[QUOTE="user 4386, post: 439613, member: 4386"] I agree with the comment about flour gold staying in suspension when coarser gold drops out, but suggest the most common reasons for flour gold are usually: (a) that the hard-rock gold in the source area is fine-grained (so obviously alluvial gold derived from it can only be fine-grained), or (b) that you are far downstream from the source of the gold, so the coarser gold is farther upstream (has already dropped out) If you look under a hand lens, is the fine gold ragged or rounded? If ragged it is likely to be (a), if rounded it has hard to know which it is. [/QUOTE]
