More marbles, or copper wadding?
I recently moved to marbles vs 6 plates.(sold on marbles bigtime) (6 plate SS rig with foot extension) On my spirit runs i have kept the foot of copper packing on top of the marbles but wondering how necessary this is. When I strip, I still keep the full column length as I need the height anyway to be able to output onto my counter.

Current Status of Copper-Ore Processing: A Review
IN PROCESSING COPPER ORES In recent times, a low copper content in ores has been observed (ores containing 0.2–0.3% copper are used for processing in Canada and the United States, and ores containing at least 0.4% copper are used in Russia [4]) owing to the exhaustion of rich copper resources. The flowsheet of processing copper ores is

Collectible Lutz Marbles
Lutz marbles were first made in the late 1800s in Germany. The process involved adding finely ground copper to the glass mixture, which created a metallic sheen. The name "Lutz" comes from the German word for "shiny.". These marbles were originally made as part of a line of high-end marbles that were sold to wealthy customers.

Innovations: How Hydrometallurgy and the SX/EW Process Made
The SX/EW Process. The SX/EW Process is a hydrometallurgical process since it operates at ambient temperatures and the copper is in either an aqueous environment or an organic environment during its processing until it is reduced to the metal. Because of its dependence on sulfuric acid, the SX/EW Process is at present not a substitute for, but ...
