Abstract
1. Способ получения баритового концентрата, пригодного для использования его как утяжелителя в буровых растворах, включающий флотационное обогащение баритосодержащих руд и модифицирование поверхности частиц полученного флотационного баритового концентрата, отличающийся тем, что модифицирование флотационного баритового концентрата осуществляют в процессе обратной флотации в присутствии реагента-модификатора.2. Способ по п.1, отличающийся тем, что флотационное обогащение баритосодержащих руд проводят в присутствии жирно-кислотного собирателя, например собирателя на основе жирной кислоты и регулятора полимеризации фенольного антиоксиданта - Агидола-1.3. Способ по п.1 или 2, отличающийся тем, что в процессе обратной флотации для модифицирования поверхности частиц баритового концентрата используют углефосфатный реагент или его водный раствор, представляющий собой смесь триполифосфата натрия и/или тринатрий фосфата и натриевых или калиевых солей гуминовых кислот.4. Способ по п.1, отличающийся тем, что перед проведением обратной флотации проводят классификацию флотационного баритового концентрата путем сепарации на гидроциклоне фракции более 70 мкм. 1. A method of producing a barite concentrate suitable for use as a weighting agent in drilling fluids, including flotation concentration of barite-containing ores and surface modification of particles of the obtained flotation barite concentrate, characterized in that the modification of flotation barite concentrate is carried out in the process of reverse flotation in the presence of a modifying reagent. 2. The method according to claim 1, characterized in that the flotation concentration of barite-containing ores is carried out in the presence of a fatty acid collector, for example a collector based on a fatty acid and a phenol antioxidant polymerization regulator Agidol-1.3. The method according to claim 1 or 2, characterized in that in the reverse flotation process, a carbon phosphate reagent or its aqueous solution is used to modify the surface of the particles of barite concentrate, which is a mixture of sodium tripolyphosphate and / or trisodium phosphate and sodium or potassium salts of humic acids. The method according to claim 1, characterized in that before carrying out reverse flotation, a classification of flotation barite concentrate is carried out by separation of a fraction of more than 70 microns on a hydrocyclone.
