Description
Известные гидрометаллургпческие способы очистки графита м молибденита , предназначенных дл изготовлени снециальных смазок, ог абразивных примесей не обеспечивают достаточной эффектнвнсстн ироiiecca очистки.The known hydrometallurgic methods for the purification of graphite and molybdenite, intended for the manufacture of specialty lubricants, with abrasive impurities, do not provide sufficient effective cleaning.
Обработку графита и молибденита но предлагаемому способу осуществл ют путем выщелачивани смесью сол ной н плавиковой кислот Е отпошенпи 9: 1 при плотиостн пульпы : 1 в течение 4-G час, на холоде (без нагрева). Оиераци ироизводитс в одну стадию в герметически закрытых барабанах из вииинласта или других матер алов. устойчивых к этим кислотам. Последующа обработка заключаетс в нромывке графита и молибденита водой и слабым раствором аммиака дл нейтрализации адсорбированной кислоты.The treatment of graphite and molybdenite using the proposed method is carried out by leaching with a mixture of hydrochloric hydrofluoric acid E from 9: 1 with pulp density: 1 for 4-G hour, in the cold (without heating). Hueraction is produced in one stage in hermetically sealed viiinlast drums or other materials. resistant to these acids. The subsequent treatment consists of washing the graphite and molybdenite with water and a weak ammonia solution to neutralize the adsorbed acid.
При предлагаемом способе очистки графит и молибденит получаютс высокой чистоты 99,85-99,95%, что делает их пригодными дл5 получени специальных смазок.With the proposed purification method, graphite and molybdenite are obtained in high purity of 99.85-99.95%, which makes them suitable for producing special lubricants.
