METHOD FOR GRAPHITE PRODUCTION Russian patent published in 1995 - IPC

Abstract RU 2047557 C1

FIELD: chemical engineering; graphite production. SUBSTANCE: method involves crushing 450 kg of graphite- containing powder of cyclone separation, extracting (- 2.0)-(+0.1)mm class, crushing it in ball mill to reach 70-75% coarseness degree of class 0.07 mm, exposing it to magnetic separation with magnetic field intensity 1000- 1100 oersted and floatation separation using collector and foaming agent higher aliphatic alcohols bottoms in the concentrations of 400-450 g/t. EFFECT: enhanced effectiveness of waste recycling. 2 tbl
