[QUOTE="WalnLiz, post: 4860, member: 147"] That's exactly right Gold miner....that's why many drop riffle arrangements on smaller sluices have a critical balance between sluice angle and water pressure. You up the water pressure or sluice angle to accommodate larger through put and that will lead to flour gold washing through, especially in high concentration black sand areas . See it happen all the time. Moral of the story ....don't expect boxes designed for small through put, especially drop riffle, with given " pressure to angle " ratios, to be mass fed and still recover a high % of flour gold. Cheers Wal. :) [/QUOTE]
