ABOUT)

Co 1 The invention relates to a recipe for grinding abrasive pastes for finishing operations and can be used in metal processing technology. The purpose of the invention is to increase the productivity of the process of grinding metal surfaces and improving the sanitary and hygienic working conditions; The paste preparation technique consists of mixing the ingredients until a uniform consistency is obtained. The compositions of the proposed lapping abrasive paste with the reduction of the components are given in table 1. To prepare the paste, the tails of ferruginous quartzites from 3 different deposits are used, which differ in the ratio of components. Table 2 shows the composition of the used tailings of the enrichment of ferruginous quartzites. Table 3 shows the productivity values of the abrasive paste according to examples 1-3 of table 1, in comparison with the known paste and control pastes (using the enrichment tailings of ferruginous quartzites of composition 6 of table 2). . Table 4 shows the performance values of the abrasive paste according to Example 2 of Table 2. using different compositions of tailings of enrichment of ferruginous quartzites, given in table 2.
