Abstract

The invention discloses an environment-friendly artificial diamond production process which specifically comprises the following steps: S1, preparing pyrophyllite blocks and dolomite tube raw materials required by artificial diamond, crushing, sieving and crushing the pyrophyllite blocks by a crusher to produce pyrophyllite powder, and mixing the pyrophyllite powder, the dolomite powder and a sodium silicate solution under stirring; then sending the pyrophyllite blocks to a mold on a four-column hydraulic machine to be pressed and formed, and trimming and shaping the surfaces of the pressed pyrophyllite blocks for later use; S2, assembling a synthetic block: putting a graphite column and a conductive steel ring into a pyrophyllite block to form the synthetic block, and arranging the graphite column in the middle of the pyrophyllite block. According to the technical scheme, the trolley type roasting furnace is used for roasting to remove impurities instead of original acid boiling to remove impurities, sulfuric acid mist, sulfur dioxide and nitric oxide pollutants generated in the artificial diamond production process are effectively removed, and therefore the environment-friendly artificial diamond production process is achieved.

Description

technical field [0001] The invention belongs to the technical field of artificial diamond production, and in particular relates to an environment-friendly artificial diamond production process. Background technique [0002] Diamond, commonly known as "diamond", is what we often call diamond. It is a mineral composed of pure carbon and the hardest substance in nature. Since it was confirmed in the 18th century that diamonds are composed of pure carbon, people began to study artificial diamonds. It was only in the 1950s through the development of high-pressure research and high-pressure experimental technology that they achieved real success and rapid development. Synthetic diamond is also widely used in various industries and crafts. [0003] In the existing artificial diamond process, the impurity removal step is realized by acid boiling. The specific steps are to remove iron powder and some graphite and other impurities mixed in by the iron ball friction during the ball mi...
