"The first time I saw a Knelson concentrator in action was at HBM&S's Photo Lake Mine mill (old Stall Lake mill) at Snow Lake, Manitoba. At the time, we were mining 9% Zn, 3% Cu and 0.13 oz/t Au. We were supposed to be at a base metal mine but in actuality we were producing more gold per tonne than they were finding at the New Britannia Mine in town! The barrel beneath the concentrator was open at the top and full to the brim with heavies. I was completely in awe with the thought of all the gold that was contained in that 45 gal. drum."
