Acid‐Assisted Ball Milling of Cellulose as an Efficient ...

Ball milling of cellulose in the presence of a catalytic amount of H 2 SO 4 was found to be a promising pre‐treatment process to produce butyl glycosides in high yields. Conversely to the case of water, n‐butanol has only a slight effect on the recrystallization of ball‐milled cellulose.As a result, thorough depolymerization of cellulose prior the glycosylation step is no longer required ...

Ore processing – Waihi Gold

The slurry that remains after this process has a very fine particle size. Typically, 80% of the ore particles are less than 70 microns in size (about the same consistency as fine beach sand). Such a fine particle size is required for gold liberation – the size required for the cyanide to be able to ‘see’ the gold in the leaching process.
