Pegasus/Degerstrom did not bust their gut trying to leach at -20 degrees. When freezing weather came they just shut down the pumps, drained all the lines and waited 5 months for it to warm up. In the spring, the first flush was the most rewarding as most of the dis-solution of the gold over the 5 months came out right away. Only cost for that 5 months of inactivity is the time value of money, and in a rising gold market who cares.

High PH of a cyanide solution lowers the freezing point somewhat but that is not significant IMO. Don't fight it, Shut it down before damage is done to the lines etc.
