[0030] The first step: preparation of high-grade graphite products
[0031] Liaoning graphite mine, raw ore grade is 8.69%, other element analysis is as follows:
[0032]
[0033] 1. Take 400g of graphite raw ore, grind the ore for 4 minutes under the condition of grinding concentration of 65%, put the ground ore in a 1.5L flotation tank for 5 minutes of flotation; and regrind the roughed ore concentrate three times The re-election process, the grinding time is 6min, 8min, 10min respectively, and the flotation time is: 7min, 4min, 4min; the obtained concentrate grade is 90.88%.
[0034] 2. Take 20g of flotation concentrate, add NaOH solution with a concentration of 15% according to the liquid-solid ratio of 3:1, react in an autoclave at 180°C for 4 hours, and filter to obtain the filter residue.
[0035] 3. Get 10g of the ore (filter residue obtained in step 2) after high-pressure alkali leaching, add a concentration of 60% NaOH solution according to the alkali-mine ratio ...
