the use of special equipment and techniques. Therefore, it is recommended to operate under the guidance of professionals.
