Sounds like a good place to use concrete septic or cistern tanks! That would even help out the local plumbers!! I think the cement tanks filled with iron plate, solution in one end and out the other! What a brilliant idea!! as always!! CPRK ROCKS!!

Thanks Slammer, that was an excellent article. The copper comes off as a precipitate, a sludge on the bottom. For shipping to the smelter we can get two or three times the Cu percentage as in our Ccon, from as little as .02% copper in solution.

I agree. That copper cementation article covers the points we want to know. I'll extrapolate a bit further. As today's PR states, this is a leaching operation for the copper oxide ore(s). Presumably the sulfide ore(s) go to the flotation circuit and the oxide ores have not, at least in quantity. Leaching is usually done with dilute sulfuric acid which dissolves the copper compounds (water does not dissolve most copper compounds). So, WUCC will need a leach pad (ground preparation for proper drainage, layers of impervious coverings that will tolerate being loaded with tons of crushed rock, overflow ponds for extreme rain events, etc.), sulfuric acid tanks, a source for iron scrap that is appropriate for cementation use, and the cementation circuit equipment. I don't think the sulfuric acid is strong enough to be an immediate health risk. Also, very long term, if they put in a smelter, a side product might be the sulfuric acid they use for leaching.

Another decades old technology to make some bucks with. Mill tours will continue to be very interesting!

Thanks slamdunk that was in good laymans terms. Now I understand the process.
