  In the context of the ``missing metals problem'', the contributions of the
UV-selected z=2.2 ``BX'' galaxies and z=2.5 ``distant red galaxies'' (DRGs)
have not been discussed previously. Here we show that: (i) DRGs only make a
marginal contribution to the metal budget (~ 5%); (ii) BX galaxies contribute
as much as 18% to the metal budget; and (iii) the K-bright subsample ($K<20$)
of the BX sample (roughly equivalent to the `BzK' selected samples) contributes
roughly half of this 18%, owing both to their larger stellar masses and higher
metallicities, implying that the rare K-bright galaxies at z>2 are a major
source of metals in the budget. We showed in the first paper of this series
that submm galaxies (SMGs) brighter than 3 mJy contribute ~5% (<9% as an upper
limit) to the metal budget. Adding the contribution of SMGs and damped Ly-alpha
absorbers, to the contribution of UV selected galaxies, implies that at least
30% of the metals (in galaxies) have been accounted for at z=2. The cosmic
metal density thus accounted for is ~ 1.3\times 10^6 \rhosun. This is a lower
limit given that galaxies on the faint-end of the luminosity function are not
included. An estimate of the distribution of metals in local galaxies as a
function luminosity suggests that galaxies with luminosity less than L^{\star}$
contribute about half of the total mass of metals. If the metals in galaxies at
z ~ 2 are similarly distributed then faint galaxies alone cannot solve the
`missing metals problem.' Galaxy populations at z ~ 2 only account for about
50% of the total metals predicted.
