Известен метод очистки продукта синтеза алмаза от примесей, по которому основную массу графита удал ют путем обогащени исходного материала в т желых жидкост х. Однако обогащение в т желых жидкост х тароизводитс вручную, малыми порци ми, а жидкости токсичны и дороги.A known method for purifying the product of diamond synthesis from impurities, according to which the bulk of the graphite is removed by enriching the starting material in heavy liquids. However, enrichment in heavy liquids is produced manually, in small portions, and liquids are toxic and expensive.
Известен также флотационный метод обогащени продукта синтеза алмаза. Но применение его также ограничено, так как поверхкость алмазов покрыта пленкой графита, что усложн ет селективное разделение.A flotation method is also known to enrich the product of diamond synthesis. But its application is also limited, since the surface of diamonds is covered with a graphite film, which complicates the selective separation.
По предлагаемому способу графит перевод т в ленный продукт, а алмазы депреосируют .In the proposed method, graphite is converted into a folded product, and diamonds are depreated.
Достигаетс это тем, что дл очистки поверхности зерен алмазов от покрывающих ихThis is achieved by cleaning the surface of the diamond grains from covering them
пленок примесей, продукт синтеза обрабатывают азотной КИСЛОТОЙ и окислительной смесью , Состо щей из хромового ангидрида и серной кислоты. При такой обработке происходит и подавление алмазов.films of impurities, the product of the synthesis is treated with nitric acid and oxidizing mixture, consisting of chromic anhydride and sulfuric acid. With such processing occurs and the suppression of diamonds.
Предмет изобретени Subject invention
Способ обратной флотации синтетических алмазов, отличающийс тем, что, с целью очистки поверхности зерен от покрывающих их пленок примесей и подавлени алмазов , продукт синтеза подвергают обработке азотной кислотой и окислительной смесью, соСто щей из хромового ангидрида и серНОЙ кислоты.The method of reverse flotation of synthetic diamonds, characterized in that, in order to clean the surface of the grains from the impurity films covering them and suppress the diamonds, the synthesis product is treated with nitric acid and an oxidizing mixture consisting of chromic anhydride and sulfuric acid.
