A) done, teacher said that center top can be CuO or Cu (OH) 2 (just choose one, CuO). We eliminate unstable species and others... total 8 equilibrium (boundary line), at 10 ^ -3 (pic from wiki)

B) I don't know what compounds are needed to use here, HSC show me this (pic related)
This are some Cu-Cl diagrams I found:

Www.mkg.se/uploads/Arende_SSM2011_2426/SSM20112426_160_Bilaga_1_Svar_pa_begaran_degraderingsprocesser.pdf page 2
What are the "boundary lines" (equilibrium) that I need to use?

Got lost, what was your question?

How do you define the hydrometallurgical treatment of Copper?

If by that you mean get pure Cu out of. CuCl2 then
>>9059093
Shows how the stability line of Cu(s) goes down as the concentration of Cl(-) is risen.

This diagrams can be confusing but work, hope you never have to deal with triple azeotrope 3D diagrams, those are the worse.

- I create the Pourbaix diagram in A) almost identical to >>9059073 (change Cu(OH)2 to CuO, remember guys it's a simple diagram, "take it easy"... that's what teacher said me)

- then, in part B), I only take CuCl2- (others are "unstable" I guess) and change my diagram a little, like (b) and (c) in pic >>9059093

thanks bro, I really appreciate your help, I need help in part D) too, please

- part C) is in progress

(Sorry for my english)
