Discussion on the optimal particle size in coal flotation |
| |
| Abstract: | Based on large volume of operation and experiment data, analyses were made on the influence of particle size in coal flotation, the effective equipment for coarse slime separation and effective method for fine slime separation. Proposal was given that: the most suitable size range in coal flotation be 0.25～0 075mm; low-cost gravitational equipment be employed for separation of +0.25mm coarse fines; more effective method be chosen for -0.075mm fine fraction according to its characteristics. |
