Depends what kind of Acid is used:

Cu10(PO4)6(OH)2 + 20 H+ => 10 Cu2+ + 6 H3PO4 + 2 H2O

but it could be also

Cu10(PO4)6(OH)2 + 2 H+ => Cu10(PO4)6 2+ + 2 H2O

or

Cu10(PO4)6(OH)2 + 2 H+ => 3 Cu3(PO4)2 + Cu 2+ 2 H2O

pH 4 means weak acid. So the copper phosphate will precipitate. The last equation I think will take place.

I dumno means: I do not know
