So I was actually reading a random wikpedia article this afternoon about gold mining just for fun and this popped up -
Saying your conventinal sluice box loses about 60%, now maybe some of the old timers sluices were that bad, but honestly I would say most of the time our boxes probably recover somewhere from 90-99% of the gold depending on the area and the amount of heavys, and even in the hardest to work area we have ever found (all micro micro gold dust and insane amount of different types of heavy’s) I still find we are catching at a bare minimum at least 75% even when not classifying and being careful.
But I was wondering what is everyones standard sluice recovery rate, and at what point do you start slowing the flow down and trade efficency for recovery? Whenever we find we are losing anymore then a 1/5th of the gold we will generally slow the sluice down/decrease the angle or start classifying more, what is everyone elses preference on this?
