H2SO4 cells. If you are talking about H2SO4 electrolysis in a concentrated sulfuric stripping cell, the last thing you want to do is run it hot. It starts attacking the base metals. Anything above about 110F and you start having problems. For copper refining in a copper sulfate/dilute H2SO4 cell, I think the temp is maintained between 104-122F.

What is Gold Refining. Gold refining is the process of purifying raw gold to remove impurities and separate it from other metals or materials. The goal is to produce high-purity gold, often reaching 99.9% or higher. Refining can be done using various methods, depending on the composition of the raw material and the desired purity level.

In this method, gold ions are separated from other existing ions using an electrolysis process and using a surface which is permeable to impurities and impermeable to gold. Finally, the solution containing gold ions is precipitated by reducing chemicals, and a product with a grade of 99.95 % is obtained (Shor, 1992).

The 1/2" hole locked it all together. The bar was about 3" x 8". The other hole was for the cable connection. Lots cheaper than gold and it lasted a couple of years. As you probably know, the big boys use gold candlesticks for both the anode and cathode connections. Just making conversation. Chris
